Question 1

A planned maintenance job under the Chief Officer's authorisation turns out, once underway, to require work the original risk assessment never considered — entering a confined space that wasn't part of the original scope. Is this still a simple change the team can adjust on the spot?

Accepted Answer

No — discovering an entirely new hazard category (confined space entry) outside the scope of the original assessment is a complex change; the job should stop and a proper task-based risk assessment for the new scope should be carried out, rather than improvising controls on the spot A change that introduces a genuinely new hazard category the original assessment never considered goes beyond what a toolbox-talk-level adjustment can responsibly cover — this calls for stopping work and properly assessing the new scope, treating it as a complex change.

Question 2

A cadet is told that risk assessment on board isn't just one document but happens at four different levels, including something as informal as a quick personal check before starting a task. What are these four levels, broadly?

Accepted Answer

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) COSWP describes a four-level structure: generic risk assessments set by the company, task-based risk assessments (TBRA) carried out onboard for specific jobs, toolbox talks that walk the team through the TBRA before work starts, and personal/dynamic risk assessment carried out informally by the individual as work proceeds.

Question 3

An OOW is about to lead a small team in a non-routine, high-risk job — entry into a void space that hasn't been entered in months. A generic company risk assessment exists for enclosed space entry in general. What additional level(s) of assessment does the OOW need before this specific job can proceed?

Accepted Answer

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 Generic risk assessments don't capture ship- and task-specific factors at the time of the job — a non-routine, high-risk task like this needs its own task-based risk assessment, with a toolbox talk to brief the team on its findings before starting.
