Hazmat Incident Response Objectives

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.
