MSDS = Material Safety Data Sheet
• The MSDS lists the
chemical ingredients of
the substance.
• Some list only the
dangerous chemicals,
while others list every
ingredient, even if the
chemical is not
hazardous.
The Purpose of a MSDS is to tell you….
•
•
•
•
•
•
Material’s Physical Properties
Health Hazard Data
Fire and Explosion Data
Reactivity Data
Spill & Leak Procedures
Special Protection Information &
protective gear needed
• Special Precautions /
How to respond to accidents.
• Company Info
for phone # of emergency contacts
Who Supplies MSDS to Product Users?
All manufacturers of
hazardous chemicals are
required to provide one
of these sheets for all
products which they sell

Your Employee Rights
& Student Rights
• Your employer must have an MSDS for every
hazardous substance that you use as part of your
job
• These MSDS’s must be available to you in the
workplace
• If you request to see a copy of an MSDS for a
product you use and it is not provided in 1 working
day, then you may refuse to work with the product
in the area that it is used
• If requested, your employer must provide a
personal copy of an MSDS within 15 working days
Labeling and Marking Systems
• All chemical containers must be labeled
• Acceptable systems include
– NFPA-704 diamonds (National Fire
Protection Agency)
– HMIS labels (Hazardous Materials
Identification System)
– Manufacturer’s original label
– Other
Labeling and Marking Systems
NFPA-704 Diamonds
• Color coded &
numerical rating system
• Provide at-a-glance
hazard information

HEALTH
4 Deadly: Slightest exposure to this substance
would be life threatening. Only specialized
protective clothing should be worn.
3 Extreme Danger: Serious injury from exposure to
this substance. Do not expose any body surface
to these materials. Follow full protective
measures.
2 Dangerous: Exposure would be hazardous to
health. Protective measures indicated.
1 Slight Hazard: irritation or minor injury would
result from exposure to this substance. Protective
measures are indicated.
0 No Hazard: exposure to this substance offers no

Very Flammable, volatile or explosive depending
on its state: Flash Point below 73ºF & Boiling Point
below 100ºF. Extreme caution should be used in
handling or storing of these materials.
Flammable, volatile or explosive under normal
temperature conditions: Flash Point Below 100ºF.
Exercise great caution in storage or handling.
Moderately heated conditions may ignite this
substance: Flash Point Below 200ºF. Caution in
handling.
Combustible, must be preheated to ignite: Flash
Point Above 200ºF. Most combustible solids fit this
category.
Will Not Burn

May Detonate: capable of detonation or explosion at
normal temperatures and pressures. Evacuate area if
exposed to heat or fire.
Explosive: capable of detonation or explosion by a
strong initiating source, such as heat, shock or water.
Monitor from behind explosion-resistant barriers.
Unstable: violent chemical changes are possible at
normal or elevated temperatures and pressures.
Potentially violent or explosive reaction may occur
when mixed with water. Monitor from a safe distance.
Normally Stable: may become unstable at elevated
temperatures and pressures or when mixed with
water. Approach with caution.
Stable: remain stable when exposed to heat, pressure
or water.
