Elements and Performance Criteria
- Prepare to work in hazardous area.
- Nature of the explosion hazard in the area is known and the status of the explosion hazard is ascertained through established procedures.
- Operation and condition of plant and machinery, with regards to explosion-protection, is ascertained through established procedures.
- Established procedures for use of the plant and machinery, with regards to explosion-protection techniques used in the area, are followed.
- Observe condition of explosion-protection system area.
- OHS policies and procedures, with regards to explosion-protection, are followed.
- Performance of plant and machinery is monitored to identify faults that may affect the integrity of the explosion-protected equipment and wiring system.
- Observations of explosion-protected equipment and wiring are made during normal operations and visual non-conformances that may affect the integrity of the explosion-protection technique are identified.
- Explosion hazard monitoring equipment is observed and a potentially dangerous state of the hazard is identified, e.g. by using gas detectors.
- Take actions to limit risk of an explosion.
- Variations outside normal operating conditions are reported and documented in accordance with established procedures
- Non-conforming tools, equipment and testing devices are reported and documented in accordance with established procedures.
- Established procedures are followed in the event of a potential or immediate hazardous condition arising from any non-conformance identified in equipment/wiring or changes in the explosion hazard to a potentially dangerous state.
