Close Call/Serious Incident

Location: 
Campbell River
Date of Incident / Close Call: 
2007-01-30
Company Name: 
Strathcona Contracting Ltd.
Details of Incident / Close Call: 

Drill swamper was retrieving the drill hole cones from the front of the tank drill where they had been placed as the operator continued to drill. The drill hammer hose ruptured at the fitting where it leaves the machine and blew off the fitting taking the whip check with it. The whip check, a device utilized to prevent the “fly-away” behaviour of air lines under pressure was improperly anchored and did not function. The drill swamper’s hard hat was struck by the whip check as it was propelled thru the air before coming to rest. This was a close call incident with no injury to workers.

Learnings and Suggestions: 

1) Drill crews to ensure correct placement of whip checks during prework inspections.
2) Anchor points must be visible, allowing for visual inspections by drill crews as well as maintenance personnel.
3) Drill crews to perform routine tug test on whip check to confirm security of attachment.
4) Suspect whip checks must be replaced or repositioned prior to commencement of work.
5) All workers to be aware of the potential hazards of working in close proximity to high pressure air lines.
