SafeSpace Resources


We are developing a number of resources to help those who have committed to the SafeSpace Project to reduce seafarer injuries and fatalities in confined spaces. The material may be distributed freely but, except here specifically stated, copyright remains with Maritime Accident Casebook. No direct or indirect charge may be made to the seafarer for these materials nor may they sold or rented.

SafeSpace e-Book: Principle of Confined Space Safety

This free e-book has been in preparation for a year. Many of the cases featured on MAC has contributed lessons. It will be in two parts: Principles of Confined Space Safety and Case Studies. We would like to get opinions and suggestions from suitably qualified folk on how it could be improved before we finally release it publicly.

In a sense this is a living document: New information etc will be included as it becomes available.

If you’d like to help SafeSpace do email us at with the subject line ‘book’.

We’d also like to produce a hard copy version for distribution, for instance, to ships libraries. We’re open to sponsorship or advertising, or maybe you have some suggestions.

SafeSpace CBT

We’re just getting this part of the project moving: a free CBT for download/online Access. The idea is to get this into the hands of seafarers to give them a greater sense of ownership.

Online Case Studies

Most of these case studies have both audio and a transcript. As a suggestion, you could listen and/or read one every week or so and get discussions going among your fellow seafarers on confined spaces to help build awareness.

More “confined space that wasn’t” incidents

From Tom LittlePage:

Here is a short list of accidents which have happened during the past week or two. They might make decent current examples for those who do confined space training. Though easily predictable and preventable, these incidents are not uncommon.
