HAZARDOUS MATERIALS IDENTIFICATION SYSTEM HAZARD
RATINGS:
PHYSICAL HAZARD (continued): 2 Water Reactivity: Materials that may react violently with
water. Organic Peroxides: Materials that, in themselves, are normally unstable and will readily
undergo violent chemical change, but will not detonate. These materials may also react violently
with water. Explosives: Division 1.4 explosives. Explosive substances where the explosive effects
are largely confined to the package and no projection of fragments of appreciable size or range
are expected. An external fire must not cause virtually instantaneous explosion of almost the
entire contents of the package. Compressed Gases: Pressurized and meet OSHA definition but <
514.7 psi absolute at 21.1°C (70°F) [500 psig]. Pyrophorics: No Rating. Oxidizers: Packing Group
II oxidizers. Solids: any material that, either in concentration tested, exhibits a mean burning time
of less than or equal to the mean burning time of a 2:3 potassium bromate/cellulose mixture and
the criteria for Packing Group I are not met. Liquids: any material that exhibits a mean pressure
rise time less than or equal to the pressure rise of a 1:1 aqueous sodium chlorate solution
(40%)/cellulose mixture and the criteria for Packing Group I are not met. Reactives: Substances
that may polymerize, decompose, condense, or self-react at ambient temperature and/or
pressure, but have a low potential (or low risk) for significant heat generation or explosion.
Substances that readily form peroxides upon exposure to air or oxygen at room temperature. 3
Water Reactivity: Materials that may form explosive reactions with water. Organic Peroxides:
Materials that are capable of detonation or explosive reaction, but require a strong initiating
source or must be heated under confinement before initiation; or materials that react explosively
with water. Explosives: Division 1.3 explosives. Explosive substances that have a fire hazard and
either a minor blast hazard or a minor projection hazard or both, but do not have a mass
explosion hazard. Compressed Gases: Pressure ≥ 514.7 psi absolute at 21.1°C (70°F) [500 psig].
Pyrophorics: No Rating. Oxidizers: Packing Group I oxidizers. Solids: any material that, in either
concentration tested, exhibits a mean burning time less than the mean burning time of a 3:2
potassium bromate/cellulose mixture. Liquids: any material that spontaneously ignites when
mixed with cellulose in a 1:1 ratio, or which exhibits a mean pressure rise time less than the
pressure rise time of a 1:1 perchloric acid (50%)/cellulose mixture. Unstable Reactives:
Substances that may polymerize, decompose, condense, or self-react at ambient temperature
and/or pressure and have a moderate potential (or moderate risk) to cause significant heat
generation or explosion. 4 Water Reactivity: Materials that react explosively with water without
requiring heat or confinement. Organic Peroxides: Materials that are readily capable of detonation
or explosive decomposition at normal temperature and pressures. Explosives: Division 1.1 & 1.2

Unstable Reactives: Substances that may polymerize, decompose, condense, or self-react at
ambient temperature and/or pressure and have a high potential (or high risk) to cause significant
heat generation or explosion.
