DAMAGE CONTROLINVESTIGATION
“Tricks of the Trade”POWERPOINT
TRAINING
MARCH 2013
After damage investigating requires a sharp eye and understanding of multiple types of obvious and hidden damage and ability to report what
is visualized. Hidden damage, unchecked, can be a ship’s demise.
1. Always look through the window prior to opening door, if available.
3. Open door, enter cautiously
2. Check door for heat, slowly undog door and listen
MULTIPLE REPORTS SINGLE SPACE
Bulkhead deformation, buckled in 3 feet
Ruptured pipe
Deck buckled up 2 feet
Compartment demolished
Light smoke in overheadLight smoke in overhead
1. Make report to DCRS that light smoke in Pway overhead, coming from adjacent compartment (port side)
2. Determine origin of smoke3. Check door for heat, use back of
hand4. SCBA in standby or go on air5. Slowly undog door ¾ ways, giggle
door to check for pressure and listen for air (pressure or vacuum)
6. Observe to see if smoke is heavy or light
7. If flames present at door secure and report
8. Completely undog door, slowly open, observe smoke color and concentration level, look for fire origination

Obvious damage:Obvious damage:Warped Bulkhead
Hidden damage:Hidden damage:
Electrical wires cut or damaged
Cracks in bulkhead, seams, or welds
Air escaping (blowing) through cracks
Warped door frame preventing door from seating properly
Solid sound when bulkhead tapped or sweating on bulkhead (flooding on opposite side)
Damage above, below, forward, or aft of this compartment
Assess the damage by telltale signs
