Study Notes

Hazardous Materials Classes

Class 7 includes radioactive substances such as nuclear waste and medical materials.
Class 8 encompasses corrosive substances like acids and solvents that can cause irreversible human tissue damage.
Class 9 refers to miscellaneous dangerous goods not classified under Classes 1-8, regulated by USDOT. Examples include lithium ion batteries, dry ice, magnetized metals, auto-inflating devices, asbestos, molten sulfur, and PCBs.

Occupancy and Location

Occupancy indicates the type of structure (e.g., manufacturing, storage, retail, residential) and its associated hazards.
Location refers to an area’s use (e.g., industrial parks, business districts) and influences hazard response based on factors like traffic and inhabitants.
Always assume hazardous materials could be present if the building type is unknown.

Container Shape and Size

The shape of a container can provide insight into the potential hazards associated with a hazmat incident.
Technicians are required for offensive fire attacks during hazmat events, emphasizing proper training and protection.

Spill or Leak Management

Personnel responsible for controlling spills must possess proper training and protection to avoid exposure.
Operational-level responders can manage spills from a safe distance, while technician-level responders can handle leak control directly.

First Aid Procedures

Awareness-level responders should stay clear of direct contact with contaminated individuals to prevent secondary exposure.
Contaminated, conscious victims should be encouraged to relocate to isolation and await qualified medical assistance.

Incident Termination Procedures

Follow OSHA regulations with a structured process for terminating involvement in a hazmat incident.
Three key steps: on-scene debriefing to inform responders about exposure risks, incident critique for operational assessment, and after-action analysis for future improvements.

Bomb Threat Search Considerations

Permission must be obtained from the property owner to search an area following a bomb threat.
Assess the level of risk; booby-trapped devices may pose hazards, necessitating postponement or limitation of searches.
A safe perimeter should be established, ideally 1,000 feet from the threat.

Conducting the Search

Utilize knowledge of building layout and threat specifics to create an effective search plan.
Watch for suspicious items, such as abandoned bags or vehicles, and avoid making definitive safety statements to avoid liability.

Recognizing Suspicious Items

Explosives often resemble commonplace objects; maintain caution when encountering or observing any unusual items.
Upon finding a suspicious object, vacate the area immediately and relay identifying features to authorities for further investigation.

Incident Command System (ICS) Training

NIMS offers ICS training through FEMA's website.
Courses include IS-100.C (Introduction to ICS) and IS-700.B (Introduction to NIMS).
Completion of courses and passing online exams is required for certification.

Officer's Role During Natural Disasters

Officers assist with evacuations, traffic control, and providing directions during disasters.
Providing security for emergency shelters is a critical duty.
Knowledge of community demographics enhances response effectiveness.

Community Engagement

Strong relationships with community members improve information dissemination regarding evacuations and safety protocols.
Officers should identify specific community needs (e.g., elderly, non-English speakers) to assist effectively.
Building trust fosters cooperation among community members during crises, potentially saving lives.

Emergency Preparedness

Officers must establish personal emergency plans for their families, including meeting locations and out-of-town contacts.
Prepare disaster kits for 72 hours, containing essential supplies and emergency management contacts.
Awareness of hazardous materials and emergency response plans is crucial.

Hazardous Material Identification

NFPA 704 system provides color-coded diamond markings to identify hazard classifications:
- Blue for health hazards
- Red for flammability
- Yellow for reactivity
- White for special hazards.
Use sight and sound cautiously when identifying hazardous materials to minimize risk.

Military Explosives Awareness

Recognize military ordnance (e.g., grenades, landmines) and treat all discovered devices as live.
Request bomb squad assistance for the proper handling and removal of military explosives.

Improvised Explosive Devices (IEDs)

IEDs are homemade bombs made from common materials; can be disguised and concealed.
Always treat suspicious items as potential explosives; maintain caution in all discoveries.

Mail Bomb Detection

Indicators of mail bombs include:
- Rigid envelopes
- Excessive postage
- Misspelled words
- Handwritten addresses
- Protruding wires or strange odors.
Isolate and evacuate if a suspicious mailing is identified; do not handle it.

Secondary Explosive Devices

Secondary devices are intended to harm responders during emergencies.
These devices can be hidden in everyday objects to cause mass casualties after an initial explosion.

Search Conduct in Emergencies

Conduct systematic searches using building layout knowledge to avoid confusion and ensure thorough coverage.
Develop a search plan if not previously established; chaotic searching may overlook critical areas and overlook potential threats.
