During the voyage
- The ship’s heeling angle and rolling period should be checked, in a seaway, on a regular basis.
- Wedges, hammers and portable pump, if provided should be stored in an easily accessible place; and
- The Master or a responsible officer should ensure that it is safe to enter an enclosed cargo space by:
- Ensuring that the space has been thoroughly ventilated by natural or mechanical means;
- Testing the atmosphere of the space at different levels for oxygen deficiency and harmful vapour where suitable instruments are available; and
- Requiring self-contained breathing apparatus to be worn by all persons entering the space where there is any doubt as to the adequacy of ventilation or testing before entry.
