LNG EXAM 3 QUESTIONS AND ANSWERS|
LATEST UPDATE
what prep is necesary before hot work test atmosphere, remove flammable materials,
ensure no additional release of vapor/liquid, ventilate space, piping gas freed
F.I.R.E. find
inform
restrict
extinguish
3 catagories of lNG fires jet fires- result form small leaks of vapor in pump glands, leaks
are under pressure, jet type flame occurs from the leak location
pool fires- unlikely on ships. pool diameter and wind are two biggest issures, fixed dry powder
arranged around containmnet dams
compressor room fires-protected by fixed, remote activiates FE systems
fire extinguishment water- never use, can cool exposed surfaces
dry powder- sodium bicarbonate and potassium bicarbonate. they attack the flame by
absorbing free radicals in the combusion process, but neglect cook effects
foam-wont extinguish lNG fire
CO2-good for enclosed spaces. 2 disadvantages being that co2 displaces oxygen and the release
of co2 generates static electricity
, principle hazards on LNG ships flammability
vaporization of spilled liquids
toxicity
frostbite
brittle fracture
aims of emergency plan rescuring and treat casualties
safegaurding others
minimizing property/enviro damage
bring incident under control
emergency plans for... cargo transfers
collison
grounding
check fro missing/trapped persons
water leaking into hold
cargo containmnet leakage
four basic elements of emergceny plan organization structure emergency command
center
emergency party
back up emergency party
engineering group
(sometimes a reserve team as well)
