White Card Update:
   Unions Concern over Asbestos Exposure

According to a recent report in TheAge.com.au Unions are pushing for the establishment of a
National Asbestos Authority. The initiative is being spearheaded by lifelong asbestos
campaigner Paul Bastian of The Australian Manufacturing Workers Union.

TheAge.com.au had this to report in the issue:

UNIONS will push for the establishment of a National Asbestos Authority to protect people and
to remove asbestos from homes and public and commercial buildings.

 The Australian Manufacturing Workers Union acting national secretary, Paul Bastian, will meet
the Prime Minister, Julia Gillard, and the Workplace Relations Minister, Bill Shorten, this
afternoon to push the case. He is a lifelong campaigner against asbestos.

Mr Bastian says more Australians have died from exposure to asbestos than in World War II.

''Surely we've had enough people die now, enough heart-wrenching diseases and enough legal
acknowledgment that this must stop,'' he said.

The union's solution is a federally funded authority to ''find, educate, remove and protect people
from the dangers of asbestos''.

The authority would educate and raise awareness within the community of the existence of
asbestos in private homes, businesses and public buildings.

''As part of the authority, an urgent audit and plan for the removal of asbestos from all
government premises is required.

 ''State governments regularly report low levels of compliance with asbestos regulations and we
call on the federal government to treat its removal as a national issue of critical importance -
including asbestos in schools.''

Mr Shorten's spokesman said it was a critical issue for the government.

''Which is why we commissioned the asbestos management review - the minister and the
government look forward to receiving the report's recommendations,'' he said.
The Herald understands the review will be handed to the government later this week and is
likely to recommend some form of national authority.

The most alarming fact is that Australia has the highest death rate from mesothelioma in the
world, and the death toll continues to rise. A startling estimate that up to 18,000 more
Australians will die from mesothelioma by 2020 highlights the need for the action plan to be
implemented as soon as possible. Contractors and employers undertaking construction on old
sites need to be more aware of the presence of asbestos and undertake the necessary tests
prior to work beginning on the site



The call from unions comes in the wake of a suspected asbestos contamination on a BHP
Billington mining site. According to CFMEU spokespeople workers at the company’s Jimblebar
iron ore mine are using construction materials contaminated by asbestos.

A report by Abc.net.au has more:

The material, used to bed pipes and make concrete, appears to have come from a Newman
quarry.

 Steve McCann, Safety Officer for the CFMEU's WA Branch, says despite the quarry being
closed, material that's been shipped to the mine hasn't been isolated.

 "There's no more material coming out of that quarry, but the material that's been stockpiled on
this site, Jimblebar, is still being used."

A spokesperson for BHP Billiton disagreed with the union, saying the material has been
quarantined and its handling by the workforce at Jimblebar has ceased.

                        Reasons why Asbestos Poses such a Threat

According to the unions asbestos has killed more Australians than World War 2, with
mesothelioma, pleural disease and asbestosis being the most dangerous of the side effects.
Here we discuss each of these diseases associated with asbestos poisoning.

Mesothelioma is another type of cancer that could occur as a result of asbestos exposure. It is
cancer of the pleura and may only occur 20 to 40 years after the exposure occurs. This disease
grows and spreads quickly before the symptoms appear which makes early diagnosis and
treatments harder. The average survival time after diagnosis is only 6-18 months. A very small
exposure to asbestos can be enough to trigger the cancer, however only a small percentage of
people exposed to asbestos develop mesothelioma.
Pleural disease is another dreaded disease associated with asbestos. This is when the outer
lining of the lung, called the plura becomes irritated and inflamed. This outer lining then stiffens
and thickens and can become filled with liquid, which can hamper normal breathing and restrict
oxygen intake.

Asbestosis is when lungs become scarred causing airways to become inflamed and scarred,
retricting the flow of oxygen to the lungs and into the blood. The lungs become stiff and
inelastic, making breathing more difficult. Symptoms include tightness in the chest, dry cough,
and in the later stages, a bluish tinge to the skin caused by lack of oxygen. Asbestosis is usually
seen in former asbestos miners, asbestos manufacturing workers and insulation workers. The
scariest part about this disease is that it can take up to 10 years for symptoms to show up,
which makes diagnosing harder.

Most Common Injuries
                        on Construction Sites

Some of the most common causes of injury on a construction site involves falling hazards,
electrical hazards, working with cranes and machinery and working from scaffolding.

