Study Notes
Classes of Hazardous Materials
- Class 7: Radioactive substances include nuclear waste and X-ray equipment.
- Class 8: Corrosive substances such as acids and solvents can cause irreversible damage to human tissues.
- Class 9: Miscellaneous dangerous goods not covered in Classes 1–8 include lithium-ion batteries, dry ice, magnetized metals, airbags, asbestos, and hazardous waste.
Occupancy and Location
- Occupancy indicates the use of a structure, such as manufacturing or retail spaces.
- Location encompasses areas like industrial parks and residential neighborhoods, affecting hazard response based on traffic and time of day.
Evacuation
- Evacuate the immediate danger area and downwind regions based on material type and incident specifics.
- Protective action distances vary depending on the hazardous material, spill size, and weather conditions.
- Follow agency policies during evacuation to prevent greater hazards, especially in populated areas or near critical facilities.
Emergency Response
- Fire Response: Non-trained personnel must not engage in firefighting during hazardous material incidents. Only operational-level responders with proper training and equipment should attempt defensive actions.
- Military Ordnance: Recognize devices like grenades and landmines, and assume they are live. Clear areas and contact bomb squads for removal.
Explosive Devices
- Improvised Explosive Devices (IEDs) are homemade bombs made from common materials, often concealed to avoid detection.
- Mail Bombs: Indicators include rigid packages, excessive postage, misspellings, and unusual odors. Isolate and evacuate if suspicious.
- Vehicle-Borne IEDs (VBIEDs): Powerful devices hidden in vehicles; indicators include suspicious parking and strange odors. Establish a large evacuation perimeter if suspected.
Incendiary Devices
- Incendiary Devices like Molotov cocktails can cause significant destruction. They include an ignition source, combustible material, and a container.
Searching for Devices
- Follow systematic search plans for potential explosive devices, starting from the exterior and moving indoors.
- Check high-risk areas first, such as entryways, restrooms, and utility rooms, and remain vigilant for booby traps.
- Use tape to mark searched areas and consider safety when entering spaces.
Evacuation Procedures
- Immediate danger area must be isolated before evacuating surrounding populations.
- Protective action distance varies based on hazardous material type, spill extent, and fire potential.
- Consult emergency response guides to determine safe distances for evacuation.
- Extended incidents with fire or explosion risk warrant immediate evacuation.
- Hazard assessments consider geographic and weather conditions affecting material distribution.
Emergency Response
- Divides into three critical subsections: fire response, spill or leak management, and first aid.
- Awareness-level responders are restricted from extinguishing fires with hazardous materials due to insufficient training.
- Only operational-level personnel with appropriate training and resources can conduct defensive fire attacks.
- After-action analysis focuses on identifying weaknesses and enhancing training for responders.
Methamphetamine Laboratories (Meth Labs)
- Meth labs range from small, covert setups to large-scale operations.
- Manufacturing typically involves pseudoephedrine or ephedrine and numerous common household chemicals.
- Key materials indicating a meth lab include coffee filters, two-liter bottles, lithium batteries, and drain cleaner.
- Chemical odors linked to meth labs may include characteristics resembling rotten eggs.
- Dead vegetation is often found surrounding these sites, indicating chemical contamination.
Chemical Suicide Indicators
- Establish a safe perimeter around potential chemical suicide scenes; do not allow public entry.
- Signs for caution include unresponsive individuals in vehicles, taped warning signs, and the presence of unusual odors.
- Resuscitation efforts are discouraged if specific indicators are present, such as suicide notes or chemical residue.
- Symptoms of chemical exposure range from mild irritation to severe respiratory issues and potentially fatal outcomes.
Explosive Devices Awareness
- Recognize that various types of explosive devices exist; not all can be identified by responders.
- Essential to gather information including threat nature, suspected detonation time, and device descriptions.
- Evacuating at least 30 minutes before an alleged detonation enhances safety.
- Location knowledge aids in planning appropriate responses and communication during threats.
Threat Credibility Assessment
- Collect detailed information regarding the threat, including witness statements and previous incidents.
- Surveillance footage can prove crucial in establishing threat credibility.
- Treat all bomb threats as credible until explicitly proven otherwise; immediate safety measures should be prioritized.
- Mandatory evacuation orders are enacted upon discovery of explosive devices; gather evidence from any physical threat forms.
