AMMO 67 UPDATED EXAM SCRIPT QUESTIONS AND
ANSWERS GRADED A+
✔✔Hazard class knowledge - ✔✔As a HAZMAT employee, knowing the hazard class
and what they are capable of doing allows you to safety transport or store hazardous
materials.
First responders must know the hazard class to correctly respond to the type of
emergency (gas, liquid, explosive, etc.) With this information, they can safely control
and contain a HAZMAT accident and protect the public.
✔✔What could happen when hazardous materials that react dangerously when in
contact with each other are transported together? - ✔✔Possible Hazards
Because of the nature of hazardous materials, if they come in contact with each other,
they are capable of producing other hazards
i.e. when bleach and ammonia come in contact with each other, they produce a toxic
vapor (which is an inhalation hazard).
✔✔Hazard Class Division - ✔✔Some hazard classes are separated into divisions.
These divisions identify the different types of hazard within a hazard class. For example,
HC 1 (explosives) can have hazards such as fragmentation or fire in the addition to
exploding
✔✔Learn more HC Division - ✔✔HC 1
1.1 Mass explosion hazard (bombs, 155 projectile)
1.2 Fragmentation hazard (some grenades and 105mm cartridges)
1.3 Fire hazard (propellant, artillery charges)
1.4 Minor explosion hazard (small arms ammunition, smoke grenades)
1.5 Very intensive explosives (blasting agents)
1.6 Extremely intensive explosives (no mass explosive hazard)
HC2
2.1 Flammable gases (acetylene, butane, hydrogen)
2.2 Non-flammable, non-poisonous compressed gases (helium, nitrogen, and neon)
2.3 Gases poisonous by inhalation (chlorine, ammonia anhydrous, carbon monoxide)
HC 3
Materials that ignite easily. This is due to flash point. A flash point is the temperature at
which a material gives off enough vapor to ignite. (fuel aviation turbine engine (JP-8),
gasoline, and some alcohol beverages)
HC 4
4.1 Flammable solids that catch fire easily (safety or strike anywhere matches)
4.2 Spontaneously combustible materials that can catch fire without a separate heat
source (charcoal briquettes, linseed oil)
4.3 Dangerous when wet materials (materials that can explode or emit flammable gas
when in contact with water)
i.e. potassium, sodium, MRE heaters
HC 5
, 5.1 Oxidizer: materials that does not burn on its own, but gives off oxygen, which could
cause other materials to burn
i.e. ammonium nitrate fertilizer, hydrogen peroxide
5.2 Organic peroxide (liquid or solid) that contain oxygen
i.e. polyester resin kits used to patch vehicle tires or repair boats
HC 6
6.1 Poisonous materials (liquid or solid) so toxic to humans that it is a hazard to health
i.e. potassium cyanide, arsenic
6.2 Infectious substances: an organism that causes virus or infection in humans or
animals
i.e. medical waste, virus cultures
HC 7
A radioactive material is any material containing unstable isotopes
I.e. uranium, plutonium, thorium
Note: any time you receive or ship rad
✔✔What type of information is found on a Material Safety Data Sheet (MSDS)/Safety
Data Sheet (SDS)? - ✔✔First source of information used to create shipping papers,
mark and label packages, and placard vehicles. It provides crucial information for
Hazard Class 2 thru 9 materials.
Describes who made the material, the ingredients that make up the material, and
possible hazards of the material (birth certificate)
✔✔Why is correct Hazmat information important? - ✔✔Correct Hazmat information
provides safe and handling procedures, which can prevent accidents
✔✔MSDS/SDS and Hazmat Communication - ✔✔Guides you to the information in the
49 CFR. The 49 CFR gives the information to correctly prepare Hazmat communication
(i.e. shipping papers, package markings and labels, and placards)
✔✔MSDS/SDS Uses - ✔✔Describes Class 2 thru Class 9 hazard materials. It is not
used to describe Class 1 explosives
✔✔MSDS/SDS and Hazmat Employees - ✔✔*As a Hazmat employee you use a
MSDS/SDS as a guide for proper and safe handling of a hazardous material
*Emergency personnel
*Every installation must have an MSDS/SDS for every hazardous material, other than
Class 1, that is shipped or stored on the installation.
✔✔MSDS/SDS Section - ✔✔MSDS/SDS Safety Information
Contractor Summary (identifies who to contact if you have questions about the material
or the MSDS)
Item Description Information: provides the material's common name (The item name is
one of the markings on the exterior of a package. It identifies the package contents.)
