Terrorist Attacks, Criminal Activities, and Disasters

Referencing the content of hazardous materials awareness and operations at the awareness level

Intentional releases and illicit labs demand law enforcement primacy, defensive distances, and NIOSH fentanyl precautions without unnecessary entry.

Learning objectives (6)

Recognize intentional indicators — Multiple victims, dispersal devices, or coordinated symptoms without industrial source.
Apply secondary device precautions — Maintain standoff, avoid clustering equipment, follow bomb-arson protocol coordination.
Follow NIOSH fentanyl guidance — Avoid unnecessary exposure; use PPE per agency policy for suspected opioids.
Preserve crime scene — Minimize evidence disturbance; coordinate with law enforcement.
Defensive size-up for suspicious packages — Isolate, deny entry, request bomb tech and hazmat assets.
Disaster combo awareness — Floods and wind can damage tanks and move containers.
