Study Notes
Fire Resistance Terms and Concepts
- Fire Resistant: Material that provides increased fire resistance to structural elements or systems.
- Fire Retardant: Substance designed to delay or prevent combustion.
- Fireproof: Indicates material that is resistant to fire effects, often misleading as no material is completely immune to fire.
- Flame Retardant: Similar to fire retardant, specifically formulated to resist flames.
Historical Context
- 1890: Year of the first fire test conducted for a fireproof floor assembly by the Denver Equitable Building Company.
Fire Resistance Ratings
- Rated fire resistance applies to structures like walls, floors, and columns.
- Classifications based on Endurance indicator of materials' fire resistance capabilities.
- Evaluation of fire resistance includes Hours of performance during testing.
Flame Spread Ratings
- Class A: Flame spread rating of 0-25.
- Class B: Flame spread rating of 26-75.
- Class C: Flame spread rating of 76-200.
Testing Standards
- NFPA 255: Recognized standard method for testing surface burning characteristics of building materials.
- Also known as ASTM E-84 or the Steiner tunnel test.
- Flame spread over inorganic reinforced cement board is set at 0, while red oak is set at 100.
Radiant Panel Flame Spread Test
- Measurement involves panels that are 20 × 24 inches.
FM Approvals Corner Test
- Walls can be up to 25 feet high, with the east wall measuring 50 feet and the south wall measuring over 37 feet.
Radiant Flux Test
- NFPA 253 assesses material's resistance to flame spread.
- Result is termed critical radiant flux.
Fire Safety Features
- Fire Dampers: Devices used to limit smoke movement in HVAC systems.
- Common closure methods for fire doors include Swinging doors, with automatic and self-closing variants available.
- Fusible links are installed in fire walls with automatic fire doors to enable closure in fire conditions.
Firefighter Protocols
- When dealing with buildings equipped with sprinkler systems, priority is to Supply the fire department connection.
Types of Standpipe Systems
- Class II standpipes utilize "houselines" meant for occupant use.
Automatic Fire Door Inspection
- Inspections should verify functioning and safety without neglecting measures like height of the operating door.
