Elements and Performance Criteria
- Prepare to conduct testing.
- OHS policies and procedures for preparing to work in an area where a potentially explosive atmosphere may be present are followed.
- Area classification is ascertained from the hazardous area layout drawings or other classification documents.
- Location of each item of equipment and of circuits subject to testing is determined from design drawings and documentation.
- Special tools, equipment and testing devices needed for the testing work are obtained and checked for correct operation and safety.
- Conduct testing.
- OHS policies and procedures for working in a hazardous area are followed.
- Parts of equipment that are dismantled in order to conduct testing are stored to protect them against loss or damage.
- Certified and approved low energy testing devices are selected and used to test into areas where explosive hazard may be present.
- Sensitive circuit components that require to be tested which are likely to be damaged by high-test voltages are tested by an appropriate testing method.
- Tests necessary to determine whether the electrical system complies with requirements for the explosion-protection techniques to be used and for electrical safety are conducted in accordance with established procedures.
- When testing has been completed, equipment parts and circuit connections are replaced in a manner that ensures the integrity of the explosion-protection system.
- Confirm and document test results.
- Non-conformances and faults revealed by the testing and the resulting recommended actions are documented and reported to appropriate personnel.
- Completion of testing is verified and a copy of the testing documentation submitted to the appropriate personnel for inclusion in the verification dossier in accordance with established procedures.
