29 CFR 1910.1200,
Arkansas Act 556 of 1991
"The purpose of this law is to provide
public employees access to training
and information concerning
hazardous chemicals in order to enable
them to minimize their exposure to
any hazardous chemicals and protect
their health, safety and welfare."
Almost every day we encounter chemicals,
whether it be cleaning the bathroom,
filling your vehicle with gasoline,
applying pesticides or insecticides
or using solvents or acids at work or home.
Many chemicals will cause injury
or illness if not handled properly.
Hazard Communication is better
known as the "Right to Know" law.
"Right to Know"
OSHA created the Hazard Communication
Standard to help ensure your safety
when working with hazardous chemicals.
You have a RIGHT TO KNOW about
the hazardous chemicals you use on the job
and how to work safely with those chemicals.
Chemical manufacturers must:
Determine a chemical’s hazards,
provide labeling of such hazards,
and provide MSDS's for these chemicals.
Post adequate notice to inform employees of their rights.
Ensure proper chemical labeling.
Maintain and make material safety data sheets available.
Compile and maintain a workplace chemical list for
hazardous chemicals used, generated or stored
in amounts of 55 gallons or 500 pounds or more.
Provide employees with information and training.
Read the labels and the MSDSs,
follow instructions and warnings,
identify hazards before starting a job,
and participate in training.
Types of Hazards:
Physical Hazards are flammability, explosiveness,
Health Hazards are corrosiveness and toxicity.
Routes of Entry:
Chemical Exposure, skin and eye contact,
ingestion (swallowing), inhalation,
and penetration (skin absorption).
All routes can provide for a dosage
that can cause acute or chronic effects.
Personal Protective Equipment (PPE):
Gloves, aprons, dust masks, glasses, goggles, and face shields.
Hazardous Materials First Aid:
Skin; Wash thoroughly with soap and water.
Eyes; Flush with water for 15 minutes, holding eyelids open.
Inhalation; Move to fresh air, get medical assistance.
Swallowing; Get emergency medical assistance, do not induce
vomiting unless directed to do so by quailified personnel.
Spills and Leaks:
Evacuate the immediate area,
notify a supervisor or proper personnel,
remove any ignition sources (if safe to do so),
stay away, and ensure other people
don't inadvertantly enter the area.
Provides the identity of the chemical,
name, address, and emergency phone
number of the manufacturer;
gives the physical and health hazards
and any special handling instructions;
provides information for basic
and has guidance for first aid,
fire response, and spill cleanup.
All lab instructors and lab prep personnel
who prepare unknown samples for labs
MUST label the unknown
the course name, the lab experiment number,
a descrete identification, and the date,
(ex; CHEM 2134, exp#10, unk. A, 8/21/03)
and MUST provide this
to the chemical hygiene officer.
NFPA Labeling Systems:
NFPA = National Fire Protection Association
Blue = Health
Red = Flammability
Yellow = Reactivity
White = Other hazards or special handling
Scale: 0 (No Hazard) to 4 (Extreme Hazard)
Material Safety Data Sheet Program:
By law, a MSDS must be provided for
any chemical purchased or transfered,
Reading an MSDS can often be difficult,
there is no standard for MSDS's,
and it is often written for worst case scenario,
and large bulk amounts (railroad car volumes).
MSDS's for McEver are located in
each lab that contains chemicals,
and with the Chemical Hygiene Officer
(CHO), Rm 24, McEver.
Finding a specific MSDS:
Each faculty member that teaches a laboratory
that contains chemicals must be aware of the
MSDS binder location for that room,
and should include this as part of
their lab indroctrination for the students.
If a new chemical is used in the lab,
that MSDS should be included in the local binder.
If a MSDS can not be found,
contact the CHO, one will be provided.
Informatin that can be found
in a Material Safety Data Sheet:
Chemical and manufacturer identity.
Physical and chemical characteristics.
Fire, explosion, and reactivity.
Routes of entry.
Exposure levels (PEL or TLV).
Symptoms of exposure.
First-Aid and emergency information.
Personal Protective Equipment (PPE).
Safe handling and storage.
Spills and leaks.
