What could happen when hazardous materials that react dangerously
when in contact with each other are transported together? – ANSWERPossible 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 – ANSWER- 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 – ANSWER- 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 radioactive materials, you must work
with your Radiation Safety Officer
HC 8
Materials (liquid or solid) that causes destruction to the human body
upon contact (also includes liquids that corrode metals, like steel or
aluminum)
i.e. sulfuric acid, hydrochloric acid, sodium hydroxide
HC 9
Material that presents a hazard during transportation and does not fail
under any of the other eight hazard classes
I.e. asbestos,, airbag inflators, dry ice when transported by air or vessel,
cotton, when transported by land or vessel
What type of information is found on a Material Safety Data Sheet
(MSDS)/Safety Data Sheet (SDS)? – ANSWER- 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? – ANSWER- Correct
Hazmat information provides safe and handling procedures, which can
prevent accidents
MSDS/SDS and Hazmat Communication – ANSWER- 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 – ANSWER- Describes Class 2 thru Class 9 hazard
materials. It is not used to describe Class 1 explosives
MSDS/SDS and Hazmat Employees – ANSWER- *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 – ANSWER- MSDS/SDS Safety Information
Contractor Summary (identifies who to contact if you have questions
about the material or the MSDS)
