Air monitoring is a requirement prior to re-occupation of a building following asbestos encapsulation or removal. Monitor Env Ltd holds accreditation for fibre counting and 4-stage clearances and is independently audited by UKAS to ISO/IEC 17025 to sample and count fibres to HSG248 ‘The Analysts’ Guide’ (previusly MDHS 39/4)
Monitor Env Ltd has a team of qualified analysts who are all equipped to produce on-site results to the highest standard. We offer a wide range of monitoring services:
Clearance inspections
Removal work is followed by an independent inspection by our UKAS accredited laboratory to ensure standards of decontamination are sufficient to comply with statutory requirements.
The areas are not re-commissioned for use until the air / fibre level in the vicinity had been proven to be below the lowest limit of detection.
Background monitoring
Conducted in order to ensure acceptable fibre levels upon commencement and during installation of control measures.
Smoke testing and commissioning
Conducted to ensure that the asbestos enclosures are air-tight in order to minimise exposure to third parties. Following a successful test, the enclosure is commissioned for use by the asbestos consultant and contractor supervisor.
Leak monitoring
Conducted to verify the integrity of the enclosure and air management systems and that the environment is suitable for occupation in the immediate vicinity of the enclosures. Such is important to ensure the safety of employees, contractors and members of the public.
Personal exposure monitoring
Conducted in order to ensure that safe systems of work designed to reduce exposure and dust generation are effective and that the respiratory protective equipment provided is of a sufficiently high protection factor for the task.
Reassurance air monitoring
Conducted to provide the client with further confidence that all areas worked in have been left in a state suitable for reoccupation of employees and third parties.
