scope:

This Standard provides requirements for the design and application of various air flow and air quality interlock devices and associated systems used in conjunction with gas appliance installations in new commercial catering establishments, (see Figure 1).

Note 1: Catering establishments will normally fall within the definition of a 'Food Business' in The Food Safety (General Food Hygiene) Regulations.

Note 2: This Standard does not apply to mobile catering installations or transportable temporary event catering installations. See Liquid Gas UK CoP 24, Part 3.

This Standard applies to replacement of, or extension to, existing installations. It is not retrospective, but it is recommended that existing installations be modified to meet this Standard, when appropriate.

Note: Standards rarely cover the retrospective issue of existing installations. They can, however, set a basis for consideration of performance upon which a risk assessment can be developed. Where appropriate, regular ventilation checks for CO2 levels need to be performed to maintain safety.

It can be argued that any improvements in safety are better than none at all. It may be unreasonable to expect that an old installation is brought right up-to-date in all respects. Where a major refurbishment of the installation takes place, it would be reasonable to consider the installation as a new installation.

This Standard provides the requirements for air quality testing of new and existing commercial catering establishments.

This Standard applies to installations of maximum operating pressure (MOP) not exceeding 100 mbar supplied with Towns (manufactured) gas, Natural Gas (NG), Liquefied Petroleum Gas (LPG), LPG/air, or biogases.

Pressures quoted are gauge pressures unless otherwise stated.

Italicised text is informative and does not represent formal requirements.

Appendices are informative and do not represent formal requirements unless specifically referenced in the main sections via the prescriptive terms "must", "shall" or "should".
