examples:
1. Smoking
2. Hot work
3. Galley Activities
4. Machinery spaces
5. Electrical Faults
other:
Fuel oil systems and bunkering
Chemical Reactions
Repair or Refit Ops
Fire Prevention
list 5
- Laundries and drying rooms. Daily checks.
- Wastepaper baskets emptied.
- Galley exhaust ducts cleaned regularly.
- Designated Paint and Fuel Store
- Do not overload power points.
Other:
* Combustible material away from heat sources.
* Steel bins with lids for collecting oily waste.
BA Equipment
What is it?
What type do you have on board?
Any system designed to supply the user with a safe supply of fresh, breathable air in an otherwise hostile atmosphere.
On board: compressed air equipment
Positive Pressure Breathing Apparatus is designed so..
…pressure inside
face mask is always above atmospheric pressure, even when the wearer is breathing in.
Advantages of a positive pressure system
If there is damage to the face mask the system will automatically increase the flow of air so as to keep smoke and toxic vapours out of the mask.
How does the demand valve work on BA?
“first breath” positive pressure sets
Set is in ‘standby’ condition before donning with the cylinder valve open,
When wearer takes his first breath the demand valve starts to work and creates a positive pressure.
Starting procedure BA
(5)
- Apparatus leak test
* Switch off demand valve.
* Open the cylinder valve, close it and observe the gauge. It should not fall. - Don the apparatus
* Check all straps are in good condition, adjust so the back plate fits
snugly.
* With demand valve off, turn on the cylinder slowly. - Check positive pressure + whistle
* Put mask on.
* Spread head harness and place over head.
* Place chin in mask chin cup, tighten lower straps first then upper straps (holding breath).
* First breath will switch DV to positive pressure mode, breathe normally.
* Lift mask seal off face with 2 fingers, air pressure should flow out of mask.
* Allow mask to re-seal. Hold breath and check there is no leakage.
* Close cylinder valve and gently release air from demand valve.
* Observe gauge, whistle will alarm at between 60 bar to 50 bar. - Check the actual pressure gauge
* Turn on cylinder and check reading on pressure gauge. - Proceed to fire location
* Adjust your flash hood over the edges of the mask so that there is no skin showing and all the straps are tucked into place.
* Fit your helmet and put on your gloves.
* Check in at entry control, confirm name and pressure and time of entry noted on BA control board.
* Carry out the team’s brief.
Fire Plans
and its contents
Can be combined with?
A fire control (general arrangement) plan should be permanently displayed for the guidance of the Master and Crew.
The content of the plan should
show and describe:
Principal fire prevention and protection equipment
and materials.
Symbols should comply with a recognised international standard.
The fire control plan may be a combined Fire & Safety Plan:
show positions of life-saving and fire appliances.
What would you see on the passarelle?
Duplicate fire plan
permanently stored in a prominently marked weathertight enclosure
readily accessible
to assist non-vessel fire- fighting personnel.
Drills.
Which drills must be done every month?
How should they be conducted?
SOLAS REG 19 > MGN 71
Every crew member shall participate EVERY MONTH in at least:
- one abandoned ship
- one fire drill
Familiarity with safety installations and practice musters.
Every crew member with assigned emergency duties shall be familiar with these duties before the voyage.
Drills shall try be conducted as if an actual emergency.
According to which regulation?
What vessels do the Drill requirements apply to?
SOLAS REG 19 > MGN 71
‘APPLIES TO ALL SHIPS!!’
The drills of the crew shall take place within 24 hours of the ship leaving port if:
(3)
- more than 25% of the crew have not participated in abandon ship and fire drills on board that particular ship in the previous month
- Ship enters service for the first time, after modification
- Major character or when an entire new crew is engaged.

Boundary Cooling
Ships constructed with steel,
(highly heat conductive construction material)
heat likely to travel through construction and ignite other parts
of ship.
Boundary cooling requires vast amounts of water applied to the decks and bulkheads surrounding the initial fire compartment.
A compartment may have up to
six boundaries to cool.
