Our dedicated team of site analysts conduct accredited air monitoring primarily related to asbestos removal and remediation works. Our services include:
Our air monitoring services are designed with the client in mind. We understand that scientific test reports are not always the easiest things to understand. Our reports are designed to be simple to read and provide clear and unambiguous results and advice.
Our analysts operate from a fleet of mobile laboratories so they can be completely self-sufficient on site.
Four stage clearance testing
Four stage clearance testing is a legal requirement following licensed asbestos removal works. As the name suggests, the four stage clearance is a process with four stages for signing off an area before it can be returned to normal occupation. The four stages are:
- Preliminary check of site condition and job completeness
- Thorough visual inspection of removal enclosure
- Clearance air monitoring
- Final assessment of work area and sign off
A four-stage clearance must always be conducted by an independent UKAS accredited analytical Company.
Reassurance, leak and background asbestos air monitoring
The above are routine types of asbestos air monitoring that can be conducted to establish background ambient fibre levels, check areas adjacent to asbestos removal/remediation works, and general compliance monitoring.
A visual inspection is carried out as part of the four-stage clearance process. A visual inspection could also be undertaken to check on the completeness and effectiveness of non-licensed asbestos removal works, encapsulation of ACMs and following clearing of ground contamination.
Personal compliance asbestos air monitoring
Personal asbestos air monitoring is undertaken to check the exposure levels of people working with asbestos. Usually this will be operatives working on licensed asbestos removal projects but can also include for example:
- Ground workers working on contaminated sites
- People working in an industry that involves use the Asbestos (increasingly rare these days)
- Someone undertaking surveys or sampling for asbestos
- Excavator drivers working on contaminated ground
Smoke testing is undertaken to test the integrity of asbestos removal enclosures prior to the removal works starting. The asbestos removal enclosure is filled with smoke from a smoke generator. The analyst then checks all seals, surfaces and adjacent areas for signs of smoke leaking from the enclosure. Once happy that all leaks have been remedied, the analyst will sign off the enclosure as fit for purpose and asbestos removal works can commence.
Perimeter Asbestos Air Monitoring
Perimeter monitoring is conducted to check airborne fibre levels around demolition, construction and remediation sites. The Analyst will assess the site conditions, prevailing wind direction and nature of works to devise a monitoring strategy that will provide suitable peace of mind to operatives working on the site, passers-by and occupants of neighbouring sites and buildings.
Many of the asbestos surveys we undertake each year are carried out on behalf of property developers. This type of client generally falls into three distinct categories. Those looking to buy a property but wanting an asbestos survey first. Those that have already bought a property and now need an asbestos survey to start demolition…
Is it Licensed, NNLW or NLW? First you need to decide whether the works are classified as licensed, notifiable non-licensed works (NNLW) or non-licensed works (NLW). To put it simply, work on high risk or friable asbestos containing materials are likely to need a licensed asbestos removal contractor (LARC). Work on the lower risk or…
The factors that will determine the cost of an asbestos survey are many. In this article I’m going to try to set out the main variables to give you a better understanding of what you need. What you should expect to receive and how much it will all cost. If you don’t want to read…
So who should undertake your asbestos testing and sampling? How do you check that the person/company doing the asbestos testing is competent and will offer independent advice? After all, it’s not a substance you want to be messing around with. My quick search for ‘asbestos testing’ on the Google has thrown up 17 results on…
Buying a new home is a stressful time. It’s the most expensive thing you’ve ever bought. You have already handed over a sizeable chunk of cash to your solicitor, mortgage broker etc. You’re all set to move. You’ve planned your new kitchen, set a provisional date for house warming barbecue. What can go wrong? Then…
