1. Annual Refresher Training

2. The Federal OSHA Standards, 29 CRF 1910 and 1926,
better known as the “Hazard Communications” or
“Right-to-Know” standards, apply to the state
government and its political subdivision.

3. Material Data Safety Sheet
(MSDS)
MSDS of a chemical describes the physical
and chemical properties, physical and
health hazards, routes of exposure,
precautions for safe handling and use,
emergency and first aid procedures, and
control measures.
Each workplace is required to have MSDS
available for every single hazardous
chemical or substance you use or
encounter as part of your job.

4. Hazardous Substance
OSHA has classified chemicals that
have the potential to cause acute
or chronic health effects as
“health hazards.” These include:
 Carcinogens – formaldehyde
 Corrosives – phenol
 Hepatotoxins – chloroform
 Mutagens – ethidium bromide
 Neurotoxins – acrylamide
 Teratogens - formamide

5. Material Data Safety Sheet
(MSDS)
At a minimum the MSDS are required to have
the following:


Section I. Chemical Identity
Section II. Hazardous Ingredients
Section III. Health Hazards
Section IV. First Aid Measures

Section VI. Accidental Release Measures
Section VII. Precautions for Safe Handling and Use
Section VIII. Control Measures

6. Material Data Safety Sheet
Chemical Product & Company Information
MSDSs must be in English and include
the following information:
 The identity of the material, including the
identity on the label, the chemical and
common name(s), and the Chemical
Abstract Service Registry (CAS) number(s)
 The name, address, and telephone number
of the manufacturer, importer, employer, or
other responsible party who can provide
additional information or assistance for
emergency procedures, or as otherwise
necessary.

Stability and Reactivity
Disclosure of potential reactivity hazards is
required in an MSDS. This is often
accomplished by describing the conditions that
could result in a potentially hazardous
chemical reaction.
The following information could be included:



Chemical stability
Conditions to avoid
Incompatibility with other materials
Hazardous decomposition products
Hazardous polymerization.

8. Material Data Safety Sheet
Hazard Identification
Potential Health Effects
Exposure to the material and its components
during customary and reasonably foreseeable
use, misuse, handling, and storage. It must
include the following elements:








Relevant route(s) or exposure
Lengths of exposure
Severity of the effect
Target organ(s)
Type of effect
Signs and symptoms of exposure
The chemical carcinogenicity status
Medical conditions known to be aggravated by
the exposure to the material.

9. Material Data Safety Sheet
Hazard Identification
First Aid Measures
Instructions on providing immediate treatment before
professional medical help is available. It should also
indicated whether immediate medical attention is required
and if delayed effects can be expected after exposure.
When there is no specific information available, the
following information may be included:


Removal of exposed individuals from the area
Removal of material from the individual
Advice on removal and handling of contaminated clothing
and shoes
Advice on whether immediate medical attention is
necessary.

Properties of both flammable and nonflammable materials
that may initiate or uniquely contribute to the intensity of a
fire
Potential for dust explosion
Reactions that release flammable gases or vapors
Fast or intensely burning characteristics
Release of invisible flammable vapors.

11. Material Data Safety Sheet
Hazard Control
Accidental Release Measures
This section contains information for
responding to spills, leaks, or releases in order
to eliminate or minimize the adverse effects on
persons, property, and the environment.
The following types of information should be
included:



Containment techniques (e.g., diking or capping
procedures)
Cleanup procedures (e.g., neutralization and
decontamination techniques, sorbent materials,
sweeping or vacuuming techniques)
Equipment and other emergency advice relating
to spills and releases.

12. Material Data Safety Sheet
Hazard Control
Exposure Controls/Personal Protection
This section of the MSDS will include
information on the controls necessary to
help reduce the risk of personnel exposure,
including:
 Guidance for the selection of PPE for each
route of exposure, and for the use of special
PPE (e.g., SCBAs) in the event of an
emergency
 Engineering controls (e.g., local exhaust
system) to minimize potential airborne
contaminants
 Work practices to reduce the possibility of
contact or exposure.

13. Material Data Safety Sheet
Additional Information
 The MSDS includes the preparation date of the document,
the last change to it, the OSHA Permissible Exposure Limits
(PELs), ACGIH Threshold Limit Values (TLVs), and any
other recommended exposure limit, if available.

14. Toxicology Terms
Acute toxicity:
Chronic toxicity:
•Single short exposure
• Repeated exposure
•Effects usually appear quickly
• Effects usually delayed
•Effects often reversible
• Usually irreversible
 LD 50: In tests for lethality, the dose at which 50% of
the test animals are killed, usually expressed in mg./kg.
 LC 50: For for inhalation hazards, usually expressed in
mg./m.3

15. Toxicology Signal Words
Toxicity Rating

A taste (less than 7 drops)
Highly Toxic
5 to 50 mg/Kg
7 drops to 1 teaspoon
Moderately

16. Labeling and Marking Systems
In addition to the
manufacturer’s labels,
which are provided on
most chemical products,
there are also the:
 National Fire Protection
Association (NFPA) diamonds
 Hazard Assessment Signage
Program (HASP) system
Always read the labels provided on the
products
you use!!!

17. NFPA Diamonds
A NFPA diamond is
located on the door
of the storage room.
Blue = Health Hazard
Red = Flammability
Yellow = Instability
White = Special Hazard
Information

18. HASP Signage
Laboratories should be marked with
the appropriate pictographic
symbols to warn employees,
visitors, and emergency
responders what hazards to
expect upon entering the
laboratory, as well as what
precautions should be observed

20. All Done!
Make sure you fill out the quiz, sign it, and drop it
off in my mailbox for record keeping.
