Fire Hose Testing
- Acceptance testing and service testing are the two types of hose tests.
- Acceptance testing occurs before delivery; service testing is conducted annually.
LCES Acronym
- LCES stands for Lookouts, Communications, Escape routes, and Safety zones.
- Establishing these is crucial for safety in wildland fire situations.
Fire Classification and Hazards
- Class 3 placards depict flammable and combustible liquids.
- Hazardous materials have nine classifications with specific identifiers for each hazard type.
Risk Assessment in Firefighting
- Conduct a risk/benefit analysis before interior attacks on structures under construction.
- A mechanical advantage pulley system is utilized for rescues to decrease necessary force for lifting.
Firefighting Equipment and Standards
- Underwriters Laboratory (UL) and Factory Mutual Research Corporation (FM) test fire safety systems for reliability.
- Hydrostatic tests are performed on underground piping at a minimum of 200 psi for two hours.
Fire Dynamics and Tetrahedron
- The fire tetrahedron includes fuel, heat, oxidizing agent (missing link is radiation), and chemical reaction.
- Flashpoint refers to the minimum temperature for a liquid to emit ignitable vapors.
Humidity and Water in Firefighting
- Relative humidity (RH) measures moisture in the air as a percentage of saturation.
- Fire flow quantifies available water supply for firefighting operations.
Incident Command and NIMS
