Entry into Confined Spaces with Escape & Full Working Breathing Apparatus


High-risk classified confined spaces are team entry operations into spaces such as tunnels, shafts, gas works, and places of restricted access that pose a significant threat to safety. They can require full working breathing apparatus to carry out works or rescue. But what type? Does the team know how and when to use it? And what about emergency procedures? This knowledge can save lives.

This Citrus certification delivers the necessary skills, knowledge, and understanding of confined spaces to work safely in a high-risk area using self-contained breathing apparatus. It is specifically aimed at those working in and around high-risk confined space operations requiring entry and particularly dangerous.

Course Outline

Made up of a majority of practical exercises, supplemented by classroom-based tutorials, delegates will cover legislative knowledge and awareness while taking part in realistic simulations of confined space entry and exit to fully understand how procedures and protocols work and why they are in place.

The course reflects national standards and industry best practices and is fully compliant  in line with regulations. In addition, choose to work with Citrus, and we can tailor courses to fit your specific training needs, with the added flexibility provided by our custom-built training facilities and customer-first approach to how we work.

Our occupationally and technically-experienced trainers will coach delegates in this two-day course, completing the session with a practical observation and short answer question paper. They must pass both elements to qualify for the certificate.

Course Programme

This training is essential to educate workers operating in high-risk confined spaces to execute work in such areas safely. Delegates will review legal requirements, ensure safety compliance, understand procedures and appropriate documentation and classifications.

The course will take delegates through;

  • The dangers associated with confined space working   
  • How to risk-assess a confined space   
  • How to classify a confined space using national classification guidelines   
  • Different types of breathing apparatus and when they are appropriate
  • How to carry out pre-entry and pre-wearer checks on equipment and why
  • Correct and safe use of atmospheric monitoring equipment    
  • The necessary manning levels - taking into account their risk-assessment and safety procedures  for a high-risk space
  • The reasoning for periodic examinations of equipment   
  • The emergency procedures when working in a high-risk confined space
  • Performing an entry using self-contained breathing apparatus   
On Completion

At the end of the training, successful delegates will be able to:

  • Understand confined space legislation and how classifications are given (NC, low/medium/high-risk)
  • Produce safe systems of work for entry into confined spaces, including point of works risk assessment
  • Recognise diseases and understand the necessary personal hygiene requirements associated with confined spaces
  • Identify types and administer the  safe use of atmospheric monitoring equipment   
  • Know how to use personal protective equipment, including  harnesses and access equipment   
  • Identify and know how to use respiratory protective equipment - particular focus on escape and self-contained breathing apparatus
  • React competently and confidently in an emergency
  • Manage atmospheric hazards - gas, chemicals, harmful substances, oxygen and more
  • Administer emergency procedures for safe working practices
Who Should Attend?

This Citrus Certification is for people who want to work in high-risk confined space activities aged 16 or over and are medically fit to participate.

Course Duration

This comprehensive two-day course trains delegates to safely and responsibly work in high-risk confined space operations and the challenges, processes and protocols involved.

Things You Need to Know

This Citrus Certifed course has practical elements, so delegates must be medically fit to train. Therefore, they must inform their trainer if they have any serious health issues, physical problems, special considerations or are taking any medication, which may create difficulties in conducting elements of this training course. 

For this Confined Space course, delegates must be clean-shaven. Glasses cannot be worn, instead opt for contact lenses or approved mask inserts. Face-fit testing must have been undertaken before sitting the course.

Popular FAQ's

Yes - delegates need to have a good understanding of the English language to take the course.

You need to attend an accredited course set to Water UK Standards. We offer the City & Guilds qualifications set to Water UK Standards and permit work on water and utility sites.

Yes, we can bring our mobile confined space unit to site; you need to provide a suitable classroom for the theory parts of the course and adequate parking for the mobile unit. Also, we may be able to use a non-live confined space with a permit to work and risk assessment if you have one. Please contact our team to speak to one of our advisors for more information.

Certificates and cards can vary depending on the awarding body. Generally, these can take six-eight weeks.

No, Citrus Training provides all equipment for the courses. However, you will need to bring your own standard PPE ie hard hat, safety footwear and hi-vis.

There is a mix of theory and practical elements on the confined space courses, with an assessment for both segments.

Three years.

There is no grace period set, but once your certificate has expired, you need to do the whole course again. Unfortunately, we do not offer refresher courses.

Course type will depend on the confined space you work in and the equipment you use. For example, Top person / Entry Controller is for candidates who DO NOT enter a confined space but man from the to p, and Entry is for people who physically enter a form of confined space. Please contact our friendly team to speak to one of our advisors for more information.

Yes, you need to be clean-shaven for this course. Nothing is allowed to interfere with the mask and the seals.

Yes, you can as long as you pay into the CITB levy. As an ATO, we will do this automatically for you if we have your CITB number.
