Study Notes
Fire Extinguisher Symbols and Classes
- The star symbol on fire extinguishers indicates suitability for combustible metals or class D fuels.
- Class A fuels include rubber, cloth, wood, and plastics.
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
- The Incident Command System (ICS) can include multiple sectors but operates under one incident commander.
- The National Incident Management System (NIMS) provides a consistent process for incident preparedness and recovery.
OSHA Standards
- OSHA mandates protection measures for trench work at four feet deep to prevent collapse.
- Bloodborne Pathogen programs are developed by OSHA to maintain safety in the workplace.
Rescue Rope Classification
- Rescue ropes are categorized into three classes: life rescue, non-life safety, and throw line (accessory cord).
- Non-life safety ropes and throw lines have specific applications in rescue scenarios.
Miscellaneous Fire Safety Facts
- Acetylene has the widest flammable range, spanning 2.5% to 100%.
- Carbon dioxide is not classified as a poisonous gas in standard conditions but can be hazardous in high concentrations.
