Hazard Communications
Your “Right to Know”
Every American has the right to know the
chemicals to which they may be exposed in
their daily living. Right-to-Know laws provide
information about possible chemical
exposures.

Environmental Health and Safety
Material Safety Data Sheets:
Your Rights

Your employer must have an MSDS for
every hazardous substance you use as
part of your job.
 If you ordered the chemical, it is your
responsibility to obtain the MSDS and file
it in the MSDS binder in your area.

These MSDS’s must be available to
you the entire time you are in the
workplace.
 Storage in a locked office, filing cabinet, or
computer inaccessible by those using the product
is a violation of the law.
Environmental Health and Safety
Material Safety Data Sheets:
Your Rights

If you request to see a copy of an
MSDS for a product you use, and your
employer cannot provide it; after one
working day, you may refuse to use
that product or work in an area where it
is being used.
If you request your own personal copy
of an MSDS, your employer has 15
days to provide it.

Health Hazard Data
• LC50 or LD50 is the amount of material needed to
kill 50% of the test organisms. The lower the
LC50 or LD50 the more toxic the material
Environmental Health and Safety
Health Hazard Data Acronyms
• LC50 or LD50 (lethal concentration or dose 50).
• TLV (threshold limit value) • the level of exposure that most workers can experience
without unreasonable risk of disease or injury.
• STEL (short term exposure limit)
• TWA (time weighted average)
• acceptable exposure over 8 hr work shift.
• PEL (permissible exposure limit)
• Maximum exposure limit
• C (ceiling) - maximum concentration never to be
exceeded at any time.
The smaller the number, the more toxic
the material!

Environmental Health and Safety
Hazardous chemicals in the
workplace

Corrosives
 Low or high pH that will burn skin. Name usually
contains “acid” or “hydroxide”

Flammables
 Produce enough vapor to burn at temperatures
below 100oF

Toxics
 OSHA defines toxic as a material with an LC50 of
50-5000mg/kg, highly toxic as LC50 less than
50mg/kg
 Everything can kill you. The dose makes the
poison.
Environmental Health and Safety
Hazardous Chemicals in the
Workplace continued

Carcinogens
 Cause cancer
 OSHA does not give a safe exposure level
for carcinogens. Avoid exposure.

Mutagens
 Disrupt the genetic code

Teratogens
 Harm the developing fetus
Environmental Health and Safety
Methods to Detect Release

Use your senses
 Is there a strong or unusual odor?
 Do you see a pool of liquid, a broken jar?
 Does a jar contain less material though it hasn’t
been used?
 Do you hear something dripping?
 Do you feel something slippery, slimy, dusty etc?
Caution! Some compounds do not have good
warning properties. You cannot see or smell
them even at dangerous concentrations. Air
monitoring must be done.
Environmental Health and Safety

Recognizing Tasks Resulting in
Exposure

Are you creating dust?
 Sweeping, pouring powder


Are you using a solvent with a high
vapor pressure without ventilation?
Does your process release fumes or
mist?
Environmental Health and Safety
Physical and Health Hazards

Acute - damage done after short exposure.
Usually a large dose.
 Dizziness, nausea, vomiting, burns, poisoning,
etc.

Chronic - damage done after long term
(lifetime) exposure at low dose.
 Cancer, multiple sclerosis, memory impairment,
etc.
Environmental Health and Safety
Physical and Health Hazards

Mutagens 
alter male and female DNA in sex cells that are
transferred to the child.
 More damaging to women as a woman carries all
the eggs she will ever have from childhood.
Sperm are regenerated constantly and have a
short lifespan. May result in sterility, birth defects

Teratogens  only dangerous to the developing fetus. Caution
must still be exercised in women of childbearing
age as pregnancy can be unknown for the first two
or three weeks after conception, and the majority
of contraceptives are not fail-safe.
 Both may cause birth defects or miscarriage.
Environmental Health and Safety
Routes of Chemical Exposure

Inhalation
 By breathing dust or fume

Absorption
 solvents easily penetrate the skin carrying other
compounds dissolved in solvent

Ingestion
 failure to wash hands after work.

Injection
 picking up contaminated broken glass with bare
hands
Environmental Health and Safety
Personal Protective Equipment
(PPE)

Glasses/ Goggles
 Face shields may be used with chemical goggles when
significant splash hazards exist. They may not be used
alone.
 Laser work, welding, and glass work require lenses to
block the specific infrared wavelengths of light
 Impact goggles are required when cutting, drilling,
sanding, grinding or performing other operations where
flying objects could enter the eye.

Impact goggles have little holes on the side
 Chemical splash goggles are required when working with
chemicals which could damage the eye.

Environmental Health and Safety
Chemical goggles have indirect vents. NEVER use
impact goggles as chemical splash protection!
PPE continued

Gloves
 One glove material will not protect you from all hazards.
 Check a chemical compatibility chart like
http://www.labsafety.com/refinfo/ezfacts/
click on “Chemical compatibility for gloves”

Respirators
 Anyone can use the white fiber N-95 dust masks. They
only reduce exposure to dust. There is no chemical
protection offered by them.
 Half or full rubber masks should only be used when
engineering controls are not adequate (I.e. fume hoods,
fans, spray booths) and require fit testing.
 Contact Kathy Rogers to be included in the respiratory
protection plan. (x5946)


Clothing
 Aprons, closed toed or steel toed shoes, no
bare midriffs, etc.
