An OOW supervising a job performs a personal/dynamic risk assessment partway through and isn't confident the current controls are adequate given how the job has evolved. What should happen next, according to the structure of the four-level process?

A. If the dynamic assessment isn't sufficient to confirm the job remains safe, the OOW should step back to the task-based risk assessment stage — reviewing and, if necessary, formally revising the plan — rather than relying on personal judgement alone to push through

B. The OOW should continue the job and document the concern for review afterward

C. The OOW should delegate the decision to whichever crew member raised the concern first

D. The OOW should proceed based on personal judgement alone, since dynamic assessment is designed to be the final word

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
