Asbestos Air Monitoring & Clearance testing.

Air examining and examination is amazingly paramount in deciding such variables as the potential danger of presentation to any asbestos holding materials. It is in this manner key that such estimations are completed skilfully, utilizing the appropriate testing techniques and gear.

We are focused on giving a solid and reliable asbestos site examining and testing service and for guaranteeing that inspecting and testing are completed effectively and dependably. Key to this commitment is guaranteeing our experts being sufficiently prepared with specific training to perform the examining and testing.

We provide suitable laboratory facilities and that the laboratory equipment we utilize is suitable for the particular tests required.

An air inspecting method will be prepared, assessed and qualified before any asbestos repair work is undertaken, in order to guarantee that all parts of the work are secured.

This process commonly incorporates inspecting, leak testing, site clearance certification and confirmation for re-occupation, reassurance sampling, personal sampling, and certification and reporting.

Background Sampling

Specialists who carry out asbestos air inspecting and analysis will utilize various examining applications relying upon the customer’s detailed expectations and scope of works. One such system is Background Sampling. Preceding the commencement of any movement that may prompt asbestos filaments becoming airborne, and as an outcome potentially risky, ‘background  testing and sampling’ must be conducted, keeping in mind the end goal to establish a baseline ambient level of asbestos.

Leak (Enclosure Check) Testing

Testing outside a fenced in area and in adjacent areas during the evacuation/removal process to guarantee that fibre containment is adequate and effective.

Site evaluation for Re-occupation

Following asbestos evacuation, the premises must be evaluated to assess if they are completely clean and fit for reoccupation (or, as suitable, demolition).

The clearance certificate procedure is an imperative part in asbestos removal work. The issue of an endorsement of reoccupation by a fair and capable and approved organization gives the vital assurance and security to the resulting building occupiers or clients.

The multi-stage affirmation methodology is intended to permit the examination and evaluation to be performed in an organized, methodical and consistent way.

It is the obligation of the authorized builder undertaking the asbestos evacuation work to thoroughly and industriously clean up the work area. At the point when the authorized builder is satisfied that the zone is clean and ready for future utilization, the area is surveyed by an expert of an independent association which is licensed by UKAS as conforming to ISO 17025. The certifying analyst’s function is to give an independent verification check that the work area is clean and suitable for re-occupation.

There are four stages to the site accreditation and certification for re-occupation appraisal methodology completed by the expert/analysis:

stage 1:           Preliminary check of site condition and work completeness;

stage 2:           An intensive visual assessment inside the enclosures/work zone;

stage 3:           Asbestos air measurement and monitoring;

stage 4:           Final evaluation post-enclosure/work area removal and dismantling of plant and equipment.

Stage 3 air examining happens once an intensive visual investigation has been completed and the expert/analyst is satisfied that all the asbestos in the POW has been evacuated, and there is no unmistakable trash or layers of settled dust. All air measurements established by the investigator conform to the ISO 17025 standard. The value calculated from each single specimen taken during the site clearance testing is measured against clearance indicator value of 0.010 strands for every cubic centimeter. Only when this evaluation of the work environment is passed as satisfactory is a certificate of re-occupation issued. The certificate is issued to the builder and, as suitable, to the client where the latter has instructed the expert/analyst.

Asbestos staying in enclosed areas (retained by design) ought to be marked that it is asbestos and that it is to remain. These asbestos items that remain can then be checked by the expert against the work plan and recorded on the certificate of re-occupation. The building owner/occupier should then make sure the location of the asbestos is incorporated in their asbestos administration plan.

Reassurance Sampling

This sort of checking may be needed in specific circumstances, for example, when a walled in area has been destroyed on completion of asbestos evacuation/removal, to affirm that the residual asbestos airborne fibre clusters are less than 0.01 strands for every cubic centimetre of air inspected.

Personal Sampling

Personal Sampling is to be completed when it is important to evaluate the exposure level of an individual doing his/her work. In this case examining is completed on asbestos evacuation/removal staff working in fenced in areas, ensuring that satisfactory respiratory equipment is worn (alluded to as a RPE test). In addition, inspecting to check compliance with the Control Limit under the Control of Asbestos Regulations 2012 is yet another situation where particular testing is required.
