Definitions and other useful data:
CAS #: The
Chemical Abstract Service Number which uniquely identifies each
constituent.
ACGIH -
American Conference of Governmental Industrial Hygienists, a
professional association which establishes exposure limits.
TLV -
Threshold Limit Value - an airborne concentration of a substance
which represents conditions under which it is generally believed
that nearly all workers may be repeatedly exposed without adverse
effect.
OSHA -
U.S. Occupational Safety and Health Administration.
PEL -
Permissible Exposure Limit - The same value as a TLV, except it is
enforceable by OSHA.
IDLH -
Immediately Dangerous to Life and Health - A concentration from
which one can escape within 30-minutes without suffering permanent
injury.
NATIONAL
FIRE PROTECTION ASSOCIATION:
Health Hazard Rating Scale (Blue):
0 (material that on exposure under fire conditions would offer no
hazard beyond that of ordinary combustible materials);
1 (materialsthat 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 Rating Scale (Red):
0 (minimal hazard);
1 (materials that require substantial pre-heating before burning);
2 (combustible liquid or solids; liquids with a flash point of
38-93°C [100-200°F]);
3 (Class IB and IC flammable liquids with flash points below 38°C
[100°F]);
4 (Class IA flammable liquids with flash points below 23°C [73°F]
and boiling points below 38°C [100°F].
Reactivity Hazard Rating Scale(Yellow):
0 (normally stable);
1 (material that can become unstable at elevated temperatures or
which can react slightly with 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).
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:
LD50 -Lethal Dose (solids & liquids) which kills 50% of the exposed
animals;
LC50 - 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/m3 concentration expressed in weight of substance per volume of
air;
mg/kg quantity of material, by weight.
REGULATORY
INFORMATION:
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, which assign DOT and TDG (Transportation of Dangerous
Goods) identification numbers, hazard classifications, and proper
shipping name and shipping label information. This material is
hazardous as defined by 49 CFR 172.101 of the US Department of
Transportation and Dangerous Goods as defined by Transport Canada
Transportation of Dangerous Goods Regularions. |
