Hazardous Area Cleaning
Hazardous areas on site still require the same level of cleaning and housekeeping as standard areas, but they come with much higher risks. Our hazardous area cleaning service helps you meet your health and safety obligations by providing trained technicians who are qualified to clean in high-risk environments without compromising safety or compliance.
What is Hazardous Area Cleaning?
Hazardous Area Cleaning involves the safe and thorough cleaning of environments where the risk to health and safety is significantly elevated. These areas may contain biological, chemical, electrical or atmospheric hazards that require specialist handling.
Examples of high-risk areas include:
- High pathogen risk areas, such as spaces with dead carcasses, faeces or mould
- Confined spaces, such as vessels, tanks, ducting, basements and ceilings
- Explosive atmospheres, such as milk powder stores and factories
- Toxic atmospheres from gas, fumes or chemicals, such as stormwater sumps
- High voltage areas, such as 1100KVA yards or salt-coated insulators
- Chemical storage areas, for example – where the liquid is a burn hazard for eyes, skin and clothes, or the fumes are a respiratory hazard
- Cooling towers
Is Hazardous Area Cleaning right for you?
Common applications in commercial and industrial settings include:
- Sites with areas classified as hazardous
- Businesses needing qualified cleaning in confined spaces or high-voltage zones

What are the benefits of Hazardous Area Cleaning?

Other service recommendations:
We recommend this service is accompanied by a Safety Watcher. A safety watcher will already be included in any hazardous area cleaning work we carry out to protect our team on site. However if you're undertaking hazardous area cleaning yourself and need a trained safety watcher to oversee the job, we can provide one to support your staff.
Our process:
- We complete a detailed site assessment to understand hazards, risks and confirm that the service requested is best suited to your needs.
- Before photos of the area are taken to provide in the condition report on completion of the job.
- The work is undertaken by our team, ensuring all necessary precautions are taken and the correct PPE is worn.
- After photos of the area are taken and the final report of the work completed is written up by our technicians.
- Our report is uploaded to your customer portal for review and future audits.
