Passive and active fire protection in structural fire strategy — Ch. 37 orientation.

Scope

CivilTech notes on structural fire behaviour and design. Not a substitute for project codes, approvals, or peer review.

Regulatory context. South African projects follow National Building Regulations, SANS 10400, and cited material standards; use this material as orientation only.

Using this page

  1. Context — Cross-check these notes with your project fire strategy and the code edition on the job.
  2. Tools — The Fire Engineering page has ISO 834 and steel-retention calculators for quick checks.
  3. Approval — Fire resistance and structural fire design remain subject to the local authority and appointed engineers.

Fire engineering — Protection systems

Section 8 — Passive measures delay heating of structure; active measures detect and suppress or control fire growth.

Passive protection

Intumescent coatings, boards, sprays, and enclosures increase insulation; detailing at connections and penetrations is critical for continuity.

Active protection

Sprinklers can reduce severity or delay flashover; detection and alarm support evacuation. Interaction with structural fire strategy must be coordinated.
