FLAMMABILITY LIMITS IN AIR:
Much of the information related to fire and explosion is derived from the
National Fire Protection Association (NFPA). Flash Point
- Minimum
temperature at which a liquid gives off sufficient vapors to form an ignitable
mixture with air. Autoignition Temperature
: The minimum temperature
required to initiate combustion in air with no other source of ignition. LEL
-
the lowest percent of vapor in air, by volume, that will explode or ignite in the
presence of an ignition source. UEL
- the highest percent of vapor in air, by
volume, that will explode or ignite in the presence of an ignition source.
TOXICOLOGICAL INFORMATION:
Possible health hazards as derived from human data, animal studies, or from
the results of studies with similar compounds are presented. Definitions of
some terms used in this section are: LD
50 - Lethal Dose (solids & liquids)
which kills 50% of the exposed animals; LC
50 - Lethal Concentration (gases)
which kills 50% of the exposed animals; ppm concentration expressed in parts
of material per million parts of air or water; mg/m
3
concentration expressed in
weight of substance per volume of air; mg/kg quantity of material, by weight,
administered to a test subject, based on their body weight in kg. Other
measures of toxicity include TDLo, the lowest dose to cause a symptom and
TCLo the lowest concentration to cause a symptom; TDo, LDLo, LDo, TC,
TCo, LCLo, and LCo, the lowest dose (or concentration) to cause lethal or
toxic effects. BEI - Biological Exposure Indices, represent the levels of
determinants which are most likely to be observed in specimens collected from
a healthy worker who has been exposed to chemicals to the same extent as a
worker with inhalation exposure to the TLV. Ecological Information: EC is
the effect concentration in water.
Data from several sources are used to evaluate the cancer-causing potential of
the material. The sources and ratings are: IARC - the International Agency
for Research on Cancer; 1 = Carcinogenic to humans, 2A, 2B = Probably
carcinogenic to humans, 3 = Unclassifiable as to carcinogenicity in humans,
and 4 = Probably not carcinogenic to humans. NTP - the National
Toxicology Program; K =Known to be a human carcinogen, and R =
Reasonably anticipated to be a human carcinogen. RTECS - the Registry of
Toxic Effects of Chemical Substances. OSHA - Occupational Safety and
Health Administration and CAL/OSHA - California’s subunit of the
Occupational Safety and Health Administration; Ca = Carcinogen defined with
no further categorization. ACGIH – American Conference of Governmental
Industrial Hygienists; A1 = Confirmed human carcinogen, A2 = Suspected
human carcinogen, A3 = Confirmed animal carcinogen with unknown
relevance to humans, A4 = Not classifiable as a human carcinogen, and A5 =
Not suspected as a human carcinogen. NIOSH – U.S. National Institute for
Occupational Safety and Health; Ca = Potential occupational carcinogen, with
no further categorization. EPA – U.S. Environmental Protection; A = Human
carcinogen, B = Probable human carcinogen, C = Possible human
carcinogen, D = Not classifiable as to human carcinogenicity, E = Evidence
of Non-carcinogenicity for humans, K = Known human carcinogen, L =
Likely to produce cancer in humans, CBD = Cannot be determined, NL =
Not likely to be carcinogenic in humans, and I = Data are inadequate for an
assessment of human carcinogenic potential.
REGULATORY INFORMATION:
This section explains the impact of various laws and regulations on the
material. EPA is the U.S. Environmental Protection Agency. WHMIS is the
Canadian Workplace Hazardous Materials Information System. DOT and TC
are the U.S. Department of Transportation and the Transport Canada,
respectively. Superfund Amendments and Reauthorization Act (SARA); the
Canadian Domestic/Non-Domestic Substances List (DSL/NDSL); the U.S.
Toxic Substance Control Act (TSCA); Marine Pollutant status according to the
DOT; the Comprehensive Environmental Response, Compensation, and
Liability Act (CERCLA or Superfund); and various state regulations. This
section also includes information on the precautionary warnings that appear on
a material’s industrial package label.
