Does SANS 10400-T compliance only apply at construction?

No. SANS 10400-T governs the ongoing condition of fire protection in your building for as long as it is occupied. A building that was compliant at construction can become non-compliant through neglect, modification, or a change in use.

What are the consequences of SANS 10400-T non-compliance?

Non-compliance can result in improvement or prohibition notices from DOL inspectors or fire officials, potential prosecution under the OHS Act, and grounds for insurers to contest fire claims.

SANS 10400-T Fire Compliance: What Your Building Must Have

Q: What is SANS 10400-T?

SANS 10400-T is Part T (Fire Protection) of the South African National Standard for the National Building Regulations. It is the primary standard used by local authority building control officials to assess fire protection compliance in all non-domestic buildings.

Q: Which buildings does SANS 10400-T apply to?

SANS 10400-T applies to all non-domestic buildings — offices, warehouses, factories, hotels, hospitals, schools, shopping centres, data centres, and mixed-use developments. It does not apply to private dwelling houses.

Q: How often must fire protection systems be inspected?

SANS 10139 (referenced by SANS 10400-T) requires six-monthly maintenance on fire detection and alarm systems. Other systems have their own intervals — fire extinguishers annually, hose reels annually, and sprinkler systems per SANS 1475 and SANS 543 respectively.

If your building has ever been inspected by a fire official, received a non-compliance notice, or had an insurer query your fire protection — SANS 10400-T is almost certainly the standard at the centre of it. Yet most building owners and facilities managers have never actually read it.

This guide breaks down what SANS 10400-T requires in plain language, which systems it governs, and what it means for your specific building type. By the end, you will know exactly what you are legally required to have — and the questions to ask if you're not sure you have it.

What Is SANS 10400-T?

SANS 10400-T is Part T (Fire Protection) of the South African National Standard for the application of the National Building Regulations. It is adopted under the National Building Regulations and Building Standards Act No. 103 of 1977 and is the primary technical standard that local authority building control officials use when assessing fire protection compliance.

In practical terms, it is the standard that determines whether your building receives a Certificate of Occupancy — and whether that certificate can be revoked if your building falls out of compliance. It does not stand alone: SANS 10400-T references SANS 10139 for fire detection and alarm systems, SANS 23601 for escape plans, and SANS 14520 for gas suppression systems.

Critical point: SANS 10400-T is not a checklist you complete once at construction. It governs the ongoing condition of fire protection in your building for as long as it is occupied. A system that was compliant at construction can become non-compliant through neglect, modification, or a change in use.

Which Buildings Does SANS 10400-T Apply To?

SANS 10400-T applies to all non-domestic buildings — every building that is not a private dwelling house. This includes offices, warehouses, factories, hotels, hospitals, schools, shopping centres, data centres, and mixed-use developments.

The specific requirements differ by occupancy classification. Your classification determines fire resistance ratings, required exits, corridor widths, and which suppression systems are mandatory.

Classification	Building Type
A1 / A2 / A3	Entertainment, amusement, places of instruction
B1 / B2	Institutional — hospitals, care facilities, prisons
D1 – D4	Large, medium and small shops; wholesale markets
E1 – E4	Industrial occupancies by hazard level
F1 – F3	Storage occupancies by hazard level
G1	Offices
H1 – H5	Residential occupancies above single dwelling

Important: If your building's use has changed since it was originally classified — even partially — your compliance status may have changed with it. A warehouse converted to offices, or a factory now partly used for retail, may need re-assessment.

The Six Core SANS 10400-T Requirements

Fire Resistance of Structural Elements

SANS 10400-T specifies the minimum fire resistance rating (in hours) for structural walls, floors, columns, beams, and roof assemblies. Structural modifications, penetrations through fire-rated walls, and removal of fire-rated linings during renovations can all compromise compliance in existing buildings.

Common failure: Fire-rated linings removed during renovation and not reinstated

Compartmentation

Fire compartmentation divides a building into sections that resist the spread of fire and smoke. Every penetration through a fire-rated wall or floor — pipes, cables, ducts — must be fire-stopped to maintain compartment integrity. In practice, compartmentation failures are extremely common wherever services have been added over time.

Common failure: Unsealed cable and pipe penetrations after installation work

Means of Escape

SANS 10400-T specifies travel distances to exits, exit quantities and widths, corridor widths, door swing directions, and exit signage. Maximum travel distance to the nearest exit is typically 45m for sprinklered buildings and 30m for unsprinklered. Minimum exit door width is 850mm clear opening. Escape routes must be served by emergency lighting, and SANS 23601-compliant escape plans must be displayed at strategic locations.

Common failure: Exit doors locked during working hours; emergency lighting not maintained

Fire Detection and Alarm Systems

Where a system is required, it must comply with SANS 10139:2021 — which specifies system categories (M, L1–L5, P1–P2), design certification, installation certification, commissioning certification, and ongoing six-monthly maintenance. A smoke detector connected to a siren is not a SANS 10139-compliant system. Compliance requires a declared system category, certified design, certified installation, and documented maintenance history.

