Chemical manufacturers or importers shall ensure that distributors
and employers are provided an appropriate material safety data
sheet with their initial shipment, and with the first shipment after a
material safety data sheet is updated;
The employer shall maintain in the workplace copies of the required
material safety data sheets for each hazardous chemical, and shall
ensure that they are readily accessible during each work shift to
employees when they are in their work area(s). (Electronic access,
microfiche, and other alternatives to maintaining paper copies of the
material safety data sheets are permitted as long as no barriers to
immediate employee access in each workplace are created by such
options.)

Chemical Toxicology
Toxicology is the study of how chemicals
cause undesirable effects on humans.
Signs and Symptoms of Exposure



Know the signs and symptoms associated
with exposure to the chemicals in your
workplace.
Be observant for these signs and symptoms.
Know what to do if you are exposed.
Chemical Toxicology
Routes of Entry




Inhalation
Absorption
Ingestion
Injection
Chemical Toxicology
Inhalation


The most common route of exposure.
Can be in the form of a gas, vapor or dust.
Example: Formaldehyde


Can be deposited in the airways or absorbed
through the lungs and into the blood stream.
Blood can then circulate the toxin to the rest
of the body.
Chemical Toxicology
Absorption


Skin acts as a barrier between the
environment and the organs of the human
body.
Skin can be attacked directly.
Examples: Acids and Bases

Skin can be penetrated.
Examples: Phenol, Nitrobenzene
Chemical Toxicology
Ingestion



Rarely takes place by deliberate swallowing of
toxic substances.
Food and drinks can become contaminated
by dust, mist and fumes.
Dust on hands, face and clothing can get into
the mouth by licking one’s lips or wiping one’s
face.
Chemical Toxicology
No eating or drinking
in laboratories or
storing food in
laboratory
refrigerators or cold
rooms.
Chemical Toxicology
Injection


Occurs through accidental needle sticks,
puncture wounds or through broken skin /
open wounds.
May produce rapid response when injected
because the chemical / toxin is introduced
directly into the blood stream.

either air changes per
hour (ACH) cubic feet
per minute (cfm).
Local Ventilation
A local source of
ventilation is used
over equipment that
may give off a gas,
fume or dust. Similar
to a fan over a stove
to remove smoke
from cooking food.
Fume Hood

local exhaust used for
working with chemicals
that have the potential to
give off fumes. dust or
gases. Fume hoods
should be check for
operability, sash height
and annual certification
prior to use.

biological agents to
protect the researcher
from the agent. Filters
airborne contaminants
before exhausting air.

Refrigerator
•Do not store flammables in a
standard refrigerator.
•Do not store food, beverages
or ice for human consumption
in refrigerators.

a warning label about not
storing food in it.
Minimizing waste generation
Order only the amount of chemical
required for the experiment.
Excessive stocks of hazardous chemicals,
radioactive material and infectious agents
presents serious storage, safety and
disposal problems.
Try to find non-hazardous alternatives to
conduct your research.
Waste Types
Hazardous: chemicals
Medical: items contaminated with
biological agents, toxin, blood or
body fluids
Universal: florescent lights,
computers and monitors
Radioactive: P-32, C-14, Uranium
Identifying Waste
Proper laboratory waste disposal begins at
the experimental design stage.
When evaluating the experiment to be
performed consider the types of waste that
will be generated in procedure.
If in doubt ask your Principal Investigator
or laboratory supervisor
Contact EH&S for assistance
Satellite Accumulation Area

transferring waste to container
Containers must be stored within a
designated secondary container
Must be at or near the point of generation
and under the control of the trained person
directly responsible for the waste.
Container Management

waste that is stored in it.
Incompatible containers must be
segregated.
Containers must be in good condition, not
ruptured or leaking.
Container Labeling
All containers must be labeled with a
UMASS DARTMOUTH Hazardous waste