                                         Falling Hazard

The most common occurrence of incidents on construction sites involve workers falling
according to statistics provided by authorities. This type of hazard also causes the most serious
injuries. Extreme caution must be administered when working from a height, especially a height
higher than 2 meters. Workers need to be aware of your surroundings and take note and
caution of slippery boards on scaffolds and walkways, missing guardrails, openings in floors and
penetrations that are not correctly protected. Report all openings or missing railings so they can
be corrected as soon as possible.

Relating to the hazard of falling is the issue of scaffolding work. When work from heights cannot
be eliminated, the use of scaffolding is necessary. To comply with the applicable scaffolding
regulations, all persons erecting or altering scaffold must be competent and certified to do so.

All scaffolds must be erected in compliance with statutory regulations and such scaffold and
accessories must conform to regulations. Any damaged planks must be removed, kickboards
must be secured in place and guardrails installed.

Mobile scaffolds present their own hazards, in that they are frequently used and must be
erected as per regulations. They should be fitted with wheel locks which must be in place
whenever people are working on the scaffold so that it doesn’t roll causing a fall.

All scaffolds should have an internal ladder for access. Climbing of scaffolding standards should
not be allowed and tools and equipment should not be left lying around unattended on scaffolds
as they tripping hazard they present can be compounded by a fall from a height.

Personal Protective Equipment is the form of Safety helmets must be worn at all times when
working from a scaffold. Workers must be provided with a safety helmet which must be worn at
all times.
Electrical Hazard

The occurrence of electrocutions on construction sites is a prevalent danger that requires
attention. This is a hazard that can be minimised if workers follow the correct safety and
preventative procedures as most cases of electrocution are caused by a form of negligence.

As far as electrical installations are concerned on sites a qualified electrician must carry out all
repairs to equipment and electrical installations, including repair and replacement.

The basic rules to remember are to keep electrical leads off the ground and on stands and do
not hang leads from scaffolding. Do not use double adaptor fittings or overload adaptors.

Replace all damaged leads, wiring, equipment or installation and report faults immediately.

During rainy weather covers must be provided for equipment exposed to the elements, if covers
cannot be provided then equipment must not be used as electrocution can result.

Workers should not touch wires or cords that they are unfamiliar with especially if they don’t
know whether it is live or not.

                                   Explosive-Powered Tools

The very nature of this tool makes it a hazard. These tools use an explosive charge to fire
fixings into concrete, steel and timber, and, like a firearm and therefore they are potentially
lethal. These can only be operated by trained persons, who are wearing the correct safety
glasses and hearing protection. Signs must be placed in the area of operation of this equipment
to warn passers-by of the danger they present. These tools should not be left unguarded and
especially not in a loaded condition. All explosive-powered tools must be inspected and
maintained on a regular basis as all machinery should be. They should be locked away when
not in use, they are dangerous and are a loaded weapon in the wrong hands.

                                              Cranes

Just last week another worker was crushed by a crane on a construction site. This occurrence is
only too common of late. It is important that only authorised certificated operators will be
permitted to operate cranes. Crane Operators and Doggers must work in close terms with each
other, each should know what the other is doing, and they need to co-operate and communicate
in order to avoid dangerous situations. Crane Doggers should be directing crane operators only.
Irresponsible behaviour m,ust be avoided such as riding the load which is strictly prohibited.
Slings, ropes and chains are to be checked on a daily basis and monitored for any signs of
wear. Workers must keep their hands clear of pinch points and away from slings on loads, as
they can easily become caught. Loads must be correctly slung and workers should never stand
under loads, this is another reason workers get crushed by the load. Crane and mobile
machinery operators must check clearance of electrical power lines when setting up or
operating as the danger of electrocution is very prevalent. Any defects with cranes, machinery
and associated gear must be reported to those in charge immediately.
By following a few simple rules, workers on construction sites can minimise the risks associated
with this dangerous work. White Card and Site specific training is the most important tools in the
arsenal of construction employers in ensuring that their workers are aware of the hazards and
know how to respond to them successfully.

White Card Update:
               Trench and Excavation Safety

All construction industry workers are aware that the industry is one that holds many dangers as
well as many rewards. In order to succeed in this dynamic and ever changing industry, workers
need to value safety above all else. One of the major hazards construction workers face is
presented by Trenching and Excavation. Although workers will receive the necessary training,
we will refresh workers with the basics in this post.

