Summary: An electrician suffered several electric shocks when a second electrician carried out an insulation test on the cable they were working on. The electricians were at opposite ends of the cable and the electrician conducting the insulation test did not communicate his intended actions.
Recommendations to industry: A procedure should be in place for the use of electrical test equipment, including the exposure to workers.
Clear communication is required between work parties and team members. The potential impact of the task on other workers should be considered in procedures and risk assessments.
