Specifies requirements for the introduction, inspection and maintenance of gas detection and monitoring equipment used in coal mines.

This Standard sets out requirements for the inspection, maintenance and performance verification of gas detection and monitoring equipment that forms, or is a part of, a coal mine’s safety system.
This Standard is applicable to the following:
(a) Equipment that includes sensors to measure or monitor —
(i) Group I flammable gases at concentrations below, within, or above the explosive range;
(ii) toxic gases; and
(iii) oxygen.
(b) Equipment that is —
(i) portable—handheld;
(ii) machine mounted;
(iii) fixed and transportable.
(c) Equipment included in —
(i) tube bundle systems; and
(ii) gas chromatographic systems.
This Standard is not applicable to equipment used for monitoring or reporting of environmental emissions.
While this Standard addresses coal mine applications, the principles are also applicable to other mining applications where toxic gases may present operational hazards.
Section 2 describes the general requirements for inspection, maintenance and user servicing of gas detection and monitoring apparatus.
Section 3 sets out the schedule of inspections and tests applicable to various classifications of gas detection apparatus.
Section 4 describes the individual inspections and tests, the acceptance criteria, and the corrective actions applicable to portable handheld, machine mounted, fixed and transportable gas detectors.
Section 5 describes the individual inspections and tests, the acceptance criteria, and the corrective actions applicable to tube bundle and gas chromatograph systems.
Appendix A sets out the prescribed accuracies for various classes of gas detectors.
NOTE: Appendices B, C, D, E and F provide guidance on good practice for aspects of the installation, inspection and maintenance of gas detection and monitoring equipment.
