FIRE SCHEDULE Delta
F-D
FLAMMABLE GASES
| General comments | Gases in closed tanks exposed to heat may explode suddenly in or after a fire situation by a boiling liquid - expanding vapour explosion (BLEVE).
Crew members should be aware of the explosion hazard and take appropriate action. Keep tanks cool with copious quantities of water. Fight fire from a protected position from as far away as possible. Extinguishing a burning gas leak may lead to the formation of an explosive atmosphere. Flames may be invisible. |
||
| Cargo on fire on deck | Packages | Create water spray from as many hoses as possible. Do not try to extinguish a gas flame. |
|
| Cargo Transport Units | Cool burning transport units and nearby cargo exposed to the fire with copious quantities of water. Do not try to extinguish a gas flame. |
||
| Cargo on fire under deck | Stop ventilation and close hatches. Use cargo space fixed fire-extinguishing system. If this is not available, create water spray using copious quantities of water. |
||
| Cargo exposed to fire | If practicable, remove or jettison packages which are likely to be involved in the fire. Otherwise, keep cool for several hours using water. | ||
| Special cases: | |||
| UN 1038, UN 1075, UN 1965, UN 1966, UN 1972, UN 3138, UN 3160, UN 3309, UN 3312 | SUDDEN OR SHORT-TERM EVENTS (E.G. EXPLOSIONS) MAY ENDANGER THE SAFETY OF THE SHIP. | ||
| UN 1001, UN 3374 | Acetylene is a gas which is particularly dangerous due to its potential to explode. Rough handling or local heating may lead to delayed explosion. Keep cool for several hours using water. Do not move receptacles. All cylinders that have been subjected to rough handling or to local heating should be jettisoned. | ||
| UN 3501, UN 3504, UN 3505 | A flammable liquid, paste or powder may be expelled if the package is ruptured. Also consult FIRE SCHEDULE F-E. | ||
