On-site Equipment Safety Checks (CP7 and GN7)

Gas welding and cutting equipment must be checked regularly. The British Compressed Gases Association (BCGA) Code of Practice 7 (CP7 -The Safe Use of Oxy-Fuel Gas Equipment) and Guidance Note 7 (GN7 - The Safe Use of Individual Portable or Mobile Cylinder Gas Supply Equipment) recommend that regulators and flashback arrestors are checked annually and replaced every five years.

Checks need to be undertaken by a person who has sufficient practical experience of oxy-fuel gas equipment as well as theoretical knowledge of the functioning of the equipment, the properties of gases used, the potential defects and hazards that may occur and their importance to the integrity and safety of the equipment.


BOC CP7 and GN7 Checks

BOC CP7 and GN7 checks are performed by a qualified BOC Industrial Inspector (certified by City and Guilds). The inspection includes:

  • a thorough functionality and leak test of all components - regulators, flashback arrestors, hoses, torches and associated fittings
  • a full report of the inspector's findings
  • an update by the inspector on current Health and Safety and BCGA Codes of Practice
