Summary
An investigation examines welding slag igniting methanol beneath platform hot work, leading to a BLEVE and fires that burnt two workers. It identifies incomplete shielding, restricted tank venting, inadequate fire-watch positioning, permit non-compliance and supervision deficiencies. Operator recommendations address conditional use of two fire watches and removal or treatment of flammable contents.
