Confined space entry needs skilled technicians and a clear understanding of the strict safety rules that govern this high-risk type of work.
One of the compliance regulations for confined space entry is the number of technicians required on any job. There is no straight answer to how many you need. It depends on the outcomes of a risk assessment and the work being carried out.
At Orb Rope Access, our technicians are fully trained and experienced in confined space entry. Although we’re best known for working at height, we also deliver a wide range of confined space services. Working closely with our clients, we make sure every project meets safety regulations, including having the right number of qualified operatives on site.
Before we explore this further, let’s take a look at the basics of confined space entry.
What is a confined space?
According to the Health and Safety Executive (HSE), a confined space “is one which is both enclosed or largely enclosed and has a reasonably foreseeable specified risk to workers of fire, explosion, loss of consciousness, asphyxiation or drowning”.
Cheery!
A confined space isn’t always small or cramped. It can also include large areas such as silos or tanks with hundreds of cubic metres of capacity.
What is confined space entry?
Confined space entry involves working in hazardous, enclosed environments. It requires industry experience and advanced training to follow strict safety procedures and protect workers.
Typical confined space entry work for Orb Rope Access includes silo or tunnel inspections, vessel cleaning, chemical plants, chimney inspections, dry risers (systems of pipework and valves that allow firefighters to access water on all floors), lift shafts and drainage.
How many people are required for a confined space entry?
The Confined Spaces Regulations 1997 stipulate that sufficient measures should be in place to manage emergencies or accidents during a confined space entry. This includes ensuring that there are enough trained operatives on site to complete the tasks and manage any risks.
A risk assessment must be carried out to decide how many people are needed for confined space entry. The number depends on the hazards and level of risk identified.
No one should ever enter a confined space alone. Regulations require at least two people: the entrant who performs the work, and a safety attendant, often called the “top man”
The top man’s role is crucial. They monitor the work, maintaining communication with the entrant and ensuring that all safety protocols are followed. They will also help to evacuate the entrant if necessary.
Alongside the entrant and top man, a supervisor is usually present often the employer or their representative. For higher-risk jobs, a dedicated rescue team should also be on site for an immediate response.
What influences the size of a confined space team?
- Size and layout of the confined space
Larger spaces may need more technicians to monitor all areas. - The tasks being completed
Tasks involving hazardous materials or welding often need extra safety personnel on site. - Potential emergencies
For particularly hazardous confined spaces, the rescue team may need to be larger to handle emergency evacuations. - How long the work will take
If the work is expected to take some time, during which confined space technicians need breaks, more personnel will be required both inside and outside the confined space.
