FIRE Flashcards
Four steps to FIRE
Find
Inform
Restrict
Extinguish/Escape
Classes of fire
A. Carbonaceous, flammable solids (wood etc)
B. Flammable liquids (petrol, oil, paint)
C. Flammable gases, (natural gas, hydrogen, propane)
D. Combustible metals (sodium, Magnesium, Pottassium)
F. Cooking fats and oils
ELECTRICAL fires do not have a class, as electricity is the source of the fire. Isolate the electrical current and use an extinguisher developed for electrical use (CO2)
Additionally, LITHIUM fires, use Lithium extinghuisher
Extinguishers and their use (classes) / Advantages/Disadvantages
Water: A
Water: A
Advantages: Cools
Disadvantages: conducts electricity
Extinguishers and their use (classes) / Advantages/Disadvantages:
Foam: AB
A, Solids
B, Liquids
Advantages: Smothers the fire, and cools
Disadvantages: Conducts electricity, Messy
Extinguishers and their use (classes) / Advantages/Disadvantages
Powder: ABC + electrical
A Solids
B Liquids
C Gases
+ electrical
Advantages: Multiple Uses
Smothers Fire
Disadvantages: Can re-ignite later from latent heat.
Powder will damage electrical
instillations
Extinguishers and their use (classes) / Advantages/Disadvantages
AFFF foam
Aqueous Film Foaming Foam
A and B
Advantages: 5 times more effective than regular foam
Disadvantages: Breaks down easily
Extinguishers and their use (classes) / Advantages/Disadvantages
CO2: B, and Electrical
B Liquids
Electrical
Advantages: Quickly starves the atmosphere of oxygen
Disadvantages: Harmful to Human Life in small
compartments/ Large quantities (FFE
in ER)
Extinguishers and their use (classes) / Advantages/Disadvantages
Wet Chemical: A and F
A solids
F Fats and cooking oils
Advantages: Cools Chemicals with high flash points
(galley fires)
Disadvantages: Not suitable for electrical fires
Can cause corrosion to some metals
Extinguishers and their use (classes) / Advantages/Disadvantages
ARGON: D (combustable metals)
Used for Combustible metals such as LITHIUM
Advantages: used against and combustible metals
Disadvantages: Not used for other fire classes
Areas that can be causes of fire:
Self igniting rags/liquids in bins
Laundry lint
Galley operations
Crew hair straighteners etc
Electrical fire (overloading sockets, water on electrical instillations, Faulty wiring)
Machinery failure, Rags left on machinery
Bunkering procedures
Owners/Clients smoking
Aircraft fuel and accidents
What document gives information on:

For how long after hot works must we maintain a watch?
24 hours
Which chapter of SOLAS speaks to Fire?
Chapter II
How long should a BA Cylinder last?
1,200L / 30 Minutes of air
Monthly Checks of Firemans outfit
- Verify everything is in the correct locker
- Ensure Locker is clean, dry and accessible
- Ensure storage bags are undamaged and dry
- Visual check of firemans suit, ready to go fitted over boots, with smoke hood and gloves/socks
- Visual inspection of torch, belt, insulated ax, radios, helmets
Monthly Checks of BA kit:
- Ensure locker is clean and dry, and accessible
- All equipment is in the correct locker
- Cylinder is secure and at at least 90% of the appropriate Pressure
- Straps open, All Equipment undamaged
- Check system for leaks by turning off air and waiting 1m
- Check Positive Pressure
- Test on demand valve Bypass
- Check Mask Spider is open
- Finally, Check the function of the Warning whistle (50Bar)
- Check Tally is clean and in place
Procedure for donning BA kit
- Remove from locker
- Turn on and check pressure
- Switch off, check for any air leaks
- Put on outfit whilst waiting for leaks
- BA kit over outfit
- Pressure back on, ensure demand valve shut
- Check for Positive Pressure/Air leaks from mask
- Test Whistle
- Put smoke hood over head/Mask
- Helmet over smoke hood
- Pressure back on, tag given to OSC, Ready to Go
Where may we find the Fire/Safety Plan?
Bridge
ER
Crew corridor/Crew Mess
Additional FSP, Muster list on the Gangway in W/P tubing, to assist non-fire fighting personnel who may board during a fir
What is a BA system?
Any system designed to provide the wearer with fresh breathable air in an otherwise hostile environment
What is an EEBD?
How much time should it give the wearer?
How many must all ships carry?
Where are they found?
Emergency Escape Breathing Device
10 Minutes
2
ER, Accomodation
Which MGN speaks to Muster, Drills, On board training and instruction, and Decision Support Systems?
MGN 71
How often do we partake in Drills?
- a) Fire- Monthly, 25% crew change
- b) Abandon Ship- Monthly 25% crew change
Both of these if a senior officer Member has changed out
- Enclosed space rescue - 2 months
- MOB, medical emergency, emergency steering - 3 months
- Security, 3 month OR change of master/25% crew change
- Bunker spill drill, before bunkering and 3 months
ANNUAL, catastrophic event
If possible, we should boundary cool from how many directions?
6 Directions/Walls
After setting off CO2 in a compartment to extinguish a fire, how long should we wait before opening any vents/doors?
24 hours
Fire in the ER, Procedure
Find: CCTV, Call the ER, send two crew members with UHF radios
Inform: Call the Master, Sound the Fire Alarm, Make MAYDAY DSC alert/Call, Sat C if in A3, Consider raising Juliet Flag
Restrict: Muster all crew and PASSENGERS, close fuel shut offs, Close W/T and Fire doors, Close fire dampers/Ventilation to ER, Consider altering course after a position assessment, Consider shutting down Machinery
Extinguish: Start fire pumps, Begin actions under emergency plan in ships SMS, RESCUE CASUALTIES, Remain in Bridge until relieved of the watch by the master, or assist Master in resolution as per Muster List
Sprinkler/Drenching systems: advantages/Disadvantages
Advantages: Can quickly cool fires
Disadvantages:
Require a lot of water, Can cause water damage
Has negative effects on Stability
Hi Fog/ Ultra Fog
advantages/Disadvantages
Advantages:
Small droplets and fine mist smother and
cool
Safe for People and the environment
