110.1 What are the six categories of hazardous material?
May be a solid, liquid or gas. Basically any material with a low flash point, or point at which it ignites into flames.
b. Toxic materials
A poison or toxin is a substance that adversely affects one's health by causing injury, illness, or death, when inhaled, injested, or through contact.
c. Corrosive materials (including acids and bases)
A highly reactive substance that causes obvious damage to living tissue. It is a chemical that causes visible destruction of, or irreversible alterations in, living tissue by chemical action at the site of contact.
d. Oxidizing materials
Oxidizing materials are liquids or solids that readily give off oxygen or other oxidizing substances, such as chlorine. They also include materials that react chemically to oxidize combustible (burnable) materials; this means that oxygen combines chemically with the other material in a way that increases the chance of a fire or explosion. This reaction may be spontaneous at either room temperature or may occur under slight heating. Oxidizing liquids and solids can be severe fire and explosion hazards.
e. Aerosol containers
Aerosols are tiny liquid and solid particles suspended in the air. Insecticides, oils and paints are examples of aerosols in pressurized containers. Chlorofluorocarbons (CFCs) are good propellants, and present no fire danger, but they are being phased out as they are believed to be a contributory factor to the depletion of the ozone layer in the upper atmosphere.
Hydrocarbons are sometimes used in Aerosol containers, and can present a fire and explosion hazard.
f. Compressed gases
Three major groups of compressed gases are stored in cylinders: liquefied, non-liquefied and dissolved gases. All compressed gases are hazardous because of the high pressures inside the cylinders. Some pure compressed gases are chemically unstable. If exposed to slight temperature or pressure increases, or mechanical shock, they can readily undergo certain types of chemical reactions. These reactions may become violent, resulting in fire or explosion. Compressed flammable gases, such as butane, can burn or explode under certain conditions. Compressed oxidizers can react rapidly and violently with combustible materials. Many compressed gases are toxic or very toxic. They could cause various health problems depending on the specific gas, its concentration, the length of exposure and the route of exposure. Some compressed gases are corrosive, and can burn and destroy body tissues on contact. Even inert gases, such as helium, can cause death or injury in high concentrations
Example: OBA Canister (Oxygen) HMUG Group 18 and;
Petroleum based materials/fuels HMUG Group 8,9, 10
Reaction: Explosion hazard
1. Discovery and notification
MSDS Sheet- Health and Safety data and PPE recommended sections will tell you
HMUG- Has a reference guide in the index that will tell you the noun name and Group
PMS Card- Required PPE will be listed under the Tools/Materials section.
b. Inport: Garbage to pier. Local Guidelines.
c. Inport: Plastic to pier. Local Guidelines.
d. Inport: Sewage CHT collection to pier/ovbd discharge
e. Inport: Oily waste, no sheen. Less than 15 ppm
f. Inport: Paint -Turn into HAZWASTE facility.a. Flammable or combustible materials
.2 Explain incompatible material and describe an example.
Refers to two (2) or more different substances that when mixed could/will cause a reaction
.3 Explain the information and procedures to be followed when a HM/HW spill is discovered.
in some form. The way for identifying incompatible materials is using the MSDS for
the material, Hazardous
Material Users Guide, or the incompatibility chart located in
OPNAVINST 5100.19C Appendix C-23A.
The skeleton structure that must be followed when dealing with hazardous material spill
.4 State the personal protection equipment required when handling HM/HW.
response:
2. Initiation of action
3. Evaluation
4. Containment and damage control
5. Dispersion of gases/vapors
6. Cleanup and decontamination
7. Disposal of contaminated materials
8. Certification of re-entry
9. Follow-up reports
This can be found in one or all of three sources:
