Study Notes
Firefighting Basics
- Approach downed power lines by taping them off for safety.
- Fire extinguishment is targeted based on the material burning.
- Fog stream nozzles produce small water droplets for effective extinguishing.
Tools and Equipment
- Spanner wrench is utilized to couple or uncouple hoses with lugs or pins.
- Straight stream nozzles provide a direct, adjustable water flow.
- Piercing nozzles penetrate materials to deliver water streams internally.
- Water curtain nozzles create protective water screens to shield exposures from flames.
Firefighting Operations
- Low volume nozzles produce a flow rate of 40 gallons per minute.
- When a mayday is called, all communications pause until the situation is resolved.
- SCBA operations require listening for low alarms after two to three turns before completing valve activation.
Fire Dynamics
- Backdraft occurs in an oxygen-deficient environment, indicated by 19.5% oxygen levels.
- PASS alarms sound off for 30 seconds if no movement is detected.
- The decay stage of fire development signifies a decrease in fuel supply.
Firefighter Safety
- Maintain three points of exit when dismounting a truck.
- Class A fires involve ordinary combustibles; Class B involves flammable liquids; Class C pertains to electrical fires.
- When evaluating downed firefighters, assess their conditions critically.
Rope and Rescue Techniques
- Life safety rope is designated specifically for rescue operations.
- The working end of the rope is used for knot formation, while the standing part lies between working and running ends.
- Dynamic ropes are designed to elongate under load, while static ropes have limited elasticity.
Fire Extinguishing Agents and Tactics
- Fire classification symbols: Class A - green triangle, Class B - red square, Class C - blue circle, Class D - yellow star, Class K - black hexagon.
- Stay oriented in dark, smoky environments by holding a hose line or guideline.
Structural Firefighting
- Building types vary by fire resistance: Type I is fire-resistant, Type II is non-combustibles, Type III is ordinary, Type IV is heavy timber, Type V is wood frame.
- When using hoses, the forward/hose lay refers to laying towards the fire, while reverse/hose lay involves laying back to the hydrant.
Communication and Responses
- Trunked radios maximize efficient use of radio frequencies in firefighting.
- The typical evacuation signal consists of three blasts on an apparatus air horn for 15 seconds.
Salvage and Overhaul Operations
- Salvage procedures should run concurrently with fire attacks to protect property.
- When performing overhaul, expose void spaces by opening walls and ceilings while preserving structural integrity.
Additional Firefighting Knowledge
- Water weighs 8.3 pounds per gallon.
- For lifting tools, maintain proper hoisting techniques: axes head-down, pike poles pointing upward.
Hydration and Safety Measures
- Monitor air supply and alarms in SCBA; a low air warning sounds at 35% air cylinder pressure.
- Handle firefighting equipment properly, ensuring items are loaded safely and effectively for rapid deployment.