In order to work safely in the vicinity of trenches or excavations employers and employees need
to identify hazards associated with trenching and excavation work, assess risks and eliminate or
minimise those risks before, during and after the performance of work.

Prior to commencement of work a site investigation should be carried out, in which as much
information as possible is obtained about the ground conditions.

The duty of an employer according to WH&S legislation is to provide safe systems of work,
instruction, training and supervision to ensure that employees are safe from injury.

When deciding on a system of ground support for an excavation or trench consider the nature of
the ground, weather conditions an proximity of in-ground services. Employers who ignore this
step often find themselves in the middle of incidents that result in injury.

Examine the area where the work is to be carried out, conduct a risk assessment and
implement appropriate control measures.

Excavations of more than 1.5 metres in depth require an engineer to assess the site conditions
and prepare an engineer’s report which will be used to implement safety control measures.

Many factors can influence the stability of trenches or excavations. These include static and
dynamic loads, including the spoil pile, adjacent buildings, ground vibration and wet or dry
conditions. Safe systems of work must be used to ensure the conditions at the site are safe. The
site must be left in a safe condition when work is not in progress.

Inspection should be carried out daily in order to ascertain that the trench or excavation is
stable. This includes surveillance of trench walls, support systems and excavations should be
carried out frequently and recorded. During these inspections the following should be observed:
    both the trench and excavation walls are not undercut.
        supports are not overstressed.
        ground is not fretting or beginning to collapse.
        look out for tension cracks along the trench or excavation surface.
        the trench or excavation walls do not sag under the increased pressure from plant or
         equipment.

Persons should not work alone in a trench due to the danger involved. Workers in the vicinity of
the trench must wear the appropriate PPE, including hard hats, safety boots, safety vests,
safety glasses and gloves. The appropriate equipment should be determined as part of the risk
assessment.

Signage and barricades are also important around the hazardous area to warn workers and
others of the dangers of the hazard.

It is important for construction workers to remember the golden rule of any Confined Space
including trenches and excavations: Do not attempt to enter a confined space unless you are
fully trained and know what you are doing!

Confined space entry and exits are a particularly important area to address.

Tunnels, shafts and trenches present a major safety hazard and the importance of having entry
and exit openings that are large enough for a properly equipped person to pass through should
be understood. The size and number of openings also have an impact on the ventilation.
Confined space entry is a specialised field and requires training and thorough understanding of
the appropriate work and safety products.

Workers entering a confined space should be trained in:

•        The nature of hazards associated with confined spaces

•        Necessary precautions that need to be taken

•        Proper use of PPE

•        Emergency case procedures

•        Personnel must be adequately trained in rescue and first aid

•        Follow defined entry procedures –

Steps for working in Trenches, Excavations Or other confined spaces:

    1.   Perform a review determining whether working in the space is absolutely necessary
    2.   Consider substituting work with less hazardous work activities
    3.   Gain authority to enter the confined space
    4.   Ensure all workers wear PPE
    5.   Ensure engineering controls are in place to separate other workers from the hazard
6. Determine if there is a need to set up additional training, maintain supervision, develop
     rosters and do whatever is reasonably necessary to ensure safety in the confined space.
  7. By working together and keeping communication open workers and employers can
     ensure safety when working in confined spaces is upheld.

Tragedy Hits Construction Site - Worker
               crushed by Crane


An incident in The USA recently has cast a dark cloud over the use of cranes in construction. A
crane operator was killed when the crane he was operating collapsed, trapping him in the cabin
for over 5 hours. A report by Abclocal.go.com had this to say:

A construction worker who was using a crane to lift a large cement wall was killed after that
crane collapsed. It happened at the old Garden Ridge on I-45 near The Woodlands which was
destroyed by an arsonist last October.

Crews worked all afternoon to lift the large crane from its side. The operator had been trapped
in the machine's cab for several hours.

It's a disturbing image of a crane toppled over that had a group of worried spectators watching
and waiting several hours for help at a construction site near The Woodlands.

Sgt. Joe Smart with the Conroe Police Department said, "It looks like it pinned the cab where
the operator sits under the weight of the crane."

Emergency workers who rushed to the scene couldn't immediately rescue the crane operator,
who has been identified as Luis Ruiz. Police say the man was among a group of contractors on
this site rebuilding the Garden Ridge that burned down last year.

Deena Nicholson of The Woodlands said, "It's really, really sad. It just seems like help is taking
so long."

