In the fourth incident, a deck hand slipped and fell down a ladder leading from the deck to the paint store. He was found at the foot of the ladder in pain and unable to move, subsequently he required a medevac.

Incident 5 – Fall on the same level: LTI on offshore vessel

Lessons learnt

Our Member summarised that irrespective of the height, the potential consequence of a fall can be extremely severe and the above cases are clear evidence of this. A fall from a height is entirely avoidable if procedures are followed, risk assessments and tool box talks are conducted also suitable and sufficient mitigation is in place.

Our Member recommended the following:

  • Implement the conditions of the Permit to Work, consider operations which may be undertaken concurrently with others.

  • Ensure personnel are suitably qualified and experienced.

  • Provide adequate supervision.

  • Use appropriate working at height equipment and tooling.

  • Conduct a toolbox talk.

  • If in doubt ‘stop the job’ and re-assess.

Members’ attention is also drawn to the wide range of IMCA safety promotional materials, which will be of use in mitigating risks of this sort, including:
