2.1 Basis of section
The potential for failure during the pressure test presents a significant hazard to personnel and equipment, the public and the environment. Risk associated with this hazard shall be assessed and CONTROLLED.
2.2 Hazard assessment
Prior to conducting a pressure test, a formal hazard assessment shall be undertaken using an appropriate methodology to identify hazards, failure modes, controls, and to assess residual risks.
The TEST PLAN or the test procedure or both shall be included in this assessment.
The hazard assessment shall consider the consequence of pipeline failure at any point along the length of the test section, particularly at locations where the failure may impact on the public, public facilities, or the environment. If necessary, additional controls shall be applied to manage this risk.
The TEST SIGNATORY shall participate in, and endorse, the hazard assessment.
NOTE 1 For the safety management requirements for a new or an existing pipeline, refer to AS/NZS 2885.1, AS/NZS 2885.3 and AS/NZS 2885.6. An SMS does not replace the field pressure testing hazard assessment. The safety management requirements, for example hazard control methods applied to the design and the field-testing procedures, should be considered in the field-testing procedures and provided to the TEST SIGNATORY.
NOTE 2 One method for reducing risk in areas where failure may impact public, facilities or personnel is to apply the concept of PRELIMINARY TESTS in areas such as road or rail crossings and pipeline sections within manned facilities.
The hazard assessment shall be performed prior to commencement of testing operations to consider the sources of potential harm specific to pressure testing. It shall encompass each aspect of the testing operation and consider the safety of testing personnel, other construction personnel, general public, landholders and any other stakeholders.
The hazard assessment and the method used to conduct the hazard assessment shall be documented. NOTE 3 For further information on safety in pressure testing, see Appendix N.
2.3 Emergency response plan
An emergency response plan shall be prepared for the pressure test. The plan shall address at least the following:
(a) Risk (or hazard) management in place for the test. This will be different for a new pipeline being tested as part of a construction operation than for an in-service test of an existing pipeline.
(b) Emergency events identified from the hazard assessment.
(c) Communication with public authorities and key stakeholders such as landowners.
(d) Personnel safety and response, including medical evacuation.
(e) Environmental response.
The emergency response plan shall be APPROVED. Relevant personnel shall be familiarized with the response plan prior to commencement of the test.
For a new pipeline, the emergency response plan may be a subset olthe construction safety management plan. For an existing pipeline, the emergency response plan may be a part of the LICENSEE’S PIPELINE MANAGEMENT SYSTEM.AS 2885.5 pdf download.