Eyewitnesses told police something just went wrong.

"It looks like he was lifting one of these concrete walls to begin construction of this building, and
I'm told it was the first wall of the new building," said Sgt. Smart.

The crane operator was trapped inside the cab for nearly five hours before help finally arrived.
Police say they were waiting for large trucks and heavy equipment to lift the machine. As for the
crane operator, sadly investigators say this accident appears to be tragic.

Family members tell me the operator's been in construction for about 40 years. They call him a
devoted husband and father.
OSHA investigators are on the scene.

Source: http://abclocal.go.com/ktrk/story?section=news/local&id=8718021

Sadly it is too late for this operator and his family but other operators on construction sites
around Oz do not need to suffer the same fate. No matter how dangerous crane work may be,
workers can minimise the risk involved by being alert and complying with safety regulations.

A crane is a powerful tool used for shifting heavy loads to and from a vehicle. Many fatalities
have occurred where workers were crushed by cranes, either when the load shifts unexpectedly
or a malfunction occurs.

Employers have a responsibility to ensure that they provide a safe work environment, safe
systems of work and plant and substances are in a safe condition.

Any operator needs to be certified to do so and be in possession of appropriate certificates of
competency for Crane operation and Dogging.

Employers must ensure that a hazard identification and risk assessment is carried out and that
safe systems of work are implemented as control measures for all operations. They must also
ensure that all crane operators are qualified and certified to operate the cranes. Operators must
also be trained in the safe operation procedure for the crane being used.

Another problematic area is when operators accidentally bump levers causing unintended
movements. Controls should be clearly and permanently marked and all bump bars/guards
should be installed around the controls to prevent this inadvertent lever operation which can
often prove fatal.

Operators carry great responsibility and need to be aware of the danger zones on site that is the
areas where the operator may be hit by the load or the boom section of the crane and avoid
entering the danger zones while operating the crane. Operators are also responsible for
monitoring the load stability and adhere to the manufacturer’s instructions in operating the
crane.

Problems may arise from load slinging. These situations can be controlled successfully by
consulting with the workers and planning safe work strategies.

As with all risks on construction sites, the hazards of cranes can be controlled and managed to
avoid injury with a little planning by employers. Operators can assist by remaining alert behind
the control and remembering their safety training whenever they are at the controls.

