Summary
A vessel’s portable seismic sparker produced sparks at its -5600V terminals during initial testing. Investigation identified incorrect washers and bolt threading that could prevent full tightening. Training time was reduced and reporting delayed four weeks. Recommendations address competence, risk assessments, stopping work, power isolation and prompt investigation.
