What is BS EN 60079-29-2 - EA gas detectors standard about?
Safety is a prime concern around flammable gases. Flammable gas detection equipment may be used whenever there is the possibility of a hazard to life or property caused by the accumulation of a flammable gas-air mixture. Such equipment can provide a means of reducing the hazard by detecting the presence of a flammable gas and issuing suitable audible or visual warnings. Gas detectors may also be used to initiate precautionary steps (for example plant shutdown, evacuation, and operation of fire extinguishing procedures).
BS EN 60079-29-2 gives guidance on, and recommended practice for, the selection, installation, safe use and maintenance of electrically operated Group II equipment intended for use in industrial and commercial safety applications and Group I equipment in underground coal mines for the detection and measurement of flammable gases complying with the requirements of BS EN 60079-29-1 or BS EN 60079-29-4.
Note: For these scope exclusions based on enclosure constructions, it is anticipated that the enclosures are not opened in the explosive atmosphere, so that ingress is protected.
Who is BS EN 60079-29-2 - EA gas detectors standard for?
BS EN 60079-29-2 on EA gas detectors standard is useful for:
- Manufacturers of gas detectors
- Operators of mines and refineries
- Concerned maintenance teams
- Product development teams
- Quality control teams
- Health and safety bodies
Why should you use BS EN 60079-29-2 - EA gas detectors standard?
BS EN 60079-29-2 is applicable for oxygen measurement for the purpose of inertisation where explosion protection is provided by the exclusion of oxygen instead of measuring the flammable gases or vapours present. A similar application is measuring oxygen when inertising a goaf (mined out) area in an underground coal mine.
BS EN 60079-29-2 is a compilation of practical knowledge to assist the user, and applies to equipment, instruments and systems that indicate the presence of a flammable or potentially explosive mixture of gas or vapour with air by using an electrical signal from a gas sensor to produce a meter reading, to activate a visual or audible pre-set alarm or other device, or any combination of these. BS EN 60079-29-2 applies to Group II equipment (i.e. equipment intended for use in industrial and commercial safety applications, involving areas classified in accordance with IEC 60079-10-1) and Group I equipment.
Using BS EN 60079-29-2 guidelines, you can select, install, use, and maintain gas detectors for flammable gasses and oxygen intended for use in explosive atmospheres and mitigate hazards such as explosion, fire, electrical, and poisonous gas hazards. BS EN 60079-5 guidelines help you to comply with safety requirements.
