Description

This standard gives guidance for identifying and investigating spillage, leakage or build-up of combustion products from gas-fired appliances in non-domestic premises. It gives recommendations for determining the combustion performance of such equipment, using electronic portable combustion gas analysers. This involves sampling and measuring the carbon monoxide (CO) and carbon dioxide (CO₂) in the ambient air and in gas-fired appliance chimneys.

This standard is for use with equipment using 1st, 2nd or 3rd family gases.

NOTE 1 An operative attending non-domestic premises might be required to examine standard gas-fired appliances which are domestic or commercial as well as customized process plant/equipment.

NOTE 2 This standard does not cover the response of an emergency service provider (ESP) to a gas emergency. It also does not cover procedures for investigating incidents that are reportable under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 1995 (RIDDOR) [1] and the Gas Safety (Management) Regulations 1996 (GSMR) [2].

NOTE 3 Combustion products from gas-fired appliances contain aldehydes and oxides of nitrogen (NOx), predominantly nitrogen monoxide (nitric oxide, NO) and nitrogen dioxide (NO₂). Although this standard does not cover the measurement of these substances, quantities of such products could be present in the air and could cause harm and irritation to humans. For guidance on the health considerations associated with these combustion products, see the Institute for Environment and Health assessment,Indoor air quality in the home: Nitrogen dioxide, formaldehyde, volatile organic compounds, house dust mites, fungi and bacteria [3].
