A confined space is a working environment that, due to its high level of risk, requires particular attention. Having a clear understanding of what is meant by confined spaces and being aware of the potential hazards faced by workers in such environments represent only the starting point for carrying out an effective risk assessment.

Within this section, the following topics will be addressed:

Definition of confined spaces

When referring to confined spaces, also known as “confined environments”, this includes all workplaces or working situations in which workers are required to operate in fully or partially enclosed areas, which are not designed for continuous human occupancy and are not intended to be used as such.

It can therefore be concluded that confined spaces present very high-risk conditions. Consequently, it is essential to carry out a proper risk assessment in order to anticipate and prevent the hazards associated with confined environments.

What are the risks in confined spaces?

The risks faced by workers operating in confined spaces are numerous and characterized by a high level of hazard. For this reason, those responsible for workplace safety are required to be fully aware of all risks and dangers associated with confined space work in order to ensure the highest possible level of occupational safety.

The most common risk factors encountered in confined spaces include:

With full awareness of these risks, it is possible to implement an effective risk assessment for confined space activities.

Risk assessment for confined spaces

According to Articles 17 and 28 of Legislative Decree 81/08, the risk assessment for confined spaces falls under the general obligation to assess all workplace risks. Carrying out a confined space risk assessment is not only mandatory, but also essential, as it protects workers and safeguards the organization against highly dangerous hazards such as asphyxiation and explosions.

In companies where confined space work is carried out, safety managers responsible for conducting an effective risk assessment are required to:

The confined space risk assessment also requires that the safety manager ensures that workers receive adequate training and instruction.
