Hazard Communication& Chemical Safety
Based on OSHA Standard
1910.1200
We use many chemicals…
We want you to know how to use them safelyYou will learn about…
The Hazards of Chemicals Our Written Program How Chemicals are Labeled Safe Use of Chemicals Material Safety Data Sheets Basic Procedures for Spills Who you can ask for more information
Hazards of Chemicals…
There are 2 basic types of chemical hazards Physical Hazards Health Hazards
The first rule of Chemical safety is… "Know what you are working with and how to protect yourself and others“
Physical Hazards…
Chemicals are classified as having Physical Hazards if they are
Explosive Compressed Gas Combustible Liquids Flammable Unstable Water Reactive Oxidizers
Physical Hazards…
Some chemicals may be safe by themselves, but become dangerous when in contact with other substances.
Chemicals with Physical Hazards…
Used only by trained employees
Stored in a safe manner Never mixed with other
chemicals unless by an approved procedure
Health Hazards
Chemicals are classified as being a health hazard if they: Can cause cancer Are poisonous (toxic) Cause harm to your skin, internal
organs, or nervous system Are corrosive - such as acids Cause allergic reactions after
repeated exposure
Chemicals can enter the body through:
your lungs if you breath fumes, mists or dust
your skin if liquid or dust touches or spills on you or splashes in your eyes
your mouth if you eat after handling chemicals
accidental swallowing of a chemical
Health Effects…
Some chemicals affect specific organs such as your kidneys, liver, reproductive or nervous system.
Our Written Hazard Communication Program
provides…Written information on hazardsLists Chemicals we use and their
hazardsSystem for ensuring chemicals are
labeledMeans to ensure we have an
Material Safety Data Sheet (MSDS) for each chemical
Our Written Hazard Communication Program…
Lists who is responsible for the program
Provides chemical specific safety training methods
Tells you where to find chemical safety information
You can see a copy of our written program by asking you supervisor
Labeling of Chemicals…Chemical Labels provide
information on Identity, Hazards and Safe Use
All chemical containers are labeled by the manufacturer
Our company may place additional labels on the containers
Labeling of Chemicals…
If chemicals are placed in another container, this new container must have a a label placed on it.
All containers must be properly labeled
Uniform Labeling System…
Our Company “Uniform Labels” are used to ensure we have one labeling system.
These may be placed on containers
when chemicals are delivered to us or chemicals are transferred to other containers
2 Basic “Uniform Labels”
HMIS - Hazardous Material Identification System
NFPA - National Fire protection Association
Both types must identify thechemical name and hazards
Uniform Labels…
Pictures may be used to identify hazards and required protection
This Information may also be on the Manufacturer’s label
HMIS & NFPA labels are very similar
Both use colored boxes to identify specific hazards
Numbers or codes in the boxes tell you the hazard value
higher numbers = higher hazard
NFPA & HMIS Label Colors
Red - Fire HazardBlue - Health Hazard
YellowYellow - Reactivity Hazard - explosive, unstable
WhiteWhite - Special Hazards - corrosive, radioactive, water reactive, acid
NFPA Label..The purpose of the NFPA 704 labeling system is to provide a way of quickly identifying the various fire related hazardous associated with a particular material. The NFPA 704 "diamond" is commonly found on bulk storage containers, but is also widely used on chemical containers and MSDS sheets.
NFPA Flammability Codes4 Materials that will rapidly or
completely vaporize at atmospheric pressure and normal ambient temperature, or that are readily dispersed in air and that will burn readily. Liquids with a flashpoint below 73ºF and a boiling point below 100ºF.
NFPA Flammability Codes
3 Liquids and solid that can be ignited under almost all ambient temperature conditions. Liquids with a flashpoint below 73ºF and a boiling point above 100ºF or liquids with a flashpoint above 73ºF but not exceeding 100ºF and a boiling point below 100ºF.
NFPA Flammability Codes
2 Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur. Liquids with flashpoint above 100ºF but not exceeding 200ºF.
NFPA Flammability Codes
1 Materials that must be preheated before ignition can occur. Liquids that have a flashpoint above 200ºF.
0 Materials that will not burn.
NFPA Health Hazard Codes
4 Materials that on very short exposure could cause death or major residual injury.
3 Materials that on short exposure could cause serious temporary or residual injury.
NFPA Health Hazard Codes
2 Materials that on intense or continued, but not chronic exposure could cause incapacitation or possible residual injury.
