HAZMAT PLACARD QUESTIONS AND ANSWERS
This placard or label is used to designate explosive materials, specifically Class 1.1, 1.2
and 1.3 explosives
Mass Explosive Hazard, i.e., Black Dynamite
Consists of explosives that have a projection hazard but not a mass explosion hazard,
e.g., flares
Consists of explosives that have a fire hazard and either a minor blast hazard or a minor
projection hazard or both but not a mass explosion hazard, e.g, rocket motors
, Consists of explosives that present a minor explosion hazard. The explosive effects are
largely confined to the package and no projection of fragments of appreciable size or
range is to be expected, e.g., practice ammo
Consists of very insensitive explosives. This division is comprised of substances which
have a mass explosion hazard but are so insensitive that there is very little probability of
initiation or of transition from burning to detonation under normal conditions of transport,
prilled ammonium nitrate
Consists of extremely insensitive articles which do not have a mass explosive hazard.
This division is comprised of articles which contain only extremely insensitive detonating
substances and which demonstrate a negligible probability of accidental initiation or
propagation
Flammable gases, e.g., propane, acetylene
