FIRE PREVENTION MEASURES

Fire prevention measures of ships are provided by its constructive, organizational and technical aspects and also by adequate actions of the crew in their fight against fire. It is noted that considerable per cent of fire accidents are connected with the explosion and ignition of light type fuel. Explosions of hydraulic systems, short circuits, defects in electrical equipment have also high frequency. Usually fire in the engine room is the result of lubricants ignition in the bearings of the main and auxiliary mechanisms.

The other type of thermal accidents takes place because of the open fire that is because of sparks during welding process. But we mustnt forget about negligence of the crew or ship builders shortcomings. It is necessary to observe requirements on storage of dangerous materials. Hold should be dry and clean with appropriate ventilation. Paints must have low thermal conductivity with the aim to lessen the spreading speed of fire.

Inflammable materials must have inscription and marking, be checked periodically on validity and expiration date, leakage, tightness of cover and so on. It is compulsory for every ship to have highly efficient fire extinguishing system and also individual oxygen apparatus, means for hands protection, in a word everything that is necessary to safe life of every man at sea.

 

ANSWER THE QUESTIONS: 1. What is the main reason of fire on board a ship? 2. What measures can we take to lessen the spreading speed of fire? 3. Why is it necessary to have markings and inscriptions on inflammable goods? 4. What is compulsory to have on board every ship? 5. How do builders shortcomings influence on origin of fire?

Mr. Klimov: How do you do Mr. Brown. I am 3rd officer. My name is Klimov. What can I do for you?

John Brown: Well, I am to inspect your ship. First of all I want to see the hatches where cargo operations are going on. Under the rules of our port you should place fire extinguishers at each hatch and lay fire hoses connected with shore pumps.

Mr. Klimov: Certainly, sir. We dont violate the rules. Weve posted a deck-hand on fire watch. He makes regular rounds around the ship and reports to me every half an hour.

John Brown: Very good. And now Ill see the certificate for the ships fire equipment I see everything is ship-shape. All certificates are valid and I have no claims.

Exercise VI. Read the information provided about types of fire and fill in the table.
Be advised that Multiple classification systems exist, with different designations for the various classes of fire. The United States uses the NFPA (National Fire Protection Assosiation) system. Europe uses the European Standard Classification of fires.

TYPES OF FIRE

(European Standard)

It is important to find out the type of fire because if you fight with a fire in incorrect way, it can only increase the danger.

CLASS A CLASS B CLASS C CLASS D
Fire of solid materials usually of an organic nature such as wood, paper, furniture, plastics, rope, etc. Fire of liquids such as petrol, oils, paraffin, paint, cooking fats, etc.   Fire of gases such a propane, butane, acetylene, etc.   Fire of burning metals such as aluminum, magnesium, etc.  

 

ELECTRICAL FIRE: Electricity does not burn. An electrical fire is a Class A, B, C or D fire. After the electrical circuits are isolated, the fire is extinguished as normal according to its normal class.

What is burning? Fire Type
A B C D
Wood        
Petrol        
Wax        
A Television        
Manganese        
Paint Stripper        
Olive Oil        
Cupboard        

 

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 as a siphon 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 used on wood and plastics.

6. Class C fires are extinguished with Dry powder extinguishers.

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.

 

ANSWER 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?
