PREVIEW: Confined spaces in construction low to medium risk

This preview is for ATO use. This is a practical course designed for operators who are likely to be working in low or medium risk environments.

This standard is available to ATOs to preview before it’s finally published. You should make sure your course matches these details. This standard will eventually supersede the existing standard in development. 

Until then, continue to publicise your courses against the existing title on the Construction Training Directory.


Minimum two days of 6 learning hours per day.


This is a practical course designed for operators who are likely to be working in low or medium risk environments.

The scope of this standard covers:

  • confined spaces: definition
  • risk assessment and training
  • safe systems of work
  • marking, fencing and permits to work
  • specialist personal protective equipment (PPE) including masks, harnesses, hoists, gas detectors, breathing apparatus
  • practice sessions
  • dangers and responses.

Occupational relevance

Training delivered against this standard would be relevant to the following occupational group(s):

  • operative and craft
  • supervision.

Candidate pre-requisites

There are no candidate pre-requisites as part of this standard.


As a minimum, course instructors must be able to demonstrate that, in relation to this standard, they have:

  • a train the trainer or instructional techniques course certificate
  • successfully completed training to this standard 
  • at least 2 years relevant industrial experience as a fitter
  • a verifiable CV.


Delivery may be in an on or off the job environment and will include opportunities to practice using specialist PPE in confined spaces.

All materials and equipment must be of a suitable quality and quantity for candidates to achieve learning outcomes, and must comply with relevant legislation.

The class size and candidate/instructor ratio must allow training to be delivered in a safe manner and enable candidates to achieve the learning outcomes.

The following delivery methods may not be used in the delivery of this standard:

  • e-learning
  • classroom
  • workshop.

This standard is considered to contain 51 per cent or more practical training.


For the successful completion of training, candidates must complete an end of course practical assessment or knowledge test that measures the learning outcomes and has a pass or fail criteria.

Quality assurance

Quality assurance against this standard will require initial approval of the training organisation and their content mapped to the standard. 

CITB will also conduct an approval intervention, either desk-based or centre visit, to ensure the training organisation can meet the requirements of the training standard. 

Approved training organisations (ATOs) will be required to present information on records of training and assessment upon request to CITB for desk based analysis. They will also be visited annually by the CITB quality assurance team.


Recommended refreshment: Health & Safety Executive (HSE), other relevant codes of practice or industry card scheme criteria recommend that the candidate completes a refresher of his/her training, (i.e. to ensure their knowledge and/or skills are up to date) every 3 years.

Approval date

To be confirmed

Review cycle

Either on request or in 3 years from approval date.

Learning outcomes

The candidate will be able to:

  • define a “confined space”
  • read and interrogate a formal risk assessment
  • describe what “safe systems of work” should be implemented in different confined space scenarios
  • explain the roles of marking, fencing and permits to work
  • enter and exit a medium risk confined space
  • use specialist PPE including masks, harnesses, hoists, gas detectors, breathing apparatus
  • identify the onset of danger and respond appropriately.
