Smoke Clearance Service Testing For Spray Booths

Smoke is most likely to linger and form eddies close to all the walls of a downdraft spray booth; in a room, the smoke will mix with the air and dilute evenly.

By disabling the extraction before filling the room with smoke a maximum clearance time is measured. As the extraction is usually running during normal spraying operations, the clearance time may be less than this but as a safety margin, it is important that the maximum time is observed.

The Smoke Testing Process:

  • Extraction off – Lights on
  • Smoke machine on
  • 2 minutes…
  • Smoke machine off – White out
  • Start extraction & timer
  • Inspect seals & ducting for leakage
  • Smoke clear – Test complete
  • Certicate for display

Smoke clearance testing is essential for ensuring safety in buildings. This process evaluates the effectiveness of smoke control systems during a fire. It plays a crucial role in maintaining visibility and breathable air for occupants. Moreover, it aids firefighters in navigating buildings efficiently.

Smoke control systems are designed to limit the spread of smoke and maintain safe evacuation routes. These systems include smoke vents, pressurisation fans, and exhaust systems. During a smoke clearance test, these components are assessed to ensure they function as intended in an emergency.

Smoke clearance testing is vital for multiple reasons. First, it ensures compliance with safety regulations. The HSE mandate these tests to verify that smoke control systems work properly. Additionally, it protects lives by maintaining clear escape routes during emergencies. Without effective smoke clearance, smoke can quickly obscure visibility and hinder evacuation efforts.

Another critical aspect is the protection of property. Smoke can cause extensive damage to building contents, leading to significant financial losses. Effective smoke clearance systems help minimise this damage by controlling the spread of smoke. Furthermore, smoke clearance testing can reveal weaknesses in the building’s design or system, allowing for improvements before a real emergency occurs.

Regular smoke clearance testing offers numerous benefits. Primarily, it enhances the safety of building occupants. By ensuring that smoke control systems are working correctly, the risk of smoke-related injuries is minimised. Additionally, it helps maintain compliance with local fire safety codes, avoiding potential fines or legal issues.

Another benefit is the reassurance it provides to building owners and occupants. Knowing that the smoke control system has been tested and is functioning correctly gives peace of mind. It also demonstrates a commitment to safety, which can be a significant factor in attracting and retaining tenants.

Regular testing can also extend the lifespan of the smoke control system. Identifying and addressing minor issues early can prevent them from becoming major problems. This proactive maintenance approach can save money in the long run by reducing repair and replacement costs.

HSG261 mandates that spray booth ventilation systems undergo a smoke clearance test every 14 months. This requirement aligns with the Control of Substances Hazardous to Health (COSHH) Regulations, which aim to protect workers from health risks arising from hazardous substances in the workplace.

After struggling to source the filters for some time (with other companies) I tried C-Air Filtration. Their prompt service delivered me a quote for the filters very quickly, and gave me in-depth bespoke advice on filter change procedures for the specific filter in question such as dealing with the safe-change bags etc.After processing the quote the filters came, well within the lead time. They were the correct specification and size.Brilliant service, I would highly recommend.
