Hazard Materials 3 Flashcards
What is the definition of Hazmat?
Hazardous Materials
Refers to any substance that poses an unreasonable risk to safety, health, and property.
Define Hazardous Materials.
Any substance or material in any form or quantity that poses an unreasonable risk to safety, health, and property
This includes various chemicals and materials that can be harmful.
When approaching a Hazmat incident, where should responders position themselves?
Upwind, uphill, and upstream
This positioning helps to avoid exposure to hazardous materials.
What are the roles of First responders at a Hazmat incident?
- Recognize incident
- Protect yourself and others
- Initial response objectives
- Immediate Action
- Manage Incident until relieved
- Transition command
These roles ensure safety and effective management of the incident.
List the nine classes of the Placard and Label system.
- Class 1: Explosives
- Class 2: Gases
- Class 3: Flammable liquids
- Class 4: Flammable solids
- Class 5: Oxidizers and organic peroxides
- Class 6: Toxic and infectious substances
- Class 7: Radioactive materials
- Class 8: Corrosives
- Class 9: Miscellaneous
Each class represents a different type of hazardous material.
What does the Blue Section of the NFPA 704 System indicate?
Health Hazards
This section provides information on the health risks associated with the material.
What does the Red Section of the NFPA 704 System indicate?
Flammability
Indicates the flammability risk of the material.
What does the Yellow Section of the NFPA 704 System indicate?
Reactivity/Instability
This section denotes the stability of the material and its potential for reaction.
What does the White Section of the NFPA 704 System indicate?
Special Precautions
Provides additional safety information regarding the material.
What is the purpose of the DOT Emergency Response Guidebook?
- Yellow Section: UN ID numbers
- Blue Section: Chemical names
- Orange Section: Precautionary information
- Green Section: Evacuation/isolation distance
This guide assists responders in managing hazardous materials incidents.
What is Guide 111 used for?
The unknown
This guide helps responders when the specific material is not identified.
Why should the Green pages of the DOT Emergency Response Guidebook be used first?
Because it’s the immediate actions of what to do
These pages provide immediate action steps for responders.
What tanker classification is MC/DOT 306/406?
Atmospheric pressures, Typical gasoline or fuel oil transports
These tankers are designed for transporting flammable liquids.
What does MC/DOT 307/407 classify?
Low Pressure flammable, poisons, and light corrosive liquids
This classification includes specific types of hazardous liquids.
What is MC/DOT 312/412?
Atmospheric pressure, high density liquids and corrosives
These tankers are built for more hazardous materials.
What does MC/DOT 331 refer to?
High pressure, liquified gases
This classification includes tankers for transporting compressed gases.
What does MC/DOT 338 classify?
Atmospheric pressure, refrigerated or cryogenic liquids
These tankers are designed for very low temperature liquids.
What is MSDS?
Material Safety Data Sheet
Fixed facility information sheets on specific chemicals.
What does PPE stand for?
Personal Protective Equipment
Equipment worn to minimize exposure to hazards.
What does PASS stand for?
Pull, Aim, Squeeze, Sweep
This is a method for using a fire extinguisher effectively.
List the Fire Classifications and Extinguisher Classifications.
- Class A: Ordinary combustibles (wood, paper, cloth, trash)
- Class B: Flammable liquid (grease, oil, gasoline)
- Class C: Energized electrical (motors, transformers, appliances)
- Class D: Combustible metals (potassium, sodium, magnesium)
- Class K: Cooking oils and grease (animal and vegetable oils)
Different classes of fires require different types of extinguishing agents.
