BS 6172: Cooker Ventilation & Stability
Common gas cooker safety defects
The recognised faults that turn an ordinary cooker into a hazard.
Flame supervision devices on hobs and ovens
What a flame supervision device does on a cooking appliance and why a faulty one is a safety concern.
Flexible cooker connections, bayonet hoses and stability restraints
Installation requirements for gas cookers under BS 6172.
Gas cookers, room air and ventilation
Why a kitchen with a gas cooker needs adequate air and an openable window, and what to check.
Cooker Installation, Clearances and Stability
Cooker Flame Picture, Combustion and Commissioning
Connect CKR1 cooker questions to the safety check
In a cooker or hob scenario, identify the appliance and the stated installation conditions before choosing a response. Revise stability, connections, ventilation and flame supervision together, then explain what evidence each check provides.
The CKR1 revision guide gives a route through these topics. Use the flame supervision device guide to distinguish detecting flame failure from other protections, and revisit core gas practice when a cooker question exposes a gap in the underlying safety principles.