NFPA Health Hazard Codes
1 Materials that on exposure would cause irritation but only minor residual injury.
0 Materials that on exposure under fire conditions would offer no hazard beyond that of ordinary combustible material.
NFPA Reactivity Hazard Codes
4 Materials that in themselves are readily capable of detonation or of explosive decomposition or reaction at normal temperatures and pressures.
NFPA Reactivity Hazard Codes
3 Materials that in themselves are capable of detonation or explosive decomposition or reaction but require a strong initiating source or which must be heated under confinement before initiation or which react explosively with water.
NFPA Reactivity Hazard Codes
2 Materials that readily undergo violent chemical change at elevated temperatures and pressures or which react violently with water or which may form explosive mixtures with water.
NFPA Reactivity Codes
1 Materials that in themselves are normally stable, but which can become unstable at elevated temperatures and pressures.
NFPA Reactivity Codes
0 Materials that in themselves are normally stable, even under fire exposure conditions, and which are not reactive with water.
NFPA Special Hazard CodesACID = Acid ProductsALK = Alkali or BasesCOR = Corrosive ProductsOX = OxidizerW =Reacts with water Radioactive
What do I do…
if there is no label or I cannot read the label?
STOP - do not use the chemicalTELL your supervisorREAD the MSDS and have another
label put on the container
Chemicals can be safely used if…
you know the hazards and how to protect yourself
they are used only for approved purposes
they are stored properlyyou use the correct personal protective equipment
Chemicals can be safely used if…
you do not eat in areas where chemicals are used
you wash immediately if you come in contact with chemicals
Chemical Disposal…
Each chemical and container must be disposed of properly
No container is truly "empty" unless properly cleaned
Follow MSDS requirements for container disposal
Chemical Disposal…
Recycle unused chemicals
Do not place hazardous chemicals in normal trash receptacles.
Do not pour chemicals into sinks, onto the ground or in storm drains
Safe Storage…
Store incompatible chemicals in separate areas
Limit the amount of flammable material to the minimum needed
Store flammable liquids in approved flammable storage lockers
Safe Storage…
Store acids in separate flammable storage lockers
Do not store chemicals in a refrigerator used for food storage
Do not store food in refrigerators used for chemical storage
In case of an emergency…
Implement the proper Emergency Action Plan
Evacuate people from the areaIsolate the area- keep other from
enteringTurn off ignition and heat sourcesOnly trained employees are
permitted to clean up spills
Material Safety Data Sheets (MSDS)
Show chemical safety informationEach chemical has a separate MSDSMSDS is written by the chemical
manufacturerMSDS are kept in the workplace for
your useIf you can't find an MSDS, ask
your supervisor
Material Safety Data Sheets…
are provided by the chemical manufacturer to provide additional information concerning safe use of the product.
Each MSDS tells you…
1. Common Name and Chemical Name of the material
2. Name, address and phone number of the manufacturer
3. Emergency phone numbers for immediate hazard information
4. Date the MSDS was written
MSDS…
5. Hazardous ingredients6. Physical & Health Hazards of the
chemicals7. Identification of chemical and
physical properties8. First Aid / Emergency Information9. Safe handling and use information

Protecting Yourself…
Personal Protective Equipment (PPE) may be needed to protect yourself from chemical hazards
Use the PPE our Company has required for each chemical
Check the PPE before use to make sure it is not damaged
Protecting Yourself…
Use face shield and Goggles if there is a splash hazard
Use the proper respirator for dusts, mists and fumes
Protecting Yourself…
Use the right gloves when handling chemicals
Properly clean and store your PPE after use
Don't take PPE home - why risk exposing your family?
Stay safe when using chemicals…
Know what you are working withKnow where MSDS are located and
how to use themAsk your supervisor if you have
questionsOnly trained employees may use
chemicals
Stay Safe…Make sure all containers
are properly labeledUse the proper protective
equipmentStore chemicals only in
approved areasImmediately report leaks
and spillsDispose of used chemicals
and containers properly
