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.
