water); 2 (materials that are unstable but do not detonate or which can react
violently with water); 3 (materials that can detonate when initiated or which can
react explosively with water); 4 (materials that can detonate at normal
temperatures or pressures).
NATIONAL FIRE PROTECTION ASSOCIATION: Health Hazard: 0
(material that on exposure under fire conditions would offer no hazard beyond
that of ordinary combustible materials); 1 (materials that on exposure under fire
conditions could cause irritation or minor residual injury); 2 (materials that on
intense or continued exposure under fire conditions could cause temporary
incapacitation or possible residual injury); 3 (materials that can on short
exposure could cause serious temporary or residual injury); 4 (materials that
under very short exposure could cause death or major residual injury).
Flammability Hazard and Reactivity Hazard: Refer to definitions for
Hazardous Materials Identification System .
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 le thal 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 inhalati on
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
Resea rch 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
Administr ation; 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.
