NATIONAL FIRE PROTECTION ASSOCIATION HAZARD
RATINGS (continued):
FLAMMABILITY HAZARD (continued): 1 Materials that must be preheated before ignition can
occur. Materials in this degree require considerable preheating, under all ambient temperature
conditions, before ignition and combustion can occur: Materials that will burn in air when exposed to a
temperature of 816°C (1500°F) for a period of 5 minutes in accordance with Annex D. Liquids, solids and
semisolids having a flash point at or above 93.4°C (200°F) (i.e. Class IIIB liquids). Liquids with a flash
point greater than 35°C (95°F) that do not sustain combustion when tested using the Method of Testing for
Sustained Combustibility, per 49 CFR 173, Appendix H or the UN Recommendation on the Transport of
Dangerous Goods, Model Regulations (current edition) and the related Manual of Tests and Criteria
(current edition). Liquids with a flash point greater than 35°C (95°F) in a water-miscible solution or
dispersion with a water non-combustible liquid/solid content of more than 85 percent by weight. Liquids
that have no fire point when tested by ASTM D 92 Standard Test Method for Flash and Fire Points by
Cleveland Open Cup, up to a boiling point of the liquid or up to a temperature at which the sample being
tested shows an obvious physical change. Combustible pellets with a representative diameter of greater
than 2 mm (10 mesh). Solids containing greater than 0.5 percent by weight of a flammable or combustible
solvent are rated by the closed up flash point of the solvent. Most ordinary combustible materials. 2
Materials that must be moderately heated or exposed to relatively high ambient temperatures before
ignition can occur. Materials in this degree would not under normal conditions form hazardous
atmospheres with air, but under high ambient temperatures or under moderate heating could release
vapor in sufficient quantities to produce hazardous atmospheres with air: Liquids having a flash point
at or above 37.8°C (100°F) and below 93.4°C (200°F) (i.e. Class II and Class IIIA liquids.) Solid
materials in the form of powders or coarse dusts of representative diameter between 420 microns (40
mesh) and 2 mm (10 mesh) that burn rapidly but that generally do not form explosive mixtures in air.
Solid materials in fibrous or shredded form that burn rapidly and create flash fire hazards, such as
cotton, sisal and hemp. Solids and semisolids that readily give off flammable vapors. Solids containing
greater than 0.5 percent by weight of a flammable or combustible solvent are rated by the closed cup
flash point of the solvent. 3 Liquids and solids that can be ignited under almost all ambient temperature
conditions. Materials in this degree produce hazardous atmospheres with air under almost all ambient
temperatures or, though unaffected by ambient temperatures, are readily ignited under almost all
conditions: Liquids having a flash point below 22.8°C (73°F) and having a boiling point at or above
37.8°C (100°F) and those liquids having a flash point at or above 22.8°C (73°F) and below 37.8°C
(73°F) and below 37.8°C (100°F) (i.e. Class IB and IC liquids). Materials that, on account of their
physical form or environmental conditions, can form explosive mixtures with air and are readily
dispersed in air. Flammable or combustible dusts with a representative diameter less than 420 microns
(40 mesh). Materials that burn with extreme rapidity, usually by reason of self-contained oxygen (e.g.
dry nitrocellulose and many organic peroxides). Solids containing greater than 0.5 percent by weight
of a flammable or combustible solvent are rated by the closed cup flash point of the solvent. 4 Materials
that will rapidly or completely vaporize at atmospheric pressure and normal ambient temperature or
that are readily dispersed in air and will burn readily: Flammable gases. Flammable cryogenic
materials. Any liquid or gaseous materials that is liquid while under pressure and has a flash point
below 22.8°C (73°F) and a boiling point below 37.8°C (100°F) (i.e. Class IA liquids). Materials that
ignite when exposed to air, Solids containing greater than 0.5 percent by weight of a flammable or
combustible solvent are rated by the closed cup flash point of the solvent.
INSTABILITY HAZARD: 0 Materials that in themselves are normally stable, even under fire
conditions: Materials that have an estimated instantaneous power density (product of heat of reaction and
reaction rate) at 250°C (482°F) below 0.01 W/mL. Materials that do not exhibit an exotherm at temperatures
less than or equal to 500°C (932°F) when tested by differential scanning calorimetry. 1 Materials that in
themselves are normally stable, but that can become unstable at elevated temperatures and pressures:
Materials that have an estimated instantaneous power density (product of heat of reaction and reaction rate)
at 250°C (482°F) at or above 0.01 W/mL and below 10 W/mL. 2 Materials that readily undergo violent
chemical change at elevated temperatures and pressures: Materials that have an estimated instantaneous
power density (product of heat of reaction and reaction rate) at 250°C (482°F) at or above 10 W/mL and
below 100W/mL.
3 Materials that in themselves are capable of detonation or explosive
decomposition or explosive reaction, but that require a strong initiating source or that must
be heated under confinement before initiation: Materials that have an estimated instantaneous
power density (product of heat of reaction and reaction rate) at 250°C (482°F) at or above 100
W/mL and below 1000 W/mL. Materials that are sensitive to thermal or mechanical shock at
elevated temperatures and pressures. 4 Materials that in themselves are readily capable of
detonation or explosive decomposition or explosive reaction at normal temperatures and
pressures: Materials that have an estimated instantaneous power density (product of heat of
reaction and reaction rate) at 250°C (482°F) of 1000 W/mL or greater. Materials that are sensitive
to localized thermal or mechanical shock at normal temperatures and pressures.
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.
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

ow
or

and is used to assess a substance’s behavior in the
environment.