White card update unions concern over asbestos exposure

  • 1. White Card Update: Unions Concern over Asbestos Exposure According to a recent report in TheAge.com.au Unions are pushing for the establishment of a National Asbestos Authority. The initiative is being spearheaded by lifelong asbestos campaigner Paul Bastian of The Australian Manufacturing Workers Union. TheAge.com.au had this to report in the issue: UNIONS will push for the establishment of a National Asbestos Authority to protect people and to remove asbestos from homes and public and commercial buildings. The Australian Manufacturing Workers Union acting national secretary, Paul Bastian, will meet the Prime Minister, Julia Gillard, and the Workplace Relations Minister, Bill Shorten, this afternoon to push the case. He is a lifelong campaigner against asbestos. Mr Bastian says more Australians have died from exposure to asbestos than in World War II. ''Surely we've had enough people die now, enough heart-wrenching diseases and enough legal acknowledgment that this must stop,'' he said. The union's solution is a federally funded authority to ''find, educate, remove and protect people from the dangers of asbestos''. The authority would educate and raise awareness within the community of the existence of asbestos in private homes, businesses and public buildings. ''As part of the authority, an urgent audit and plan for the removal of asbestos from all government premises is required. ''State governments regularly report low levels of compliance with asbestos regulations and we call on the federal government to treat its removal as a national issue of critical importance - including asbestos in schools.'' Mr Shorten's spokesman said it was a critical issue for the government. ''Which is why we commissioned the asbestos management review - the minister and the government look forward to receiving the report's recommendations,'' he said.
  • 2. The Herald understands the review will be handed to the government later this week and is likely to recommend some form of national authority. Read more: http://www.theage.com.au/opinion/political-news/unions-call-for-asbestos-authority- 20120626-210i0.html#ixzz1yzBvJl2Y The most alarming fact is that Australia has the highest death rate from mesothelioma in the world, and the death toll continues to rise. A startling estimate that up to 18,000 more Australians will die from mesothelioma by 2020 highlights the need for the action plan to be implemented as soon as possible. Contractors and employers undertaking construction on old sites need to be more aware of the presence of asbestos and undertake the necessary tests prior to work beginning on the site The call from unions comes in the wake of a suspected asbestos contamination on a BHP Billington mining site. According to CFMEU spokespeople workers at the company’s Jimblebar iron ore mine are using construction materials contaminated by asbestos. A report by Abc.net.au has more: The material, used to bed pipes and make concrete, appears to have come from a Newman quarry. Steve McCann, Safety Officer for the CFMEU's WA Branch, says despite the quarry being closed, material that's been shipped to the mine hasn't been isolated. "There's no more material coming out of that quarry, but the material that's been stockpiled on this site, Jimblebar, is still being used." A spokesperson for BHP Billiton disagreed with the union, saying the material has been quarantined and its handling by the workforce at Jimblebar has ceased. Source: http://www.abc.net.au/rural/wa/content/2012/06/s3534237.htm?site=&source=rss Reasons why Asbestos Poses such a Threat According to the unions asbestos has killed more Australians than World War 2, with mesothelioma, pleural disease and asbestosis being the most dangerous of the side effects. Here we discuss each of these diseases associated with asbestos poisoning. Mesothelioma is another type of cancer that could occur as a result of asbestos exposure. It is cancer of the pleura and may only occur 20 to 40 years after the exposure occurs. This disease grows and spreads quickly before the symptoms appear which makes early diagnosis and treatments harder. The average survival time after diagnosis is only 6-18 months. A very small exposure to asbestos can be enough to trigger the cancer, however only a small percentage of people exposed to asbestos develop mesothelioma.
  • 3. Pleural disease is another dreaded disease associated with asbestos. This is when the outer lining of the lung, called the plura becomes irritated and inflamed. This outer lining then stiffens and thickens and can become filled with liquid, which can hamper normal breathing and restrict oxygen intake. Asbestosis is when lungs become scarred causing airways to become inflamed and scarred, retricting the flow of oxygen to the lungs and into the blood. The lungs become stiff and inelastic, making breathing more difficult. Symptoms include tightness in the chest, dry cough, and in the later stages, a bluish tinge to the skin caused by lack of oxygen. Asbestosis is usually seen in former asbestos miners, asbestos manufacturing workers and insulation workers. The scariest part about this disease is that it can take up to 10 years for symptoms to show up, which makes diagnosing harder.

  • 4. Most Common Injuries on Construction Sites Some of the most common causes of injury on a construction site involves falling hazards, electrical hazards, working with cranes and machinery and working from scaffolding. Falling Hazard The most common occurrence of incidents on construction sites involve workers falling according to statistics provided by authorities. This type of hazard also causes the most serious injuries. Extreme caution must be administered when working from a height, especially a height higher than 2 meters. Workers need to be aware of your surroundings and take note and caution of slippery boards on scaffolds and walkways, missing guardrails, openings in floors and penetrations that are not correctly protected. Report all openings or missing railings so they can be corrected as soon as possible. Relating to the hazard of falling is the issue of scaffolding work. When work from heights cannot be eliminated, the use of scaffolding is necessary. To comply with the applicable scaffolding regulations, all persons erecting or altering scaffold must be competent and certified to do so. All scaffolds must be erected in compliance with statutory regulations and such scaffold and accessories must conform to regulations. Any damaged planks must be removed, kickboards must be secured in place and guardrails installed. Mobile scaffolds present their own hazards, in that they are frequently used and must be erected as per regulations. They should be fitted with wheel locks which must be in place whenever people are working on the scaffold so that it doesn’t roll causing a fall. All scaffolds should have an internal ladder for access. Climbing of scaffolding standards should not be allowed and tools and equipment should not be left lying around unattended on scaffolds as they tripping hazard they present can be compounded by a fall from a height. Personal Protective Equipment is the form of Safety helmets must be worn at all times when working from a scaffold. Workers must be provided with a safety helmet which must be worn at all times.
  • 5. Electrical Hazard The occurrence of electrocutions on construction sites is a prevalent danger that requires attention. This is a hazard that can be minimised if workers follow the correct safety and preventative procedures as most cases of electrocution are caused by a form of negligence. As far as electrical installations are concerned on sites a qualified electrician must carry out all repairs to equipment and electrical installations, including repair and replacement. The basic rules to remember are to keep electrical leads off the ground and on stands and do not hang leads from scaffolding. Do not use double adaptor fittings or overload adaptors. Replace all damaged leads, wiring, equipment or installation and report faults immediately. During rainy weather covers must be provided for equipment exposed to the elements, if covers cannot be provided then equipment must not be used as electrocution can result. Workers should not touch wires or cords that they are unfamiliar with especially if they don’t know whether it is live or not. Explosive-Powered Tools The very nature of this tool makes it a hazard. These tools use an explosive charge to fire fixings into concrete, steel and timber, and, like a firearm and therefore they are potentially lethal. These can only be operated by trained persons, who are wearing the correct safety glasses and hearing protection. Signs must be placed in the area of operation of this equipment to warn passers-by of the danger they present. These tools should not be left unguarded and especially not in a loaded condition. All explosive-powered tools must be inspected and maintained on a regular basis as all machinery should be. They should be locked away when not in use, they are dangerous and are a loaded weapon in the wrong hands. Cranes Just last week another worker was crushed by a crane on a construction site. This occurrence is only too common of late. It is important that only authorised certificated operators will be permitted to operate cranes. Crane Operators and Doggers must work in close terms with each other, each should know what the other is doing, and they need to co-operate and communicate in order to avoid dangerous situations. Crane Doggers should be directing crane operators only. Irresponsible behaviour m,ust be avoided such as riding the load which is strictly prohibited. Slings, ropes and chains are to be checked on a daily basis and monitored for any signs of wear. Workers must keep their hands clear of pinch points and away from slings on loads, as they can easily become caught. Loads must be correctly slung and workers should never stand under loads, this is another reason workers get crushed by the load. Crane and mobile machinery operators must check clearance of electrical power lines when setting up or operating as the danger of electrocution is very prevalent. Any defects with cranes, machinery and associated gear must be reported to those in charge immediately.
  • 6. By following a few simple rules, workers on construction sites can minimise the risks associated with this dangerous work. White Card and Site specific training is the most important tools in the arsenal of construction employers in ensuring that their workers are aware of the hazards and know how to respond to them successfully.

