Q

Principle Methods of fire extinguishing

A

Starvation - Removing fuel from the fire, closing valves, burning out
Smothering - Blocking O2 from the fire, CO2, blankets, foam steam
Cooling - Using water to reduce heat, effective Boundary Cooling
Interference - Preventing the chemical reaction from taking place. Dry Powder does this

Q

Colour and uses of each extinguisher

A

Q

How would you know if your new LSA or FFE equipment is fit for use

A

It would have a Type approved certificate

18
Q

Where could you find specific details on Fire equipment

EG How much Air should be in the SCBA bottle

A

In the Fire Safety Systems Code Book (IMO)

1200L or capable of functioning for at least 30mins
6 litre tank - 200 Bar
4 Litre tank - 300 Bar

https://maritimeexpert.files.wordpress.com/2016/08/imo-fss-code-international-code-for-fire-safety-systems.pdf

19
Q

How Many SCBA are required on a vessel more than 500GT?

A

2 Self Cntained Breathing Apparatus
As stated in REG Yacht Code

20
Q

Advantages of Positive pressure breathing apparatus

A

Pressure inside the facemask is always above atmospheric pressure, even when the wearer is breathing in. The demand valve is set so that the pressure is always slightly above the pressure outside. When the wearer breathes in the demand valve allows further air to enter.
Even if there is damage to the mask, flow rate will increase to push air out, preventing smoke or gas from entering

21
Q

Starting procedure for a BA set

A

Open bottle, pressurize system, then close bottle again
Watch for drop in pressure, should not be more than 10bar per minute
Don equipment, check it is all secure and fits well
Open bottle again, plug in mask, and check for positive pressure, 2 fingers
Close bottle, breath slowly, check whistle is audible at 50 bar
Check there is no skin showing, proceed to door, give air reading to BA controller

Leak test, Positive pressure, Whistle test, skin

22
Q

When does the SCBA whistle Sound

23
Q

Monthly checks for a SCBA set

A

Check harness for damage
Extend all straps fully for easy donning
Check cylinder is secure and full
Pressurize set for 1 minute and see if pressure drops, leaks, hissing
Check mask for damage, extend straps fully
Check on demand valve works, can inhale/exhale
Close bottle and check whistle activates
Check tally/name tag is clean and ready for use

24
Q

EEBDs

A
  • Used to escape from control stations, machinery spaces, accommodation spaces and service area in the event of an emergency.
  • All ships must carry at least two EEBD in the accommodation – and one spare.
  • Passenger ships carrying more than 36 passengers should carry at least four EEBDs in every main vertical zone – and two spare.
  • In machinery spaces, EEBDs should be clearly visible.
  • Use EEBDs to escape from a compartment.
  • EEBDs have a service duration of at least 10 minutes.
  • A full set of EEBD includes a hood or full-face piece (gives protection to the eyes nose and mouth during escape).
25
Fire Control Plans
Can be a combined FFE and LSA plan A general Arraingment plan, that shows the positions of stowage of the life-saving and fire appliances. Should be displayed in the crew area, and a duplicate available at the passarrel in a weathertight case, along with a muster list, for non-crew personel in an emergency
26
What is in MGN 71
Musters, drills, on-board training and instructions, and Decision Support Systems Includes weekly, monthly, quarterly and annual tests required of LSA and FFE

How often should drills be conducted
According to SOLAS and LYC annex C Every crew member shall participate in 1 Fire and 1 abandon Drill each month These must be held within 24 hrs of leaving port if 25% of the crew did not do one last month These should be held before sailing on build, change of major character, or new crew engaged.
33
How to refill a powder extinguisher
Lift up the handle and push the pin back in unscrew the top, replace the spent CO2 cartridge Pour the powder into the extinguisher Replace the top
34
Drills should be/include?
Carried out in the same manner as a real emergency Should involve all Crew and passengers if possible Fire or other drill should be carried out at the same time as the 1st stage of an abandon drill Train crew in the closing/ operation of all openings, hatches, scuttles, dampers etc 1 extinguisher should be discharged at each drill so that crew become familiar with them encourage fire prevention
35
How to respond to a fire in the engine room (OOW on the Bridge)
Find Check the Fire panel for location Check the CCTV/ comms to the ECR for confirmation Send lookout to investigate, tackle if possible Inform Inform the crew - Activate alarm, to muster crew Inform the Master Inform the World- Mayday call Restrict Assess the situation, fix position, slow the vessel or turn downwind if possible Shutdown ventilation close fire doors, watertight doors Extinguish Activate fire pump Handover to Captain when possible report to MUSTER, full headcount to check for missing persons is crucial On command of Captain, close fuel shut-off valves BA team dressing Hoses running Boundary cooling of all 6 sides of compartment if possible Activate fixed fire fighting system, on command of master or C/E Prioritise rescue of persons Medical team to prepare to treat casualties
36
Advantages of AFFF
Aqueous Film Forming Foam Foam blanket prevents fire Foam blocks vapours drom excaping and finding an ignition source Smothers, blocking the oxygen Cools the fuel due to high water content
37
What is the IMDG code?
International Maritime Dangerous Goods Code (Diamond symbols denoting types of dangerous goods, eg Goods which may spontaneously combust) Set by IMO Identifies which goods are dangerous to transport Identifies the hazards they present Ensures correct measures are in place to safely transport them
38
Where can we get more info on Lithium Ion Batteries? Details about them and their risks
MGN 550 - Guidance for safe design, storage and operation of Li Ion Batteries Different in their construction to traditional lead acid batteries Higher energy density, but Greater potential risks Relatively minor damage, or temps of 120ºC can lead to thermal runaway Runaway can quickly produce temps of 1000ºC Also give off toxic and flammable gas
39
Which extinguisher for fats
wet chemical, Yellow
40
What percentage of oxygen in the air is cause for concern
