Fire Doors & Life Safety

Specify hose-valve and extinguisher cabinet doors by cabinet type, door style, glazing, lettering, access hardware and wall-mounting requirements.

Maximum vision panel sizes by fire rating under IBC/NFPA 80 and EN routes, glazing types, and the 100 sq in rules that catch buyers out.

Where codes require panic or fire exit hardware by occupancy and occupant load, listing marks to check, and door-swing rules that pair with them.

When fire and smoke doors must self-close and latch, hold-open exceptions, closer sizing basics and inspection failures that recur most.

How AS 1530.4 testing produces an FRL, how AS 1905.1 governs the doorset itself, and how to check a test or assessment report before buying.

What BS 476 Part 22 covers, where FD30/FD60 classifications stand today, and how UK projects are moving to EN 1634-1 and EN 13501-2 evidence.

Paint alone cannot certify a door. What actually creates a fire rating, when upgrade systems help, and when only a listed doorset is acceptable.

EI30, EI60 and EI90 compared: integrity plus insulation, typical wall pairings, thickness and cost impact, and US/UK/AU rating equivalents.

How EN 1634-1 testing works, how results become EI/E classes under EN 13501-2, and what a usable test or classification report must contain.

UL 10B tests at neutral pressure, UL 10C at positive pressure. Why the difference changes seals, Category A/B doors and what specs to request.

Use IBC Table 716.1(2) correctly: required door ratings by wall type, vision panel limits and temperature-rise rules, with edition notes.

What NFPA 105 requires for smoke door assemblies: UL 1784 leakage limits, gasketing, labeling and inspection duties, and how it pairs with NFPA 80.
