The basic idea of an over current (think of overcurrent as current out of control) protection device is to create a weak link in the system that will stop the flow of electricity before the overcurrent can cause any other damage. Overcurrent protection devices should always be placed on the hot leg and sized appropriately. Improper sizing can cause wiring or equipment to be damaged before the protection device has a chance to do its job. These devices may not and are not intended to protect people; they protect equipment.
Power extension cords and power strips (also known as power taps) are a means to deliver electricity from a power source to a tool or device located where the power source is not. Sometimes the use of such power delivery devices presents overloading factors. The possible consequences of using a power strip should be considered beforehand. Some concerns include Damaged or faulty devices posing fire and shock hazards Tripping hazards Rules to follow: Extension cords are authorized only for temporary use (to do the job at hand, not to remain as a power source for an extended amount of time (days, weeks). Extension cords may not be run through doorways, windows, ceilings, etc. whereby they may be damaged and/or pose tripping hazard Extension cords may not be smaller in diameter then the tool power cords to which they are connected Power strips are authorized only for temporary use, if they are to be used as extension cords Power strips designated as TVSS may be used for longer periods of time for electronic devices only (computers and components, adding machines, clocks, radios) but should not be overloaded or doubled-up Power strips and extension cords may not be used for appliances (refrigerators, microwaves, coffee pots, portable heaters) All devices and cords must be UL or comparably approved and in good working condition without any signs of damage
If you encounter an EGI extension cord that is missing or has a damaged ground prong. Take out of service immediately by cutting off the male end and delivering to the EGI Supervisor
As a rule.., these items are not allowed on any EGI project.
For our purposes today, the client is Middlesex Hospital. But this also applies to all other jobsites.
EEW pertains to qualified electrical workers. They must attend additional and more extensive training than provided in this section. This does not apply to anyone attending the New Employee Orientation Training.
Do not take shortcuts and risk the safety of yourself or others. Know and follow safe work practices and procedures, and if you are unsure…ASK!! Use only appropriate tools and equipment for the work to be done. Inspect all tools and equipment prior to and during work activity. The label UL Approved only means the device left the factory meeting certain criteria. During the time that you may use the device, it may become damaged, therefore exposing yourself and others to hazards. Remember: stray electric current caused by damage to a device can shock, seriously injure or kill. Report any and all unsafe conditions: Receiving an electric shock Sparks Overheating or smoking equipment; Corroded/damaged outlets, switches and junction boxes; Damaged extension cords and equipment power cords that are in use; Exposed wiring, broken plugs, outlets, missing box cover or faceplates; Outlets in damp areas not equipped with GFCI. Stay productive and safe - follow the rules .
