Study Notes
Objectives of Hazmat Response
- Isolate the area without physical entry.
- Ensure public safety by keeping individuals away.
- Maintain safe distances for people, ensuring they are upwind and away from low-lying areas.
Standard of Care
- Responders must act within their training limits and available equipment.
- Public safety employees have a duty to act but must exercise caution and avoid unnecessary risks.
- Only trained personnel equipped for hazmat situations should approach potential hazards.
Identifying Hazardous Materials
- Accurate identification of hazardous material is crucial while minimizing personal risk.
- Avoid contact with hazardous substances, vapors, or smoke.
- Use shipping documents, interview involved personnel, or rely on bystanders for material identification.
- Make decisions based on awareness-level training if material identification is unclear.
Classes of Hazardous Materials
- USDOT classifies nine common hazardous materials:
- Class 1: Explosives
- Class 2: Gases
- Class 3: Flammable liquids
- Class 4: Flammable solids
- Class 5: Oxidizers and organic peroxides
- Class 6: Toxic substances
- Class 7: Radioactive substances—including nuclear waste and X-ray equipment
- Class 8: Corrosive substances—like acids and solvents
- Class 9: Miscellaneous dangerous goods—not fitting into classes 1-8 (e.g., lithium batteries, asbestos).
Occupancy and Location
- Occupancy types influence potential hazardous materials present (e.g., manufacturing, retail).
- Assess location types (e.g., industrial parks, residential areas) for risks to inform response.
- Assume hazardous materials may exist in unknown environments.
Detecting Hazards
- Observe container shape and size for hazard indicators.
- Look for signs such as pressure release, vapor clouds, chemical reactions, and casualties from a safe distance.
Risk Assessment
- Smell, touch, and taste are high-risk senses not to be used during hazardous material identification.
- Rely on visual and indirect assessment methods instead.
Emergency Response Guidebook (ERG) Usage
- Utilize the orange pages of the ERG for hazardous material identification.
- Focus on three key areas:
- Potential Hazards: Fire/explosion and health impact descriptions.
- Public Safety: Notification procedures, protective clothing requirements, and evacuation protocols.
- Emergency Response: Instructions pertaining to fire suppression, spill control, and first aid.
Public Safety Procedures
- Initial actions include activating emergency response plans and notifying other responders.
- Evacuate areas at risk, adhering to protective action distances based on material type and incident conditions.
Emergency Response Guidelines
- Awareness-level responders must avoid extinguishing fires involving hazardous materials.
- Operational personnel can employ defensive strategies if trained, while technician-level personnel can engage in offensive actions.
First Aid Protocols
- Awareness-level responders should guide contaminated victims to isolated areas without direct contact.
- Victims should await assistance from qualified personnel for decontamination.
Incident Termination Procedures
- Adhere to agency policies for terminating involvement in a hazmat incident.
- Follow OSHA's structured termination process which includes:
- On-scene debriefing about exposure risks and symptoms.
- Incident critique to evaluate strengths and weaknesses.
- After-action analysis for further improvements.
Incident Command System (ICS) Overview
- Officers utilize ICS for managing various critical incidents like vehicle crashes, hurricanes, and wildfires.
- Basic ICS structure may vary by organization but shares common elements.
- Initial response involves obtaining information from dispatch and identifying the type of incident or threat.
Initial Response Actions
- Assess the need for personal protective equipment (PPE).
- Establish the ICS and set up a command post.
- Determine resource requirements, including assistance from other agencies.
- Make decisions regarding shelter-in-place or evacuation, including routes and collection points.
Hazardous Materials Response
- Main objectives in a hazmat incident include isolation of the area, crowd control, and ensuring safety conditions (upwind positioning and avoiding low-lying areas).
- Responder's duty of care must align with their training and equipment capabilities.
- Approach hazardous material situations only with appropriate training and gear.
Identifying Hazardous Materials
- Identification is crucial and must be done without risking personal safety.
- Use documentation, shipping papers, or personnel to identify materials, avoiding contamination risks from fumes or direct contact.
- If the material cannot be identified, operate at an awareness level to mitigate potential hazards.
Classes of Hazardous Materials
- The USDOT recognizes nine classes of hazardous materials and recommends identifying hazards from a safe distance.
- Look for visual indicators like smoke, liquid leaks, chemical reactions, and signs of mass casualties.
Risk Considerations in Sensory Identification
- Smell, touch, and taste are considered high-risk senses and should never be used for identifying hazardous materials.
Emergency Response Guidebook (ERG) Usage
- The ERG is a vital resource for identifying hazardous materials during responses.
- Focus on the orange pages which provide critical information on potential hazards, public safety measures, and protective clothing requirements.
- Notification protocols include activating emergency response plans and communicating with other responders.
Bomb Threat Response
- When approaching a possible bomb threat, assess the credibility by interviewing the threat recipient and other witnesses.
- Be observant of unusual vehicles, abandoned items, and suspicious packages.
- Never definitively declare a location safe without thorough investigation to avoid liability.
Recognizing Suspicious Items
- Bombs may be disguised as ordinary objects; always verify ownership before interacting with suspicious items.
- If a suspicious item is found, prioritize evacuation and promptly report to authorities.
- Collect details about the suspicious item, including its features, and communicate findings to relevant personnel.
Overall Incident Management
- Regular updates from responding personnel are crucial for effective decision-making during incidents.
- Documentation and debriefing are essential components of response protocols to ensure lessons learned are recorded for future training and improvement.
