(Continued)

17–4

DISCUSSION QUESTION

How does effective loss control contribute to goodwill in the community?

17–5

Salvage & Overhaul

• Overhaul – Searching for & extinguishing hidden fires

17–6

Salvage

Operations that aid in reducing primary & secondary damage during firefighting

• 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

(Continued)

17–72

Overhaul Procedures
