Sample questions
01What is the legal definition of a confined space under UK regulations?
- AAny room that has no permanent mechanical ventilation or air conditioning system serving the working area at any time
- BAny enclosed space where there is a reasonably foreseeable risk of serious injury from hazardous substances or conditions
- CAny space that is fully sealed below ground level, since underground voids are the only places where dangerous gases gather
- DAny work area under two metres in height in which a person is unable to stand fully upright while carrying out the task
Why: Under the Confined Spaces Regulations 1997, a confined space is defined as any place which is substantially (though not always entirely) enclosed, and where serious injury can occur from hazardous substances or conditions within the space, or nearby. It is the risk, not just the size, that defines a confined space.
02Which of the following is a key characteristic of a confined space?
- AIt must be smaller than the minimum dimensions specified in the regulations
- BIt must be situated underground or below the surrounding ground level
- CIt must be completely sealed with no openings to the outside atmosphere
- DIt must be substantially enclosed and have a reasonably foreseeable risk of serious injury
Why: A confined space has two key characteristics: it is substantially (though not always entirely) enclosed, and there is a reasonably foreseeable risk of serious injury from hazardous substances or conditions. A space does not need to be underground, sealed, or unlit to be classified as confined.
03Which of the following is an example of a confined space?
- AAn office with permanent mechanical ventilation and two exits
- BA storage tank that previously held chemicals
- CA workshop fitted with extract ventilation and multiple windows
- DAn open-top skip in a well-ventilated yard
Why: A storage tank that previously held chemicals is a classic example of a confined space. It is substantially enclosed, has limited access and egress, and there is a foreseeable risk of serious injury from residual hazardous substances, oxygen depletion, or a build-up of flammable vapours.