  • 7. White Card Update: Trench and Excavation Safety All construction industry workers are aware that the industry is one that holds many dangers as well as many rewards. In order to succeed in this dynamic and ever changing industry, workers need to value safety above all else. One of the major hazards construction workers face is presented by Trenching and Excavation. Although workers will receive the necessary training, we will refresh workers with the basics in this post. In order to work safely in the vicinity of trenches or excavations employers and employees need to identify hazards associated with trenching and excavation work, assess risks and eliminate or minimise those risks before, during and after the performance of work. Prior to commencement of work a site investigation should be carried out, in which as much information as possible is obtained about the ground conditions. The duty of an employer according to WH&S legislation is to provide safe systems of work, instruction, training and supervision to ensure that employees are safe from injury. When deciding on a system of ground support for an excavation or trench consider the nature of the ground, weather conditions an proximity of in-ground services. Employers who ignore this step often find themselves in the middle of incidents that result in injury. Examine the area where the work is to be carried out, conduct a risk assessment and implement appropriate control measures. Excavations of more than 1.5 metres in depth require an engineer to assess the site conditions and prepare an engineer’s report which will be used to implement safety control measures. Many factors can influence the stability of trenches or excavations. These include static and dynamic loads, including the spoil pile, adjacent buildings, ground vibration and wet or dry conditions. Safe systems of work must be used to ensure the conditions at the site are safe. The site must be left in a safe condition when work is not in progress. Inspection should be carried out daily in order to ascertain that the trench or excavation is stable. This includes surveillance of trench walls, support systems and excavations should be carried out frequently and recorded. During these inspections the following should be observed:
  • 8. both the trench and excavation walls are not undercut.  supports are not overstressed.  ground is not fretting or beginning to collapse.  look out for tension cracks along the trench or excavation surface.  the trench or excavation walls do not sag under the increased pressure from plant or equipment. Persons should not work alone in a trench due to the danger involved. Workers in the vicinity of the trench must wear the appropriate PPE, including hard hats, safety boots, safety vests, safety glasses and gloves. The appropriate equipment should be determined as part of the risk assessment. Signage and barricades are also important around the hazardous area to warn workers and others of the dangers of the hazard. It is important for construction workers to remember the golden rule of any Confined Space including trenches and excavations: Do not attempt to enter a confined space unless you are fully trained and know what you are doing! Confined space entry and exits are a particularly important area to address. Tunnels, shafts and trenches present a major safety hazard and the importance of having entry and exit openings that are large enough for a properly equipped person to pass through should be understood. The size and number of openings also have an impact on the ventilation. Confined space entry is a specialised field and requires training and thorough understanding of the appropriate work and safety products. Workers entering a confined space should be trained in: • The nature of hazards associated with confined spaces • Necessary precautions that need to be taken • Proper use of PPE • Emergency case procedures • Personnel must be adequately trained in rescue and first aid • Follow defined entry procedures – Steps for working in Trenches, Excavations Or other confined spaces: 1. Perform a review determining whether working in the space is absolutely necessary 2. Consider substituting work with less hazardous work activities 3. Gain authority to enter the confined space 4. Ensure all workers wear PPE 5. Ensure engineering controls are in place to separate other workers from the hazard
  • 9. 6. Determine if there is a need to set up additional training, maintain supervision, develop rosters and do whatever is reasonably necessary to ensure safety in the confined space. 7. By working together and keeping communication open workers and employers can ensure safety when working in confined spaces is upheld.

