BS 60080:2020

This standard BS 60080:2020 Explosive and toxic atmospheres. Hazard detection mapping. Guidance on the placement of permanently installed flame and gas detection devices using software tools and other techniques is classified in these ICS categories:

• 29.260.20 Electrical apparatus for explosive atmospheres

This British Standard provides guidance on the placement of permanently-installed F&G detectors, including coverage and technology selection.

NOTE 1 “Permanently-installed detection systems” include optical flame detection (including ultraviolet, infrared and imaging/visual), flammable gas/vapour detection and toxic gas detection.

This British Standard provides guidance on the most commonly used methods of mapping and/or modelling: prescriptive, volumetric-based and scenario-based.

This British Standard is applicable to applications where:

1. optical flame detection is used as a means of detecting flaming fires in internal and external environments;

2. a gas detection system is used as a method of explosion protection;

3. the hazard arises from the release or accumulation of explosive gases and vapours; and

4. the hazard arises from the release or accumulation of toxic gases.

This British Standard also provides guidance on operations, maintenance and the availability/reliability of the system to complement relevant standards.

This British Standard does not provide guidance for:

1. addressing hazards that are a product of vehicle exhaust fumes;

2. applications in the domestic and general public environment;

3. applications in mining and tunnelling, heating ventilation and air conditioning (HVAC), medical applications or environments;

4. smoke detection; or

5. toxic gas detection with regard to business continuity, e.g. food tainting.

Mitigation effectiveness is an important aspect of F&G detection design but is out of scope of this British Standard.

NOTE 2 Oxygen detection is typically biased towards prescriptive methods for detector coverage and is generally excluded from this British Standard, considerations regarding typical oxygen detection are described in Annex A.
