The typical characteristics of an unsafe space is as follows :
- Space – Space that is not designed for continuous occupancy
- Accumulation – a capacity to Accumulate a hazardous atmosphere
- Ventilation – severely limited natural Ventilation
- Exits – Exits that are not readily accessible
- how to identify potentially hazardous enclosed spaces which might not normally be considered as such (with some examples);
- the need to carry personal O2/multimeters and how to use them;
- the need to carry out training and drills for entry as well as emergency drills:
- the importance of using EEBD’s for individual escape purposes only;
- information on a new MNTB training course for enclosed space entry.
- crew members are encouraged to make their own assessments and not rely entirely on signage or permanent designations. They should also be assured that they will not be criticised for erring on the side of caution.
COSWOP 17 requires that a competent person, who should be trained on enclosed space hazard recognition, evaluation, measurement, control and elimination, must make an assessment of the space where there is a risk that the atmosphere is unsafe breathing apparatus must be worn
Emergency Evacuation Breathing Devices (EEBD’s) are designed for personal use for escape only andshould never be used for rescue or space entry. Crew members must be trained in its use and limitations.
