What is Confined Space training?

A confined space is an area that workers can physically enter to carry out works with restricted or limited entrance and exit points and time allowance to get in and out.

In addition, the space will pose considerable risks to anyone working in it. Lack of oxygen, exposure to poisonous fumes and gasses, fire and explosions, free-flowing liquids and solids (such as grain), dust and residues, extreme temperatures and limited ease of escape are all very real hazards to contend with. They are known as ‘specified risks’ within the industry.

There is also the fact that confined spaces can be created as a job progresses. Works that may start off in a simple configuration can become confined due to increasing building works, debris, or accidentally. So it is critical that people working in confined spaces know what they are dealing with and can adapt quickly.

Confined space training enables employees who work in or near these spaces to stay safe and for businesses to be legally compliant. Companies by law have a duty of care to provide appropriate training for their employees in their given working conditions, and confined spaces present dangerous challenges for untrained employees.

Nearly all industry sectors will have confined spaces consisting of various scenarios and hazards that employees will need to navigate to carry out their work. These spaces include;

  • Silos
  • Tanks
  • Storage bins
  • Pits
  • Shafts
  • Vaults
  • Sewers and Drains
  • Tunnels
  • Ductwork
  • Pipework
  • Unventilated or poorly ventilated rooms
Which course should I take?

At Citrus, we offer a comprehensive range of courses for Confined Space Training. Our accredited confined space courses are Citrus Certified or City & Guild Certified, depending on your requirements, with 14 courses available from Awareness to Level 4.

We also offer CABWI-accredited Confined Space Courses as dedicated courses. Get in touch if you would like to receive more information.

Whether you need low, medium and high-risk certification, entry-level training, rescue courses or high-level combined qualifications, we have you covered. Our accredited courses take participants through extensive learning and instructional processes to ensure they know and understand the risks and procedures to conduct within all aspects of their confined space course. Throughout the programmes, our trainers handle rescue techniques, escape, full working and airline breathing apparatus, basic first aid, CPR and resuscitation, through to rescue team coaching and extensive competency-based training.;

Citrus Certified
We have six fully accredited awards on offer covering confined space awareness, permit issuing, responsible persons and the specific variations of breathing apparatus as required for different spaces, including airline. When booking, note that some courses do not qualify workers to enter a confined space and are knowledge-based for supervisory purposes.

City & Guilds Certified
Covering the same topics and requirements, the 6160 awards from City and Guilds replace the 6150 in December 2021. The updated qualification content ranges from Level 2 to 4 and is based on the National Occupational Standards developed by Energy & Utility Skills for the industry.

City & Guilds UK standards are explicitly written for the water industry. For some employers in the sector, these awards are the minimum standard they’ll accept for employees and contractors. This is important to note to ensure delegates take the correct course as required.

Whether Citrus or City & Guilds, we can deliver most of our courses in our custom-built mobile unit, meaning we can come to you nationwide for speed and ease, or you can visit us at one of our dedicated training sites.
