STCW Basic Training Questions And Answers Graded A+

Ship Fire Prevention - Ship design and construction -steel/fire retardant materials -subdivisions -fire protection systems Good housekeeping practices important Number 1 cause of fire - CARELESS SMOKING HABITS!!! - DISPOSAL - SMOKING IN BED - DISREGARD FOR RESTRICTED AREAS • POOR HOUSEKEEPING - Dirty/oily machinery - Clothes drier lint accumulation - Improper, non-secured storage Examples of poor housekeeping practices - -Complacency about fire safety on the job -careless disposal of smoking materials -defective electrical components -spillage of flammable materials -careless work habits Fire Triangle - fuel, oxygen, heat All of these components are necessary for a fire to occur The removal of any one component will cause the fire to be extinguishedFire Tetrahedron - Heat, Fuel, Oxygen, Chemical Chain Reaction All of these components are necessary for a fire to occur The removal of any one component will cause the fire to be extinguished Heat - Anything that produces the required temperature for ignition will satisfy this leg of the triangle - Sun - Open Flame - Chemical Reaction - Sparks - Friction - Static Electricity - Biological Processes Oxygen - The Earth's atmosphere consists of 21% oxygen Because fire needs oxygen to burn, the amount of oxygen available to it controls the rate at which it burns Fuel - Only vapors burn • Liquids & solids are too dense and must first be vaporized • The tendency of a substance to vaporize is an indication of its ability to burn. • Liquids vaporize more readily than solids • Gases are already in a vapor state Chain Reaction - You can have Oxygen - Heat - Fuel in the same place at the same time and still not have a fire (explain) • FUEL - OXYGEN relationship must be balanced, i.e., must be in the Flammable Range • Heat must be sufficient to bring fuel to its "Ignition Temperature"To Stop a Fire - • remove the fuel • remove the heat • remove the oxygen • interrupt chemical reaction OR • do any combination of above
