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:
Human and Animal Toxicology: 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. Human and Animal Toxicology (continued): Other measures of toxicity include
TDLo, the lowest dose to cause a symptom and TCLo the lowest concentration to cause a symptom;
TDo, LDLo, and LDo, or TC, TCo, LCLo, and LCo, the lowest dose (or concentration) to cause lethal
or toxic effects. Cancer Information: The sources are: IARC - the International Agency for Research
on Cancer; NTP - the National Toxicology Program, RTECS - the Registry of Toxic Effects of
Chemical Substances, OSHA and CAL/OSHA. IARC and NTP rate chemicals on a scale of decreasing
potential to cause human cancer with rankings from 1 to 4. Subrankings (2A, 2B, etc.) are also used.
Other Information: BEI - ACGIH 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.
REPRODUCTIVE TOXICITY INFORMATION:
A mutagen is a chemical that causes permanent changes to genetic material (DNA) such that the changes
will propagate through generational lines. An embryotoxin is a chemical that causes damage to a
developing embryo (i.e. within the first eight weeks of pregnancy in humans), but the damage does not
propagate across generational lines. A teratogen is a chemical that causes damage to a developing fetus,
but the damage does not propagate across generational lines. A reproductive toxin is any substance that
interferes in any way with the reproductive process.
ECOLOGICAL INFORMATION:
EC is the effect concentration in water. BCF = Bioconcentration Factor, which is used to
determine if a substance will concentrate in lifeforms which consume contaminated plant or
animal matter. TL
m
= median threshold limit; Coefficient of Oil/Water Distribution is
represented by log K
ow
or log K
oc
and is used to assess a substance’s behavior in the
environment.
