Under the Confined Spaces Regulations 1997, Regulation 5, when must emergency arrangements be in place?

Regulation 5 of the Confined Spaces Regulations 1997 is clear that suitable and sufficient arrangements for the rescue of persons in the event of an emergency must be in place BEFORE any person enters or works in a confined space. This applies to all confined space entries, regardless of the perceived level of risk. Emergency arrangements must be proportionate to the identified risks and must be practised.

Only when the risk assessment identifies a high likelihood of an incident

Before any person enters or works in a confined space

Within 24 hours of the entry commencing

Only when working in confined spaces classified as 'high risk'

What is 'non-entry rescue' in the context of confined space emergency procedures?

Non-entry rescue is the preferred primary rescue method. The entrant wears a full-body harness with an attached retrieval line connected to a mechanical retrieval device (winch) mounted on a tripod or davit at the entry point. If the entrant becomes incapacitated, the top person or rescue team can winch them out without anyone entering the space. This eliminates the risk of rescuers becoming additional casualties.

A rescue method where two rescuers enter the space together to extract the casualty

A rescue method where the casualty is left in place until the emergency services arrive

A rescue method where the casualty is retrieved from the confined space without the rescuer entering, typically using a retrieval line and winch system

A rescue method where the space is flooded with water to float the casualty to the surface

What is the primary advantage of non-entry rescue over entry rescue?

The primary advantage of non-entry rescue is that it eliminates the risk of the rescuer becoming an additional casualty. Historically, a significant proportion of confined space fatalities are would-be rescuers who enter a hazardous atmosphere unprepared. Non-entry rescue allows the casualty to be retrieved mechanically while the rescuer remains in safe air outside the space. It should always be the preferred method where the geometry of the space permits it.

It is faster to set up because no equipment is needed at the entry point

It allows more rescuers to enter the space at the same time

It removes the need for atmospheric monitoring during the rescue

It eliminates the risk of the rescuer becoming a casualty in the hazardous atmosphere
