Scope and Application
This program applies to all employees of who may
be exposed to hazardous chemicals in a manner
inconsistent with normal consumer use. The
HazCom Program provides you with the necessary
information and resources needed to ensure you
are aware of the hazards associated with
hazardous materials located and/or used within
your work place. Elements of this program are
designed to communicate to employees all safety
related information about hazardous chemicals
used in their work environment. Knowledge of
hazardous materials is key to preventing over
exposures, work-related illnesses, and chemical
accidents.

Material Safety Data Sheets THE KEY TO CHEMICAL
HAZARD INFORMATION
MSDS
  • MSDS must be on file for all hazardous materials
    before allowed into use.
  • New substances must be pre-approved for use.
  • New uses of approved substances should be
    approved.

18
Example MSDS
19
Hazardous Chemical Locations
  • Hazardous Chemical List For Facility
  • Consult MSDS Index for complete listing of all
    hazardous chemicals and location
  • Drums
  • Processes

  • (e.g. gloves, acid suit, face shield for
    acid transfers)
  • Ensure appropriate controls are functioning
  • (e.g. exhaust hood is on when present)
  • Use the substance in a manner consistent with its
    labeling.
  • Treat all chemicals with respect.
  • Never use a chemical unless you know the hazards
    associated with its use and the protective
    measures to be taken.

21
Detecting Releases
  • Company conducts monitoring when conditions
    warrant. May be done in-house or by outside
    consultant depending on circumstances
  • Unusual work area conditions should be
    communicated to supervisor or safety engineer
    immediately
  • POSSIBLE RELEASE INDICATORS
  • Unusual odors
  • Smoke or visible haze
  • Abnormally high absenteeism rate
  • Employees sick more than normal
  • Dead or dying plants, vegetation or local animals
  • Neighborhood complaints
  • Unusual smell from sewers
  • Sound of escaping gas or steam

22
Detecting Releases
  • Physical Changes Noted In Your Body or Behavior
    May Also Signal Exposure or Over-Exposure to a
    Hazardous Substance and You Should Seek Medical
    Attention if
  • Unusual Taste In Mouth or Discolored Tongue or
    Lips
  • Skin or Eye Irritation or Rash
  • Difficulty Breathing, Seeing or Hearing

Health Toxicology
  • Two Types of Health Affects
  • Acute Short-Term effects on body. Symptoms
    develop immediately or shortly after exposure.
    Effect is usually of short duration.
  • Chronic Long-Term effects on body resulting
    from repeated low level exposures with symptoms
    developing slowly over a period of time.
  • Examples Drunkenness is the acute effect from
    overindulgence in alcohol. Liver brain damage
    are chronic affects.
  • Smoking Acute Wheezing, Shortness of Breath
  • Chronic Lung Cancer,
    Emphysema

34
Exposure Limits
  • Developed to protect you from adverse health
    effects, both acute and chronic. Two main types
  • PEL Permissible Exposure Limits determined by
    OSHA for which the majority of persons can be
    exposed to for 8 hours a day, 40 hours a week,
    without experiencing any adverse health effects.
    See OSHA Z-Tables.
  • TLV Threshold Limit Values established by the
    American Conference of Governmental Industrial
    Hygienists (ACGIH). Recommended Exposure Limits.
    PELs take precedent over TLVs.
  • Both types usually expressed as concentration or
    mass per unit volume (ug/m3).
  • PELs have ceiling limits - Can Not Exceed Ever
  • TLVs and PELs have STELs - 15 minute Short Term
    Exposure Limits
  • Use MSDS recommendations in absence of PEL/TLV

35
Toxic Effects
  • Based on Actual Case Studies and Animal
    Experiments That Are Extrapolated to Infer
    Expected Effects on Humans
  • LD50 Lethal Dose of chemical substance in which
    50 of the test animals are expected to die from
    oral, dermal, or absorption routes of exposure.
    Expressed in milligrams per kilograms of the
    animal tested.
  • LC50 Lethal Concentration of chemical substance
    in which 50 of the test animals are expected to
    die from exposure to airborne concentrations.
    Expressed in units of weight, milligrams or
    micrograms, per volume of air, usually cubic
    meters and specifies time period, usually 1 or 4
    hours.

36
Toxic Effects
  • Corrosive Liquid or solid that causes visible
    destruction or irreversible alterations in human
    tissue. Usually thought of as a Physical Hazard.
  • Examples Acids, Flux, Caustics, Hydroxides,
    Ammonia
  • Irritant Inflammatory response of eye, skin or
    respiratory system
  • Examples Smoke, Dusts, Almost all Chemical
    Vapors
  • Sensitizer Can become sensitized after just one
    exposure if you are susceptible. Skin
    sensitization is most common form.
  • Examples Isocyanates used in Plastics and
    Resins
  • Neurotoxin Capable of causing neurological
    damage to the central nervous system, usually
    only after long-term over exposures.
  • Examples Many Solvents

37
Toxic Effects
  • Teratogen Of concern to women. Compound or
    agent capable of causing malformations of fetus
    skeleton and soft tissues.
  • Examples Mercury/Cerebral Palsy Lead PCBs
  • Mutagen Compound or agent capable of causing
    genetic and chromosomal damage resulting in
    mutations capable of being passed on from
    generation to generation.
  • Examples Lead Ionizing Radiation
    Ultra-Violet Light
  • Carcinogen Compound or agent capable of causing
    cancer.
  • Example Benzene (Component of gasoline)
  • Example Cadmium Metal Fumes (Lead is a
    suspected carcinogen)
  • Example Formaldehyde
