SMOKE VENTS

Servicing your AOVs (Automatic Opening Vents) is a critical safety requirement in the UK, essential for maintaining smoke control during a fire, ensuring legal compliance, and protecting lives. Several British Standards and UK fire safety laws mandate their regular maintenance.
🔥 WHY IS IT IMPORTANT TO SERVICE YOUR AOVs?
🛡️ 1. Legal Requirement – Regulatory Reform (Fire Safety) Order 2005
Under the Regulatory Reform (Fire Safety) Order 2005 (RRO), the “responsible person” must:
“Ensure that fire safety equipment, including smoke control systems, is maintained in an efficient state, in efficient working order and in good repair.”
Failing to maintain AOVs could result in:
Prosecution or fines
Invalidated insurance
Increased liability if a fire causes injury or death
📘 2. Conformance to British Standards
✅ BS 7346-8
“Code of practice for planning, design, installation, commissioning and maintenance of smoke control systems”
Recommends:
Quarterly inspections
Annual servicing of all smoke control components, including AOVs
Documented evidence of testing and maintenance
Ensures systems work as intended under fire conditions
💨 3. Life Safety and Smoke Management
AOVs are designed to:
Extract smoke and heat from escape routes (e.g., stairwells, corridors)
Improve visibility and breathable air for occupants and firefighters
If an AOV fails due to lack of maintenance, escape routes may fill with smoke, increasing the risk of injury or death
⚙️ 4. Operational Reliability
Regular servicing ensures:
Smoke detection triggers correctly activate AOVs
Backup power supplies (e.g., batteries) are operational
Mechanical parts (actuators, hinges, controls) are clean, lubricated, and functioning
Manual override switches operate as intended
📑 5. Compliance Records and Insurance
Insurers and fire risk assessors may request evidence of regular servicing in line with:
BS 7346-8
Lack of maintenance records can result in:
Invalid insurance claims
Enforcement notices from the fire service
Failure to pass fire risk assessments
✅ Summary
Regular servicing of your AOVs is vital to:
Comply with UK fire safety law (RRO 2005)
Meet the requirements of BS 7346-8
Ensure AOVs operate effectively during fire emergencies
Protect life, property, and legal liability
