A crew member asks the Chief Officer what 'reasonably practicable' actually means in the context of risk assessment — it appears throughout the SMS and the regulations but isn't always explained. What's an accurate way to describe it?

A. It means doing the minimum required to avoid an immediate visible hazard, with no obligation to consider less obvious risks

B. It means weighing the level of risk against the cost, time, or effort needed to reduce it further — further precautions are expected unless the sacrifice involved would be grossly disproportionate to the risk reduction actually gained, not simply whenever a precaution is inconvenient or costly

C. It means following whatever the cheapest available option is, provided it technically addresses the hazard

D. It means doing whatever is physically possible, regardless of cost, time, or effort involved

A. Daily, weekly, monthly, and annual risk assessments, based purely on time interval

B. Low, medium, high, and critical risk assessments, based only on severity rating

C. Generic risk assessments (company-level), task-based risk assessments (onboard, specific to the job), toolbox talks (discussing the assessment with those doing the work), and personal/dynamic assessment (an individual's ongoing informal check while working)

D. Deck, engine, catering, and bridge risk assessments, based on department

A. Nothing further — the generic company risk assessment for enclosed space entry already covers this job

B. Only a toolbox talk is needed, since the team already knows the general hazards of enclosed spaces

C. A new generic risk assessment must be drafted and submitted to the company before this job can proceed

D. A task-based risk assessment specific to this entry and these personnel, followed by a toolbox talk walking the team through its findings before work begins
