Exercise VII. Read about Fire Extinguishers and be ready to answer the questions.
A fire extinguisher is designed to attack a fire onboard in the early stage.
Water, Foam and Dry Powder
Extinguishers with water, foam or dry powder operate in the same principal. In each case water, foam or dry powder are stored in a welded container. When the valve is opened, CO2 gas has a downward pressure on the water, foam, or dry powder and forces it us a sphon tube and out through the delivery hose. The discharge is controlled by squeezing and releasing the operating head valve or by a control lever at the end of the discharge hose.
WATER Use on wood paper, plastics
DO NOT USE on fires involving liquid (oils, paints, fats, etc.)
DO NOT USE on fires where there is live electricity.
FOAM Use on liquid spills and liquid fires of oils, paints (Class B fires)
DO NOT USE on fires where there is live electricity.
DRY POWDER
Powder can be used for liquids (Class B fires). Powder may also, with the correct technique, be used to extinguish a high pressure gas flame (Class C fires). Dry Powder gives as fast flame knock down, and may be used on fires on live electrical equipment.
True or False?
1. Extinguishers with water, foam or dry powder operate in the completely different principal.
2. Extinguishers with water can be used on fires involving liquid.
3. Powder can be used for liquids.
4. Extinguishers with foam can be used on fires where there is live electricity.
5. Dry powder extinguisher is user on wood and plastics.

Fire-Fighting
Accidents can be caused by negligence of a crewmember or by external factor. The crewmember can choose wrong personal protective equipment or incorrect usage of life-saving appliances or fire-fighting equipment.
A fire doesnt break out if you perform all the precautions. When a fire breaks out, youll try to restrict to its area. The larger fire is, the more difficult it is extinguished. The cargo holds often contain large amount of combustible substances. It is not always possible to restrict fire there. Special transverse bulkheads of the cargo holds prevent spread of the fire to adjacent compartment.
There is the following fire-fighting equipment on board a ship: ships fire alarm system, fire extinguishers, fire hoses with the nozzles, boxes with sand, buckets, fire shovels, axes and crowbars. For accommodation area there is automatic sprinkler system. The CO2 system is used in the engine room.
All the fire-fighting systems and equipment should be in good operating condition ready for immediate use. The deck department is responsible for all portable fire-fighting equipment, while the engine department takes care of all fixed fire-fighting systems.
ASWER THE QUESTIONS: 1. What are the reasons of the accidents? 2. What
can any crewmember do to prevent the fire breakout? 3. Why is it impossible to restrict the fire in the cargo hold? 4. What fire-fighting equipment do you know? 5. What system is used on galley?
