Dangers to firefighters

• Disorientation in large rooms
• Ventilation dangers to firefighters
• Truss collapse onto firefighters
• Floor collapse under firefighters
• Wall collapse
• Backdraft and flashover

17
How can we be proactive ?

• Identify buildings
• Preplanning
• Code enforcement
• Develop SOPs
• TIC training
• Search/orientation
• RIT training
• Survival training

• Thorough size-up !
• ICS
• Recognize hazards
• Communicate hazards
• Proper strategy
• Proper tactics
• Accountability
• Post-incident analysis

What did we learn ?

• We identified 3 engineered wood components
• We learned what they are used for
• We learned where we can find them
• We learned they how react to fire exposure
• We learned some danger they expose us to
• Ways we can be proactive
