• Analysing and interpreting survey results to determine the location of gas escapes
• Understanding gas concentrations and explosive limits
• Priorities when dealing with gas escapes
• Operating and evaluating readings from gas detection equipment
• Search techniques for detecting gas and carbon monoxide leakage
• Evacuation and reoccupation criteria
• Correct use of a voltstick, bar hole tool, and searcher bar
• Checking and using a rock drill and tornado
• Identifying correct PPE requirements
• Locating and applying guidance from EM72, EM74, and EM74A

This course is aimed at gas industry operatives and supervisors who may be required to undertake emergency and remedial work on the UK gas network, particularly those involved in locating and repairing gas escapes.

Learners wishing to undertake this training and assessment must already hold their NCO Gas Level 2 Service Laying or Mains Layer (Distribution) certificate under the Distribution pathway, as ELR registration is not available to those who have completed the Self-Lay pathway.

Employers benefit from more competent employees who are better able to communicate actions to others and remain compliant with industry standards and EUSR registration requirements.
