AMMO 18 CORRECT A EXAMS ANSWERS AND
QUESTIONS SET A+
✔✔Which safeguards ensure the safety of ammunition items? Select all that apply -
✔✔Fuze mechanism is physically disconnected from the detonator until the round is
fired
Fuzes are stored and shipped separately from the ammunition item
✔✔How are low explosives primarily used in ammunition? - ✔✔As a propellent to fire
the projectile out of a weapon
✔✔Class 1: Explosives - ✔✔Division 1
HC/D 1.1
Examples: ammunition, fireworks, flares, blasting caps, fuses, primers, gunpowder, and
explosive charges. Hazard Class 1 has 6 divisions, which will be covered later in the
lesson.
✔✔Class 2 : Compressed Gases - ✔✔Flammable gases - acetylene, butane, hydrogen
HC/D 2.1
Non-flammable, non-poisonous gases - helium, nitrogen, and neon HC/D 2.2
Poisonous gases - chlorine, ammonia anhydrous, carbon monoxide HC/D 2.3
✔✔Class 3: Flammable Liquids - ✔✔Hazard Class 3 represents flammable liquids that
ignite at a specific flash point. A flash point is the temperature at which a material gives
off enough vapors to ignite. HC 3 does not have any divisions.
Examples: aviation fuel (JP 8), gasoline, alcohol, acetone, toulene, paint, kerosene,
turpentine, and other industrial solvents
✔✔Class 4: Flammable Solids - ✔✔Flammable solids that catch fire easily - safety or
strike-anywhere matches HC/D 4.1
Spontaneously combustible materials (may catch fire without a separate heat source) -
charcoal briquettes, linseed oil HC/D 4.2
Water-reactive materials (may ignite or emit flammable gas when in contact with water)
- potassium, sodium, MRE heaters HC/D 4.3
, ✔✔Class 5: Oxidizers & Organic Peroxides - ✔✔Oxidizers can generate oxygen and
may cause other materials to combust. Organic peroxides contain oxygen and may
ignite on their own.
Oxidizers - ammonium nitrate fertilizer, hydrogen peroxide HC/D 5.1
Organic peroxides - methyl ethyl ketone peroxide HC/D 5.2
✔✔Class 6: Toxic & Infectious Materials - ✔✔Toxic materials - potassium cyanide,
arsenic HC/D 6.1
Biohazards - medical waste, virus cultures HC/D 6.2
✔✔Class &: Radioactive Materials - ✔✔Hazard Class 7 represents radioactive materials
and has no divisions.
Examples: uranium, plutonium, iridium, americium, and thorium
**Any time you receive or ship radioactive materials, you must coordinate it through
your Radiation Safety Officer (RSO).
✔✔Class 8 Corrosive Materials - ✔✔Hazard Class 8 represents corrosive materials and
has no divisions.
Examples: sulfuric acid, hydrochloric acid, nitric acid, odium hydroxide, formaldehyde,
flux, chlorides, and iodine
✔✔Class 9: Miscellaneous Hazardous Materials - ✔✔Hazard Class 9 represents
miscellaneous hazardous materials and has no divisions.
Examples: asbestos, airbag inflators, lithium ion batteries, magnets, polystyrene beads
dry ice (when transported by air or vessel), and cotton (when transported by land or
vessel)
✔✔Identifying Hazard Classes - ✔✔The hazard class(es) for any HAZMAT being stored
or transported is found on the shipping papers, package labels, vehicle placards, and
NALC Data Sheet
✔✔HC/D 1.1 - ✔✔Mass explosion hazard - bombs and 155mm projectiles
✔✔HC/D 1.2 - ✔✔Fragmentation hazard - fuzes and 20mm cartridges
✔✔HC/D 1.3 - ✔✔Fire hazard - propellant, artillery charges
✔✔HC/D 1.4 - ✔✔Moderate fire hazard - small arms ammunition, smoke or flash-bang
grenades
✔✔HC/D 1.5 - ✔✔Very insensitive explosives - blasting agents
There are currently no Navy explosives classified as HC/D 1.5
