The frequency of air testing smoke shafts

The frequency of air testing smoke shafts can depend on many scenarios, so it can be a complicated answer. The frequency of smoke shaft air testing depends on various factors, including building regulations, insurance requirements and the specific characteristics of the building. Here are some general guidelines:

  • New Buildings or Major Renovations: For newly constructed buildings or significant renovations, newly installed smoke shafts should undergo initial testing to verify their airtightness. This ensures compliance with safety standards and confirms that the smoke shafts will function effectively during emergencies.
  • Periodic Testing and Regular Maintenance: After the initial test, smoke shafts should be retested periodically to ensure ongoing airtightness. The frequency of retesting can vary but is typically recommended every 12 months. Regular maintenance and inspections help identify any deterioration or damage that may compromise the shaft’s performance.


Works to smoke shafts that require additional air testing

Works to the Smoke Shaft: Certain events may require additional testing:

  • Alterations to the smoke shaft: If modifications are made to the fabric of the smoke shaft or adjacent areas, retesting is necessary.
  • Fire Incidents: After a fire incident, smoke shafts should be inspected and tested to confirm their ongoing integrity.
  • Building Occupancy Changes: If the building’s use changes significantly, retesting may be required, i.e. an office building to residential.
  • Consult Local Authorities and Experts: Always consult with local fire safety authorities, building control officers, or fire engineers. They can provide specific guidance based on regional regulations and best practices.

Remember that maintaining properly functioning smoke shafts is essential for occupant safety during fires. Regular air testing ensures their reliability and effectiveness in smoke extraction.
