Restaurant ventilation fire requirements: controls, tests and records

Restaurant extraction involves more than airflow. Plan ventilation controls, fire-system interfaces and licensing documents together before closing ceilings or arranging tests.

If there is fire or immediate danger

Leave the premises using a safe route and call Hong Kong emergency services on 999. Do not remain to investigate or use a lift.

Legal information

This guide helps with initial planning; it is not legal advice or an engineering assessment of your premises. Confirm the requirements against the use, approved plans, licence conditions, written directions and current official documents.

Quick answers

Does FS251 mean all ventilation licensing documents are complete?

No. Check the issued fire and ventilation requirements individually and confirm the equipment, work and tests covered by each document.

Identify extraction, ventilation and fire controls

Kitchen extraction, general ventilation and fire-related ventilation controls have different functions. FSD publishes requirements for licensed premises; the team should identify which apply to the actual system and issued conditions.

Put fans, ducts, controls and fire-system connections into one coordinated schedule. Identify tenant and shared-building equipment early so access and responsibility can be agreed before installation.

Arrange joint testing of connected systems

The fire-control function concerns how ventilation equipment responds to the relevant signal. Appropriate contractors should test against the accepted design; normal fan operation alone does not demonstrate the fire-control function.

Before testing, agree the time, affected areas and reinstatement plan with management and both contractors. Explain any tenant coordination in advance and record who will verify that normal operation has resumed.

Check access before closing ceilings and collect records

Before ceilings are closed, photograph key equipment, access panels and labels, and update the drawings. This gives future maintenance teams a usable record and helps avoid unnecessary opening-up work.

At handover, collect the fire and ventilation certificates, reports and maintenance information applicable to the project. If older records differ from the completed layout, resolve those differences and agree the updates needed.

Practical checklist

  • Current duct and fire-equipment drawings
  • Fan, control and equipment details
  • Tenant and common-system boundaries
  • Shutdown, interface-test and reinstatement windows
  • Documents and maintenance contacts for each trade

Discuss restaurant fire and ventilation coordination

Share existing or proposed extraction drawings, issued requirements and the works programme so we can discuss coordination and testing.

  • Review fire signals and equipment interfaces
  • Coordinate testing with the ventilation contractor
  • Follow up alterations, records and documents