Common failure: No declared system category; no maintenance certificates on file

Fire Suppression and Firefighting Equipment

Depending on occupancy and building size, SANS 10400-T may require: portable fire extinguishers (type and coverage per SANS 10105 and SANS 1475), fire hose reels with 36m hose coverage to all points per SANS 543, fire hydrant systems per SANS 1128, automatic sprinkler systems for buildings above certain size thresholds, and gas suppression systems for specific high-risk enclosures per SANS 14520.

Common failure: Wrong extinguisher type for fire risk; hose reel coverage gaps

Fire Brigade Access

SANS 10400-T requires fire brigade vehicles to access the building perimeter with minimum road widths, turning circles, and clear zones. For taller buildings, wet or dry riser systems must allow fire brigade hose connections at each floor level.

Common failure: Access routes blocked by permanent structures or parking; no riser system in multi-storey buildings

The 8 Most Common SANS 10400-T Failures

Based on compliance assessments across commercial, industrial, and institutional premises in South Africa, these are the failures encountered most frequently:

01Fire detection system with no declared SANS 10139 category and no maintenance certificates
02Fire doors propped open or mechanically modified — directly compromising compartmentation
03Penetrations through fire-rated walls and floors left unsealed after cabling or pipe installation
04Hose reel coverage gaps — areas more than 36m from any reel with no alternative coverage
05Escape plans either absent or non-compliant with SANS 23601
06Fire extinguishers of the wrong type for the fire risk present in that area
07Emergency lighting not tested or failed lamps not replaced
08Exit doors locked or obstructed during working hours

Compliant vs. Non-Compliant: What the Difference Looks Like

✕ Non-Compliant Building

Smoke detectors wired to a siren — no certified system category
Fire doors propped open with wedges or cable reels
Unsealed penetrations through fire-rated walls
Hose reel mounted in one location only — coverage gaps throughout
Escape plans absent or printed in black and white on A4
CO₂ extinguishers in a kitchen — wrong type for cooking oil fires
Emergency light fittings present but untested
Stairwell exit door locked after hours — no key accessible

✓ SANS 10400-T Compliant

Certified SANS 10139 system with six-monthly maintenance records
Self-closing fire doors on rated compartment boundaries
All penetrations fire-stopped with certified intumescent materials
Hose reels positioned to provide 36m coverage to all floor areas
SANS 23601-compliant colour escape plans at all key positions
Correct extinguisher types matched to fire risk classification
Emergency lighting tested monthly, serviced annually
All exit doors openable from inside at all times building is occupied

Legal and Insurance Consequences of Non-Compliance

Legal: DOL inspectors and fire officials identify non-compliant systems and issue improvement notices requiring immediate rectification. Non-compliance can escalate to prohibition notices — stopping all operations — and prosecution under the OHS Act 85 of 1993.

Insurance: A fire incident investigation revealing non-compliant systems gives insurers documented grounds to contest claims and challenge coverage. An insurer finding that your fire detection system had no maintenance records, or that fire doors were propped open, is an insurer with grounds to decline your claim.

What happens when use changes: If your building or any section of it changes occupancy classification — warehouse to office, factory to retail — you are legally required to re-assess compliance against the new classification. This is frequently missed, and frequently discovered only during an inspection.

Frequently Asked Questions

What is the difference between SANS 10400-T and the OHS Act? +

SANS 10400-T is the technical standard that defines what fire protection systems your building must have. The OHS Act 85 of 1993 is the law that creates the legal obligation on employers to maintain a safe working environment. SANS 10400-T is referenced and enforced through both the National Building Regulations and the OHS Act — non-compliance with SANS 10400-T can constitute a breach of the OHS Act.

Does SANS 10400-T compliance only apply at the point of construction? +

No. SANS 10400-T governs the ongoing condition of fire protection in your building for as long as it is occupied. A building that was fully compliant at the time of construction can become non-compliant years later through neglect of maintenance, building modifications, or a change in the building's use or occupancy classification.

How often must fire protection systems be inspected and maintained? +

Inspection and maintenance intervals depend on the system. SANS 10139 (fire detection) requires six-monthly maintenance by a certified service provider. Fire extinguishers require annual service per SANS 1475. Hose reels require annual inspection per SANS 543. Sprinkler systems are maintained per the relevant SANS standard for the system type. All maintenance must be documented — certificates on file are what an inspector will ask for.

What happens if a DOL inspector finds my building non-compliant? +

A DOL inspector finding non-compliance will typically issue an improvement notice specifying the deficiencies and a rectification deadline. Failure to meet that deadline can escalate to a prohibition notice — which can stop operations in the affected area or the entire building. Repeat or serious non-compliance can result in prosecution of the employer or responsible person under the OHS Act.

My building is old — does SANS 10400-T still apply? +

Yes. While buildings constructed before the current version of SANS 10400-T came into effect are not automatically required to be upgraded to new construction standards, the OHS Act obligation to maintain a safe working environment applies regardless of building age. In practice, any building undergoing inspection is assessed against the current standard — and any significant renovation triggers a full re-assessment.
