37
Q

EOFB
Gas Cooling?

A

Pulses of water into the hot fire gases to cool them below their auto ignition temp to prevent further spread of fire

Q

EOFB
Gas cooling: Short pulse

Branch setting is wide spray
Branch cracked then shut immediately
Each pulse directed in different area

39
Q

EOFB
Gas cooling: Long pulse

A

Branch medium spray
Use Longer pulse depending on penetration
Aim pulse directly in over pressure area
Large rm, aim at roof & wall junction

40
Q

EOFB
what is pyrolysis

A

Decomposition of a substance through the application of heat

41
Q

EOFB
What is Flashover

A

The sudden and sustained transition from developing fire to fully developed

42
Q

EOFB
Direct Attack

A

Applying Extinguishing method directly onto the burning fuel, using jet/spray

43
Q

EOFB
Indirect attack

A

Spraying water onto super-heated surfaces and or fire gases in a compartment to create a mass of steam that displaces the O2 and smothers the fire

44
Q

Safe operation around water
Dry Rescue

A

Throw a throw bag from a dry stable position

Q

Safe operation around water
What is the defensive swimming position?
