What should be done with drains, scuppers, and bilges in the vicinity of a hot work site that could allow sparks or hot slag to fall into an area containing flammable residue?

A. Covering drains is unnecessary if the work is on an open deck

B. Only the deck surface directly under the work needs to be checked

C. They can be ignored since sparks rarely travel that far

D. They should be checked, cleaned of flammable residue, and covered or otherwise protected as part of the pre-work preparation, not overlooked because they are "out of the direct line of work"

A. Any task lasting longer than 30 minutes

B. Only welding using electric arc equipment

C. Any work involving an open flame, welding, burning, grinding, or any process that produces sufficient heat or sparks to act as a source of ignition for flammable materials, gases, or vapours

D. Only work carried out inside a cargo tank

A. A clear radius of at least 10 metres (or as defined by the risk assessment for the specific task and materials), with all combustibles removed or adequately shielded

B. No clearance is needed if a fire extinguisher is present

C. Clearance is only relevant for work carried out in an engine room

D. 1 metre is always sufficient regardless of the work type
