Health & Safety Executive Logo It is a legal requirement to ensure that gas equipment used in the workplace is maintained under the Pressure Systems Safety Regulations, detailed in the Health and Safety at Work Act 1974, equipment should be “suitable”, “maintained” and “inspected”.

The overall intentions of the PSSR is to “prevent serious injury from the hazard of stored energy, as a result of the failure of a pressure system or one of its component parts.”

We provide professional gas equipment safety inspections to organisations and businesses falling under BCGA Code of Practice 7, 39 & 47 in the south of England.

Gas Equipment Safety Inspections
Gas equipment inspections are required to be carried out by those with sufficient training and qualifications in the use of gas equipment.

Proficiency in the theory and practical experience of the functioning of the equipment along with a thorough understanding the properties of the gases in use, is imperative to be able to assess the condition of the equipment, identify defects and hazards that may occur or be present.

Our service engineers are members of the PGS Gas Professional Community and hold a current PGS Passport Card and a Level 3 qualification in mobile oxy-fuel equipment inspection (CP7 & CP47) and in accordance with HSE INDG certification. You can find us listed on the official website.

In order to carry out these inspections safely, all inspectors must be suitably trained to enable them to work safely without risk to the health and safety of both themselves and others. Inspectors who are in possession of a current PGS passport card have undertaken this training.

AES Industrial Supplies Ltd offer our customers a very quick and easy method to avoid the pitfalls associated with gas safety, and comply with the PGS Gas Professional Community by providing you with a full on-site gas equipment safety check performed by our professionally trained gas equipment inspector.

CP7 Gas Inspection

What is CP7?

This Code of Practice gives a guide to the minimum safety standards required for the assembly, examination, inspection, maintenance and use of individual portable or mobile cylinder oxy-fuel gas equipment, each gas being supplied from a cylinder and individually controlled by a cylinder-mounted pressure regulator.

Gas cylinders are designed and constructed to safely contain a gas under pressure. Used with the correct downstream pressure equipment they provide an efficient and effective means of delivering a gas to the end process.

Oxy-fuel gas equipment has many uses, including welding, cutting, heating, straightening, and descaling. The equipment is versatile and relatively easy to move and use, however, it also has its hazards and consequently its use is governed by several Regulations.

CP7 Gas Safety Inspector Passport

What is involved in a CP7 gas inspection?

  • An equipment inspection to help you meet legal requirements and industry code of practice
  • A full report on equipment condition plus certificate of inspection
  • A dynamic risk assessment of your working area
  • A visual and function check of regulators, flashback arrestors, hoses and blowpipes
  • Advice on the handling, storage and transport of gas cylinders and equipment
Importance of CP7 gas safety and legislation

There are several regulatory bodies that are relevant regarding the use of pressure equipment in oxyfuel applications, these are:

  • Pressure Equipment (Safety) Regulations
  • Provision and Use of Work Equipment Regulations 1998
  • Pressure Systems Safety Regulations 2000
  • Acetylene Safety (England and Wales and Scotland) Regulations
  • The Construction (Design and Management) Regulations 2015
  • Dangerous Substances and Explosive Atmospheres Regulations 2002
  • The Control of Substances Hazardous to Health Regulations 2002
  • The Management of Health and Safety at Work Regulations
  • Confined Spaces Regulations
  • Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations
Dangers of CP7 gas

There are a number of significant hazards when using oxy-fuel gases and equipment, these are:

  • Backfire
  • Sustained backfire and intermittent backfire
  • Flashback
  • Backflow
  • Decomposition
  • Ignition within an oxygen system
  • Oxygen leakage
  • Fuel gas leakage
  • Fumes
  • Noise
  • Manual handling


What does CP stand for?

"CP" is short for Code of Practice. The BCGA (British Compressed Gas Association) have 48 CP's in total.

The 48 CP's cover every aspect of gas, from the filling of gas bottles like propane bottles which apply to manufacturers to guidelines covering medical gasses.


How often should CP7 gas inspections take place?

It is recommended that gas control regulators and flashback arrestors should be checked annually and replaced every five years

Differences between CP7, 39 and 47?

CP7 is the guideline for mobile oxy-fule sets, CP47 is for inert gas regulators for welding and CP39 covers the in-service requirements of pressure equipment (gas storage and gas distribution systems) so this includes Manifolds.

"BCGA publications are produced by and for the gases industry, but many are also used by their customers. As BCGA also involve and keep informed government bodies, Competent Authorities and Regulators, such as the Department for Transport and the national Environment Agencies, during the development of these publications they are generally accepted as being an appropriate and safe way of working. As such, they give positive examples of best practice and are recognised for this by the enforcement agencies, such as the Health and Safety Executive. It should be noted that in the event of any legal action, either criminal or civil, the courts are likely to use BCGA documents as a measure of what may be reasonably practicable."
