Study Notes
Hazardous Materials Emergencies
- Correctional facilities utilize hazardous materials including cleaning agents, bleach, fuels, and pesticides.
- A hazmat emergency can occur when a hazardous substance is released or not properly controlled.
- Inmates could accidentally mix common chemicals, posing a risk.
- Hazardous materials can be inhaled, ingested, absorbed, or injected, leading to immediate and long-term health risks.
- Hazardous materials can cause environmental harm by polluting water, air, and land.
Identifying Hazmat Incidents
- Hazardous materials may have distinct smells, but some are odorless.
- Never attempt to identify a hazardous material by smell or taste.
- The weight and texture of a container can be used to identify the contents.
Response to Hazmat Incidents
- The Department of Transportation (DOT) Emergency Response Guidebook (ERG) assists first responders in identifying hazardous materials and implementing initial safety measures.
Classes of Hazardous Materials
- Class 1—Explosives: Exposure to heat, shock, or contamination can result in thermal and mechanical hazards.
- Class 2—Gases: Containers may rupture violently under pressure or due to fire, and the substance can become flammable, poisonous, corrosive, asphyxiating, or oxidizing. May cause frostbite.
- Class 3—Flammable and Combustible Liquids: Containers may rupture violently from heat or fire, and the substance can be corrosive, toxic, and thermally unstable.
- Class 4—Flammable Solids: Some are spontaneously flammable, may be water reactive, toxic, and corrosive, and difficult to extinguish.
- Class 5—Oxidizing Substances: Supports combustion due to its oxygen content, sensitive to heat, shock, friction, and contamination.
- Class 6—Poisons and Infectious Substances: Toxic by inhalation, ingestion, and skin or eye absorption, may be flammable.
- Class 7—Radioactive Substances: May cause burns and biological effects, can contaminate surroundings.
- Class 8—Corrosives: Causes tissue disintegration, may be fuming, water reactive, and destructive to metals.
- Class 9—Other Regulated Materials (ORM): Miscellaneous.
Indicators of Hazardous Materials
- Placards (diamond-shaped signs)
- Markings
- Shipping papers
- SDSs (Safety Data Sheets)
- Storage containers
- Visual: Observe for smoke, fire, vapor, or gas clouds. Green smoke is especially dangerous.
- Hearing: Note unusual sounds like hissing from a leak or bubbling from chemical mixing.
- Smell, Taste, Touch: Do not use these senses intentionally.
Equipment Used in Response
- Personal Protective Equipment (PPE): Face mask, protective gloves and gowns, hazmat suit, SCBA, bloodborne pathogens cleanup kit, barriers.
Standard Procedures for Responding to a Hazmat Emergency
- Each agency establishes policies and procedures for hazmat emergencies.
- As a correctional officer, you should respond within the scope of your training.
- Stay aware and be prepared to relay information.
- Follow officer safety and universal precautions while assisting in cleanup.
- Maintain situational awareness and avoid tunnel vision.
- Consider all hazmat incidents as life-or-death situations.
Resolving a Hazmat Situation
- Locate and verify the nature of the emergency: Observe from a safe distance. For minor spills, follow SDS guidelines.
- Refer to the SDS: Ensure an SDS is readily available for emergency personnel.
- Communicate with control room staff and supervisors: Relay information about substances, affected areas, medical emergencies, and wind direction.
- Enter the area only when safe: Use PPE immediately and disposable equipment whenever possible.
- Provide first aid to the injured and separate contaminated people.
- Evacuate affected areas: Evacuate everyone safely as soon as possible. Use upwind and uphill evacuation routes. Follow posted evacuation diagrams.
- Isolate the situation: Shut off air conditioners, close doors and windows, stay as far away as possible (minimum of 500 feet). Do not introduce ignition sources.
- Create a barrier or perimeter: Use signs, warning tape, physical barriers, and officers stationed outside the secured area.
- Observe special precautions during decontamination efforts: Ensure victims and equipment are decontaminated before contact. Decontaminate yourself and your clothing if contaminated.
- Restrict or control access: Only emergency personnel are authorized to enter the area. Maintain a record of events.
