n accordance with APA procedures, and particularly the Concrete Cutting Prior to Excavation Flowchart process, the Metro Utilities crew made a decision to isolate gas supply prior to cutting concrete due to concerns over a possible shallow service within a Multi User site based on readings from the locator. In accordance with APA procedures, and particularly the Concrete Cutting Prior to Excavation Flowchart process, the Metro Utilities crew made a decision to isolate gas supply prior to cutting concrete due to concerns over a possible shallow service within a Multi User site based on readings from the locator.

Following cutting and removal of the concrete multiple instances of shallow gas services were found within the unit site and the concut blade did actually contact the isolated gas service at Unit 6. The proactive actions of the crew to isolate gas supply prior to cutting the concrete prevented this becoming a Level 3 asset strike and exposing the workers to a hazardous situation. It also reinforces our belief that every asset strike is preventable.
