A crew member wants to do a "quick" five-minute grinding job to remove a rusted bolt, without raising a hot work permit, reasoning that grinding "isn't really" hot work. Is this correct?

A. No — grinding produces sparks capable of igniting flammable materials/atmosphere and is hot work regardless of job duration; a permit is still required

B. It depends only on which deck the job is carried out on

C. Yes, provided the job takes less than ten minutes

D. Yes — only welding and gas cutting require a permit, not grinding

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
