What is a Confined Space?

In the UK, the primary legislative articles that regulate working within confined space environments are ‘The Confined Space Regulations 1997’. Within Statutory Instrument No.1713, a confined space is defined as:

“confined space” means any place, including any chamber, tank, vat, silo, pit, trench, pipe, sewer, flue, well or other similar space in which, by virtue of its enclosed nature, there arises a reasonably foreseeable specified risk…

Although certain confined spaces can be clearly apparent, the classification of a confined space can be subject to change based on both fixed and variable factors. When undertaking an assessment of a confined space, the principal objective is to determine all probable specified risks, of which:

“specified risk” means a risk of—

(a) serious injury to any person at work arising from a fire or explosion;

(b) without prejudice to paragraph (a)—

(i) the loss of consciousness of any person at work arising from an increase in body temperature;

(ii) the loss of consciousness or asphyxiation of any person at work arising from gas, fume, vapour or the lack of oxygen;

(c) the drowning of any person at work arising from an increase in the level of a liquid; or

(d) the asphyxiation of any person at work arising from a free flowing solid or the inability to reach a respirable environment due to entrapment by a free flowing solid;

Confined Space Assessment, Access & Entry

Where access into a confined space is required to undertake work, initially, a full confined space assessment needs to be undertaken by a trained and competent person. This is to identify and quantify the associated specified risks.

Following this assessment, an appropriate plan of work including full methodology, a comprehensive risk assessment, and the required control and mitigation measures can be developed to form a viable and safe ‘system of work’.

Confined Space: Safe System of Work

A confined space ‘safe system of work’ will account for, but not be limited to, the risk factors associated with, fire and explosion, the effects of temperature, atmospheric conditions, the presence and fluctuation of liquids, and asphyxiation or entrapment by free-flowing solid materials.

Control measures for eliminating, monitoring, or mitigating the determined risk factors also need to include variations that may occur as a result of the works process, such as where the use of chemicals are required, or where burning and welding activities are involved.

Confined Space Emergency Planning & Rescue

Emergency preparedness is a vital aspect of planning works within a confined space environment. Dependent on the type and level of risks identified, characteristics of the confined space, and the nature of the works being undertaken, a designated confined space rescue team may be necessary to readily action a pre-planned emergency procedure.
