Hazardous Materials
Chemical Inventory
Each area must maintain a
complete, accurate and up to
date chemical inventory.
 The inventory should include:

– All Chemicals
 Hazardous
 Non-hazardous
– Compressed Gasses
Chemical Inventory

When you are doing the inventory, it is a
good time to discard any chemicals that:
– Are expired.
– Are no longer being used.
– Have containers that have been compromised,
i.e. Cracked lid.
– Have labels that are illegible.

Submit your updated inventory to EH&S on
the yearly basis.
Material Safety Data Sheets - MSDS

A Material Safety Data
Sheet or MSDS is
information provided by
the manufacturer and
maintain by the employer
to inform employees of the
possible hazards
associated with chemicals
being used in their work
area. It is part of a hazard
communication program.
Material Safety Data Sheets - MSDS
Each area must maintain a current
MSDS for each chemical or compound
being stored or used in the shop/studio.
 Each MSDS must be available whenever
the chemical is being used.
 Everyone should know how to use and
understand MSDS’s and where they are
located.

Important MSDS Information

Chemical Id

Synonyms

Hazardous Ingredients


Exposure Limits

Physical Data

Health Hazards
Toxic, Carcinogen, etc.

Physical Hazards
Corrosive, Oxidizer, etc.

Wear appropriate PPE


Headache, Nausea, etc.
Important MSDS Information

An MSDS is a good source to determine:
– Proper Personal Protective Equipment (PPE).
– Labeling requirements.
– Storage requirements.

READ an MSDS before using a new
chemical or unsure of the possible
hazards.
MSDS
Emergency
In an emergency and you cannot retrieve an
MSDS, you can be obtained it by calling the 3E
Company’s 24 Hour phone #:
800-451-8346
Or
760-602-8703
Chemical Storage

Separate incompatible chemicals.
– Separate oxidizers from flammables (Solvents, Paints)
– Separate flammable liquids, acids and bases
Provide earthquake restraints for all shelving
when storing chemicals or glassware.
 Secondary containment needs to be provide if
there is a risk of a release into the environment.

Chemical Storage

The storage container MUST be compatible
with material it is holding.
– Example: Metal containers cannot be used for
acids and bases.

Food containers MUST NEVER BE USED!
No earthquake restraints!
Flammable Liquids Storage
If a area has quantities
greater than 10 gallons, they
must be stored in an
approved flammable liquids
storage cabinet.
 Containers that can be
shattered or punctured easily
must be in secondary
containment.
 Do not store flammables with
acids or bases.

Acids Storage
Store in secondary containment
 Label cabinets “Acid” with 3” letters
 Store acids of different classes in separate
secondary containment

– Organic (Acetic Acid)
– Inorganic (Hydrochloric Acid)
– Oxidizing (Nitric Acid)
Bases Storage
Store in secondary containment
 Store away from acids and solvents
 Label cabinets “Base” with 3” letters
 Examples

– Hydroxides
– Ammonia
– Bleach
Compressed Gasses Storage

Must be upright and restrained
– At least two chains

Separate incompatible gasses
– Flammable & Oxidizing by 20 feet

Keep caps on while in
transportation or in storage
Chemical Labeling

All containers in the studio must be
properly labeled with the name of the
material being stored in the container.
This includes non-hazardous materials
such as:
– Water
– Dyes
– Aqueous Salt Solutions

Full name with “no” abbreviations.
Chemical Labeling

Containers of hazardous materials must
not only include the name of the material
but also the physical and health hazards
associated with the use of the material.
Chemical Labeling

Consult the MSDS or the manufacturer’s
label for accurate labeling information
regarding physical and health hazards.
HMIS
“Hazardous Materials
Identification System”
The HMIS rating is a color-coded, alphanumeric system which gives information
about the health, flammability and reactivity of the chemical in question. The
system rates a material from a minimal hazard through a serious hazard. It also
recommends the appropriate personal protective equipment to be worn when
handling the particular chemical.
Example of HMIS
HMIS Health










0 - Minimal Hazard
Not significant risk to health.
1 - Slight Hazard
Irritation or minor reversible injury possible.
2 - Moderate Hazard
Temporary or minor injury may occur.
3 - Serious Hazard
Major injury likely unless prompt action is taken and medical treatment is given.
4 - Severe Hazard
Life-threatening, major or permanent damage may result from single or repeated over exposures.
HMIS Flammability










0 - Minimal Hazard
Materials that will not burn. Usually includes any material that will not burn in air when exposed
to a temperature of 1500°F. for a period of 5 minutes
1 - Slight Hazard
Materials that must be preheated before ignition can occur.
2 - Moderate Hazard
Materials that must be moderately heated or exposed to relatively high ambient temperatures
before ignition can occur.
3 - Serious Hazard
Materials capable of ignition under almost all ambient temperature conditions.
4 - Severe Hazard
Materials that will rapidly or completely vaporize at atmospheric pressure and normal ambient
temperatures with a flashpoint below 73°F. Materials may ignite spontaneously with air.
HMIS Reactivity




0 - Minimal Hazard
Materials that are normally stable even under fire conditions.
1 - Slight Hazard
Materials that are normally stable but that can become unstable at elevated temperatures and
pressures.
2 - Moderate Hazard
Materials that readily undergo violent chemical change at elevated temperatures and pressures.
These materials may also react violently with water.
3 - Serious Hazard
Materials that are capable of detonation or explosive decomposition but require a strong initiating
source or materials the react explosively with water.
4 - Severe Hazard
Materials that are readily capable of detonation or explosive decomposition or explosive reaction
at normal temperatures and pressures.

Frequently Asked Questions

Q. How do I know what is the appropriate
Personal Protective Equipment (PPE) that I
should use?

A. Check the MSDS or sometimes the
manufacture’s label will have the information.
MSDS’s are a great tool in deciding how to label
your containers, too.
Frequently Asked Questions

Q. Do I need to use the blue, red, yellow and
white HMIS labels?

No, it would be ideal if everyone did but
sometimes it is not practical. You can use
whatever method you can. Be it masking tape or
sharpies. As long as all the information is there,
it is legible and stays on the container, you are
fine.
Frequently Asked Questions

Q. Why do I need to label something has just
plain water in it?

A. A container with water looks just like a
container with Hydrochloric Acid or any other
clear liquid. You can’t tell if something is
dangerous just by looking at it. That is the
purpose of Hazard Communication.
Communicate what is hazardous and what is
not.
