CONFINED SPACE
& PLANT CLEANING

Safe, compliant and tightly controlled cleaning of tanks, silos, vessels and complex industrial plant. Delivered UK-wide.

TECHNICAL & HAZARDOUS CLEANING

Confined space and plant cleaning presents severe risks that demand rigorous protocols. Atmospheric hazards—including toxic gases, low oxygen levels, and combustible dust—require specialised monitoring and extraction systems before any personnel enter the site.

Restricted access points and complex internal layouts mean standard methods often fall short. Our teams work under strict safe systems of work, with continuous atmospheric monitoring and ATEX-rated equipment wherever the risk assessment requires it.

We understand that industrial maintenance happens within tight operational windows. Our crews coordinate directly with your H&S and plant managers to carry out deep cleaning and hazardous material removal during scheduled shutdowns, keeping downtime to a minimum.

WHERE WE WORK

From North West manufacturing sites to national infrastructure, our teams carry out confined space and plant cleaning across the UK. We mobilise trained operatives and specialist equipment wherever your site is located. Our guide to confined space and industrial plant cleaning covers the atmospheric monitoring and safety protocols behind every project in more depth.

TECHNICAL FAQ

HOW DO YOU HANDLE ATMOSPHERIC MONITORING IN CONFINED SPACES?

Continuous atmospheric monitoring is set up before entry and maintained throughout. Calibrated multi-gas detectors monitor oxygen, flammable gases (LEL), hydrogen sulphide (H2S) and carbon monoxide (CO), and evacuation is triggered immediately if alarm levels are reached.

ARE RESCUE PERSONNEL INCLUDED IN YOUR CONFINED SPACE ENTRY TEAMS?

Yes. Emergency rescue arrangements are planned and in place before every entry, as the Confined Spaces Regulations 1997 require. Rescue cover, with breathing apparatus and retrieval systems, is provided by trained personnel from our own team and our vetted specialist subcontractor partners, as the risk assessment determines.

WHAT SAFETY DOCUMENTATION AND PERMITS DO YOU PROVIDE BEFORE WORK BEGINS?

Before work begins, we issue RAMS, the safe system of work and confined space entry permits. Operative competency records and equipment calibration certificates are sent to your procurement and H&S teams before we mobilise from our North Wales base.

HOW DO YOU INTEGRATE WITH OUR FACILITY'S SHUTDOWN WINDOWS?

We understand that downtime is costly. Our project managers coordinate directly with your operations team for sites across the UK, fitting the work into your planned maintenance or emergency shutdown windows with out-of-hours and weekend working where needed.

WHAT CERTIFICATIONS DO YOUR OPERATIVES HOLD FOR HAZARDOUS ENVIRONMENTS?

Our confined space teams are trained for high-risk entry and rescue, with City & Guilds-qualified personnel from our own team and our vetted specialist subcontractor partners. As a company, ACS is a Constructionline Gold member, FSB member and Builder's Profile verified, and works to current UK safety legislation.
