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 Regulations. |
