Study Notes
Flame Spread Classification
- Class A: Flame spread index of 0-25 indicates high resistance to fire spread.
- Class B: Flame spread index of 26-75 denotes moderate fire resistance.
- Class C: Flame spread index of 76-200 is less resistant, typically specified for certain applications.
Smoke Development Index
- Class C: Smoke development index ranges from 0-450, indicating potential smoke production.
Interior Finish Requirements
- Table 803.9 outlines the interior wall and ceiling finish requirements by occupancy type, ensuring safety standards are met.
Space Considerations
- In Group R-2 dwelling units, curtains must not occupy more than 10% of the wall space to avoid excessive fire risk.
Furring Strips Regulations
- Furring strips that are attached directly to a fire-resistance rated structure must not exceed a thickness of 1 3/4 inches to maintain structural integrity in fire situations.
Occupancy-Specific Requirements
- Group I-2 occupancy: Interior finishes must comply with Class B standards if non-sprinklered.
- Group F occupancy:
- In a sprinklered environment, exit stairway finishes must be Class C.
- In a non-sprinklered environment, exit stairway finishes must meet Class B standards.
- Group I-3 occupancy: Requires Class A finishes in exit stairways, reflecting higher safety expectations.
