The HSE wants to highlight ways in which operatives can come to grief in confined spaces. Other than lack of oxygen, workers can be affected by a number of hazards: by flammable substances and oxygen enrichment; toxic gases, fumes or vapours; or drowning and asphyxiation in both wet and dry substances.
The HSE advises employers to 'get to grips' with the Confined Spaces Regulations 1997 if they have to send operatives into these areas. It states that entry into confined space must be avoided if at all possible. But, if work must be carried out, then all, not one or some, of the following steps must be taken:
- a risk assessment must be carried out and a safe system of work drawn up;
- entry into the space must be limited to those who are competent and thoroughly trained;
- the status of the atmosphere in the confined space must be ascertained before anyone is allowed into it;
- ventilation must be provided, as should suitable rescue arrangements.
