					                    OBJECTIVES

•     State the CG firefighting
    policy.

•   Identify the elements and
    characteristics of a fire.

•   Be able to properly
    extinguish a fire using a
    vari-nozzle and/or portable
    extinguisher.
               CG Policy

   Does the CG still fight fires?

   Where can you find info on the CG’s
    firefighting policy?

   What is the CG’s firefighting policy?

HEAT
         What is FUEL?

   A substance that will vaporize
    and/or burn.

Examples:
               Gases
               Liquids
               Solids
           What is HEAT?
   To raise the temperature of fuel
    vapor to its ignition temperature.

   Examples:

   Spark
   Engines
   Flames
What is OXYGEN’s role?

   Combines with fuel vapors.

   Breathes life into the fire.

   At least 15% is required for
    combustion.
      What is CHEMICAL
      CHAIN REACTION?


   When fuel, heat and oxygen
    combine to form flaming
    combustion.

                         AFFF

   Puts out fire by forming a barrier of foam on top of
    liquid.

   Used primarily on Bravo fires.

   Indefinite shelf life.

   94%water 6%AFFF.

   Environmental pollutant except when used during
    a fire.
       HOW AFFF WORKS



           OXYGEN




          AFFF
Fuel
                         PKP

   Primarily used for class Bravo fires.

   18lb ext. range 19 feet-10 sec min. discharge.

   27lb ext. range 21 feet-11 sec min. discharge.

   Corrosive to electrical equipment.

   No cooling effect.
CO2
                   CO2

   Primarily used on class Charlie
    fires.

   Effective range: 4 to 6 feet.

   Minimal cooling effect.

   Static discharge.
          Halon



   Used in fixed systems
   Exposure hazards
   Harmful to ozone
        PROCEDURE FOR
        FIGHTING FIRES
   Brief crew, COMMUNICATION.

   Assign crew specific duties.

   Establish comms with distressed vessel.

   Approach upwind, do not tie any lines to
    distressed vessel.

   If no one on board, circle boat to search for
    persons in water.
       PROCEDURES FOR
        FIGHTING FIRES
   Advise all persons aboard to move to a
    flame free, smoke free area, topside.

   Attempt to determine the extent and
    source of fire.

   If fire is beyond the crew members fire
    fighting capabilities, evacuate persons.
     PROCEDURES FOR
      FIGHTING FIRES


   If fire is small and within crew
    members capabilities,transfer
    the victims to the rescue boat.

   Fight fire.
 Dewatering Procedures
1. PRE-ARRIVAL PREPARATIONS

2. O/S EVALUATIONS AND PREPS
