1 - does not increase burning rate
2 - moderate increase in burning rate
3 - severe increase in burning rate
4 - can undergo explosive reaction that severely increases burning rate
✔✔Personal supervision - ✔✔supervision by the holder of any certificate of fitness who
is required to be personally present on the premises , or other proximate location
acceptable to the department, while performing the duties for which the certificate is
required
✔✔Physical hazard - ✔✔a chemical for which there is evidence that it is a combustible
or flammable liquid; a flammable solid or gas; an explosive; an organic peroxide; an
oxidizer; a pyrophoric material; an unstable (reactive) material; a water-reactive solid or
liquid; or a cryogenic liquid

spontaneously at a temperature at or below 130F
, ✔✔Reduced flow valve - ✔✔a valve equipped with a restricted flow orifice and inserted
into a compressed gas container that is designed to reduce the maximum flow from the
valve under full flow conditions

pressure (NTP)
✔✔Storage cabinet - ✔✔a cabinet for the storage of flammable and combustible liquids
✔✔Unstable (Reactive) Material - ✔✔material, other than an explosive, that will
vigorously polymerize, decompose, condense, or become self-reactive and undergo
other violent changes, when exposed to heat, friction, or shock.
Divided into 4 classes, increasing level of hazard 1-4
✔✔Unstable (reactive) material classes - ✔✔Classes 1-4

✔✔Water-reactive material - ✔✔A material that has a dangerous chemical reaction
when reacting with water. May explode, violently react, produce flammable, toxic, or
other hazardous gases, and/or generate enough heat to cause ignition of the material or
nearby materials.
Divided into 3 classes, increasing level of hazard 1-3
