Cat Haz Flashcards
What are the 2 types of hazard and what is the higher priority?
- Fuse (higher priority)

When should you conduct a hazard assessment on an EOD task?
- Receipt of task
- Arrival and questioning
- First sighting on long range recon
- Close in Recon
- Evaluation Phase

Shield as detailed in ref manual
What are the mitigations for Jet

What are the mitigations for Long Delay
Hold for all unknown bomb fuses, recon after generic wait
After POS ID wait time as directed
NOTAM and QDR 2 after POS ID (Quantity distance range)
What are the mitigations for Clockwork
DON’T - Knock, strike or jar
Wait 1.5 times max time setting if known
First approach listen for ticking
Remote listening post with regular checks
Unknown fuse ticking, IA evacuate
Known fuse ticking, as per procedure
What are the mitigations for Booby Trap
Hold if ground has been ant enemy access since UXO landed (intel on enemy)
Treat all mines as booby trapped
Look, feel, prod, I.e F3, Ghostwire drills as per threat assessment
Mark clear areas
Remotely move only
What are the mitigations for Ejection
Carriers, mines, ports and other bursters that eject a payload, stay clear of ejection port/opening.
Use cation around undeployed tail assemblies
What are the mitigations for Magnetic
Hazard takes precedence over EMR hazard
Do not change state of radar, RF emitters etc
No vehicles within area
Remove all metal from body
Do not disturb metal in area
Non-magnetic tools
PPE on as soon as magnetic hazard dropped
Protective clothing as first return to ICP
What are the mitigations for Acoustic/Seismic
No vehicles in area
Secure/remove loose clothing that makes a noise
No vocals near approach
Full acoustic silence near device
Any noise freeze for time
No metal/metal contact
If UXO is touched do not rub or slide hands
What are the mitigations for Phosphorous
PPE including respirator on approach
First aid and water available
Do not inhale smoke
S10 must be carried on the man
Emergency services to cordon
Wet sand/water available down range (transport)
Approach from upwind unless other hazards dictate
What are the mitigations for Fire
Do not inhale smoke or fumes
PPE is mask/gloves or S10 carried on the man
Emergency services to cordon
Wet sand available down range (water may induce reaction)
Approach from upwind unless other hazards dictate
What are the mitigations for Fuel
