It is a legal requirement for a detailed Commissioning report to be carried out by a competent LEV Test Engineer following installation or changes to an existing system.
The report will include evidence of the effectiveness of control.
It is essential that testing is carried out by qualified staff covered
by professional indemnity insurance for inspection and certification
of LEV. P&J have PI Insurance as LEV design, commissioning and
LEV inspection specialists and our competence is independently
verified by UKAS accreditation for LEV Commissioning and inspection.
P&J LEV reports are comprehensive and comply in every respect
with the COSHH approved code of practice L5 and HSG258.
A Commissioning report is carried out after installation. It provides both qualitative and quantitative data following detailed performance checks and measurements that set the operating parameters at which control of the hazardous substances was assessed as effective. This assessment of control effectiveness and comparison with the agreed exposure benchmarks enables you to ensure that the system always remains at the intended operating performance and continues to protect your employees from exposure to the hazardous substance.
Our commissioning report covers both the LEV system equipment/hardware and the operators' work practices.
A commissioning report should include:
-
a statement whether or not the four key statutory obligations under COSHH are achieved:
-
the system is effectively controlling the hazardous substance
-
the system is in good condition
-
the system is clean
-
the system is being used correctly
-
-
diagrams and a description of the LEV
-
photographs
-
details of the LEV performance specification and whether or not this is being achieved
-
pressures and air velocities at stated test points
-
calculations made
-
written descriptions of commissioning, the tests made and the outcome
-
air sampling results
-
filter efficiences
-
concentration of the contaminant in the cleaned air if returned to the workplace
-
a description of how operators were using the LEV and how they should by using the LEV so that it works effectively
-
a prioritised action plan detailing any improvements or best practice recommendations.
