STCW BASIC TRAINING PRACTICE SOLUTION
2026 TESTED QUESTIONS WITH EXPERT
EXPLANATIONS GRADED A+
◉ Number 1 cause of fire. Answer: 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. Answer: -Complacency
about fire safety on the job
-careless disposal of smoking materials
-defective electrical components
-spillage of flammable materials
-careless work habits
◉ Fire Triangle. Answer: 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 extinguished
◉ Fire Tetrahedron. Answer: 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. Answer: 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. Answer: 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. Answer: 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. Answer: 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. Answer: • remove the fuel
• remove the heat
• remove the oxygen
• interrupt chemical reaction
OR • do any combination of above
◉ Classifications of Fires. Answer: Five classes of fire:
1. Class A - combustible solids (wood paper, rubber)
2. Class B - combustible and flammable liquids and gases (oil, gasoline)
