Some basic points from my recent training session that some wanted me to share. Aside from a singular Burn Mass Casualty Incident, fire may be used as a ruse to stack first responders into tradition response only for the malevolent threat to conduct an unsuspecting ambush attack.
All members of your fire or paramedic teams must conduct an assessment on the way to the call to formulate if any anomalies exist
Consider ingress and egress to the site and any vulnerabilities. Identify an emergency evacuation to fit various ambush attacks
Consider advantageous ambush points for an aggressor
All first responders should understand the differences between “cover” and “concealment”. Immediately identify cover at all calls
Consider ambush attacks may take the form of a low signature attack (edged weapon) firearm, explosive, or vehicular attack
