Understanding The Different Classifications Of Confined Spaces

Confined spaces are any partially or fully enclosed areas where one or more specified risks may be present. Because of these criteria, it can be challenging to define a confined space, so each area should be assessed individually for classification.

In this article, we’ll explore the main hazards of working in confined spaces, the various types of confined spaces, and the importance of confined space rescue training.

Dangers Of Working In Confined Spaces

According to the Health and Safety Executive (HSE), around 15 workers in the UK lose their lives each year in confined space accidents. Causes may include an inability to recognise confined spaces and their risks, inadequate safety systems, and failed rescue attempts.

In the United States, there are approximately 670 confined space deaths each year. Studies by the US National Institute for Occupational Safety and Health (NIOSH) found that nearly 60% of confined space fatalities involve rescuers attempting to aid and extract victims.

Confined Space Classification Types

Using the Confined Space Regulations 1997 and the Approved Code of Practice (ACOP) L101 will help determine if an area is a confined space. If it is classified as such, a comprehensive risk assessment must be conducted, and appropriate controls for the foreseeable risks must be implemented.

The risk assessment will classify the space as low, medium, or high risk. Here are some considerations for each category:

Low-Risk Confined Spaces:

Shallow entry points
Adequate natural or mechanical ventilation
Simple and unobstructed access
No likely risk of flooding

Medium-Risk Confined Spaces:

Possible restricted entrances
Realistic expectations of a specified risk being introduced
Planning allows for self-rescue or non-entry rescue
Use of escape breathing apparatus

High-Risk Confined Spaces:

Specified risks that cannot be controlled or eliminated
Potential hazards such as gas leaks, mechanical/electrical faults, or the danger of igniting the atmosphere
Possible access issues considering rescue capabilities
Rescue plan must reflect this level of risk
Use of self-contained breathing apparatus (SCBA)

Why Confined Space Rescue Training Is Crucial

Working in confined spaces exposes individuals to various potential dangers, some of which might cause serious injury or prove fatal.

Therefore, a rescue plan is required, along with competent confined space rescue training and assessment. This training provides individuals involved in rescue and recovery activities with the skills and competencies needed to assess risk and control hazards that may endanger the safe rescue of others.

Eurosafe’s training courses cover all areas of confined space operations, including providing all necessary equipment to ensure the safety of trained operatives. We have a mobile confined space training unit, which allows most confined space training courses to be conducted on-site.
