Smoke Shaft Testing
Safeguarding Lives and Buildings Through Effective Smoke Control.
In the event of a fire, smoke poses a significant threat to life and property. It can spread rapidly, obscure escape routes, and impede firefighting efforts. This is why effective smoke control systems, including smoke shafts, are critical components of any building’s fire safety strategy.
What are Smoke Shafts?
Smoke shafts are vertical ducts that are designed to extract smoke from a building in the event of a fire. They work in conjunction with fire detection and alarm systems, as well as other ventilation components, to create a safe and effective smoke evacuation path. This helps to:
- Protect Escape Routes: Smoke shafts prevent smoke from filling stairwells and corridors, ensuring that occupants have a clear path to safety.
- Facilitate Firefighting: By removing smoke, firefighters have better visibility and can access the source of the fire more easily.
- Reduce Property Damage: Minimising smoke spread can significantly reduce the extent of damage caused by smoke and heat.
Smoke Shafts and UK Building Regulations: A Legal Framework for Safety
In the UK, smoke control systems, including smoke shafts, are subject to stringent regulations designed to ensure the safety of building occupants in the event of a fire. These regulations are primarily outlined in Approved Document B (ADB) of the Building Regulations, with specific guidance on the design, installation, and testing of smoke control systems.
Key Legal Requirements:
- Functional Requirements: ADB outlines the performance requirements for smoke control systems, specifying how they should operate in both normal and fire conditions. This includes requirements for the extraction rate of smoke, the pressure differential within the shaft, and the functionality of components like dampers and fans.
- System Design: Smoke shafts must be designed to effectively extract smoke from the building, taking into account factors like the height of the building, the number of floors, and the type of occupancy.
- Testing and Commissioning: Building regulations require that smoke control systems undergo rigorous testing and commissioning to verify their performance before a building can be occupied. This includes air tightness testing, functional testing of components, and potentially smoke tests to visualise smoke movement within the shaft.
- Ongoing Maintenance: Once a smoke shaft system is installed, it’s not a “set it and forget it” situation. Regular maintenance and inspections are essential to ensure the system remains operational and compliant with regulations.
The Importance of Compliance
Failing to comply with smoke shaft regulations can have serious consequences:
- Safety Risks: A malfunctioning smoke control system can significantly increase the risk to occupants in the event of a fire. Smoke inhalation is a leading cause of fire-related deaths, and a poorly performing smoke shaft can hinder evacuation and firefighting efforts.
- Legal Penalties: Non-compliance can lead to enforcement action by local authorities, including fines, prohibition notices, or even prosecution.
- Insurance Issues: Your building insurance may be invalidated if your smoke control system doesn’t meet regulatory requirements.
Post-Grenfell Regulatory Landscape
The Grenfell Tower tragedy in 2017 led to a heightened focus on fire safety in the UK. Several changes and updates to building regulations have been implemented or are under consideration, particularly for high-rise residential buildings. While the full impact of these changes on smoke shaft regulations is still unfolding, it’s clear that there will be an even greater emphasis on stringent testing, regular maintenance, and the use of robust, reliable smoke control systems in the future.

Frequently Asked Questions
Smoke shaft testing is typically required for:
New Buildings: Building regulations stipulate that smoke control systems in new buildings must be tested and commissioned before the building is occupied.
Existing Buildings: Regular smoke shaft testing is recommended for existing buildings to ensure ongoing compliance and system performance.
After Modifications: If any modifications are made to a smoke shaft system, such as replacing dampers or fans, retesting is often necessary to verify the effectiveness of the changes.
Yes, smoke shaft testing is a legal requirement for new buildings and is often required for existing buildings as part of ongoing fire safety compliance. Building regulations stipulate that smoke control systems, including smoke shafts, must be tested and commissioned before a building is occupied.
The frequency of smoke shaft testing can vary depending on the type of building and its use. However, as a general guideline, it’s recommended to have smoke shafts tested at least every three years for most commercial buildings. High-rise residential buildings and buildings with complex smoke control systems may require more frequent testing.
If your smoke shaft fails the test, it means that it’s not performing as intended and may not be able to effectively control smoke in the event of a fire. This could pose a serious risk to occupants and property.
In such cases, it’s essential to identify the cause of the failure and take remedial action as soon as possible. This might involve repairing or replacing faulty components, adjusting ventilation settings, or addressing any leaks or blockages in the shaft.
Smoke shaft testing requires specialised knowledge, equipment, and experience. It’s best to leave it to qualified professionals who are trained and certified to conduct these tests in accordance with relevant regulations and standards. Attempting to conduct tests yourself could lead to inaccurate results and may not meet the requirements for compliance.
