The inner cordon of the incident may coincide with the 5m zone or may be larger.

Answer 123

Control of Major Accident Hazard Regulations 1999

Answer 124

the stage of a fire where TOTAL THERMAL RADIATION form the FIRE PLUME, HOT GASES and HOT COMPARTMENT BOUNDARIES causes all EXPOSED COMBUSTIBLE SURFACES to PYROLYSE (release flammable gases) and IGNITE when there is adequate ventilation. It is the SUDDEN and SUSTAINED transition from a growing fire to a fully developed fire.

Answer 125

Backdraught is where LIMITED VENTILATION can lead to a COMPARTMENT producing fire gases containing significant proportions of PARTIAL COMBUSTION PRODUCTS and UNBURNED PYROLYSATES. If these accumulate, the admission of air into the compartment when opened can lead to a SUDDEN DEFLAGRATION. which moves through the compartment and out of the opening.

Answer 126

Fire Gas Ingnition occurs when gases from a compartment fire have leaked into an adjacent compartment and mixed with air. This mix may then fall within the appropriate flammable limits, which if ignited will create an increase in pressure, either with or without an explosive force. It is not necessary for an opening to be made for this to occur. If an explosive force is experienced this is commonly termed a SMOKE EXPLOSION. An ignition with much less pressure the term FLASH FIRE is appropriate

Answer 127

High heat conditions Flaming combustion overhead Ghosting tongues of flames No water falling back after "gas cooling" A sudden lowering of the smoke layer The sound of breaking glass as windows fail A change in smoke issueing (increased velocity and darkening in colour towards black) The presence of light coloured smoke from pyrolysis

Answer 128

Fire in tightly closed compartments Darkened windows Windows, doors and door handles hot to touch (back of hand) Rattling sound or pulsating smoke smoke being drawn into back into openings Ghosting tongues of flame in the compartment Turbulance in the smoke layer Whistling or roaring sounds Change to fast moving smoke exiting at high velocity as if under pressure

Answer 129

The removal of heated air, smoke and other contaminants from a structure or other location and their replacement with a supply of cooler cleaner air.

Answer 130