  • 10. Tragedy Hits Construction Site - Worker crushed by Crane An incident in The USA recently has cast a dark cloud over the use of cranes in construction. A crane operator was killed when the crane he was operating collapsed, trapping him in the cabin for over 5 hours. A report by Abclocal.go.com had this to say: A construction worker who was using a crane to lift a large cement wall was killed after that crane collapsed. It happened at the old Garden Ridge on I-45 near The Woodlands which was destroyed by an arsonist last October. Crews worked all afternoon to lift the large crane from its side. The operator had been trapped in the machine's cab for several hours. It's a disturbing image of a crane toppled over that had a group of worried spectators watching and waiting several hours for help at a construction site near The Woodlands. Sgt. Joe Smart with the Conroe Police Department said, "It looks like it pinned the cab where the operator sits under the weight of the crane." Emergency workers who rushed to the scene couldn't immediately rescue the crane operator, who has been identified as Luis Ruiz. Police say the man was among a group of contractors on this site rebuilding the Garden Ridge that burned down last year. Deena Nicholson of The Woodlands said, "It's really, really sad. It just seems like help is taking so long." Eyewitnesses told police something just went wrong. "It looks like he was lifting one of these concrete walls to begin construction of this building, and I'm told it was the first wall of the new building," said Sgt. Smart. The crane operator was trapped inside the cab for nearly five hours before help finally arrived. Police say they were waiting for large trucks and heavy equipment to lift the machine. As for the crane operator, sadly investigators say this accident appears to be tragic. Family members tell me the operator's been in construction for about 40 years. They call him a devoted husband and father.
  • 11. OSHA investigators are on the scene. Source: http://abclocal.go.com/ktrk/story?section=news/local&id=8718021 Sadly it is too late for this operator and his family but other operators on construction sites around Oz do not need to suffer the same fate. No matter how dangerous crane work may be, workers can minimise the risk involved by being alert and complying with safety regulations. A crane is a powerful tool used for shifting heavy loads to and from a vehicle. Many fatalities have occurred where workers were crushed by cranes, either when the load shifts unexpectedly or a malfunction occurs. Employers have a responsibility to ensure that they provide a safe work environment, safe systems of work and plant and substances are in a safe condition. Any operator needs to be certified to do so and be in possession of appropriate certificates of competency for Crane operation and Dogging. Employers must ensure that a hazard identification and risk assessment is carried out and that safe systems of work are implemented as control measures for all operations. They must also ensure that all crane operators are qualified and certified to operate the cranes. Operators must also be trained in the safe operation procedure for the crane being used. Another problematic area is when operators accidentally bump levers causing unintended movements. Controls should be clearly and permanently marked and all bump bars/guards should be installed around the controls to prevent this inadvertent lever operation which can often prove fatal. Operators carry great responsibility and need to be aware of the danger zones on site that is the areas where the operator may be hit by the load or the boom section of the crane and avoid entering the danger zones while operating the crane. Operators are also responsible for monitoring the load stability and adhere to the manufacturer’s instructions in operating the crane. Problems may arise from load slinging. These situations can be controlled successfully by consulting with the workers and planning safe work strategies. As with all risks on construction sites, the hazards of cranes can be controlled and managed to avoid injury with a little planning by employers. Operators can assist by remaining alert behind the control and remembering their safety training whenever they are at the controls.
