Chapter 17— Loss Control
17–2
Chapter 17 Lesson Goal
After completing this lesson, the student shall be able to perform loss control operations
17–3
Philosophy of Loss Control
• Minimize damage & provide customer service through effective recovery efforts
• Builds goodwill
(Continued)
17–4
DISCUSSION QUESTION
How does effective loss control contribute to goodwill in the community?
17–5
Salvage & Overhaul
• Most effective means of loss control
• Restoration of the property
• Salvage - methods & operating procedures that reduce fire, water & smoke damage during & after fires
• Overhaul – Searching for & extinguishing hidden fires
17–6
Salvage
Operations that aid in reducing primary & secondary damage during firefighting
• Primary damage is caused by the fire
• Secondary damage is caused by fire suppression activities
(Continued)
17–7
Salvage
• Both primary & secondary damage can be minimized through salvage
• Some damages cannot be avoided
• Starts as soon as adequate personnel are available
• May be done simultaneously with fire attack
17–8
Overhaul
• Consists of operations involved in searching for & extinguishing hidden or remaining fires
• Protecting the scene & preserving evidence are components of overhaul
(Continued)
17–9
Overhaul
If possible, do not start overhaul operations until
• Fire is under control
• Fire cause has been determined
