LEV System Documentation

The HSE expect business owners to hold specific LEV system documentation to show evidence that you are making every effort to protect your employees from hazardous airborne substances.

LEV System Documentation

Every LEV system requires several documents that cover the process, the hazard, the operators and the system. These documents include, but may not be limited to:

  • Process risk assessment
  • LEV commissioning report
  • LEV thorough examination & test (TExT) report
  • LEV user manual
  • LEV logbook
  • Workplace air quality monitoring report
  • Training records
  • DSEAR risk assessment

Process risk assessment – employers must not carry out work which can expose any of their employees to any substance hazardous to health until a suitable and sufficient assessment of the risks to employees’ health created by that work has been carried out and relevant measures implemented. Your risk assessment must include details of the hazardous substance including workplace exposure limit where it exists.

LEV commissioning report – every LEV system should have a commissioning report from when the system was first installed (or after significant change). The commissioning report confirms that the system is performing as designed and that, in the commissioner’s professional opinion, the system delivers adequate control of exposure. It provides a reference against which to compare regular checks, maintenance and TExT. Where a commissioning report doesn’t exist, retrospective commissioning should take place in the form of an initial thorough examination & test (ITExT).

LEV TExT report – every LEV system must be thoroughly examined & tested at least once every 14 months and a suitable & sufficient report issued. This report must be kept by the employer for a minimum of 5 years.

Workplace air quality monitoring – exposure monitoring is covered under COSHH Regulation 10 and is a requirement for many workplaces. Control of exposure and compliance with EH40 is a legal requirement and in many cases the only way to prove this is by undertaking occupational exposure monitoring. This is particularly relevant to substances that have been deemed as a carcinogen, asthmagen or have a BMGV. 

LEV system logbook – all LEV systems require a logbook that contains schedules & forms to keep records of regular checking, maintenance & repair.

LEV user manual – just like the logbook, every system should have one! The user manual should cover how to use the system, how to maintain it, the spares available and a list of things that can go wrong. Where appropriate it should also contain a sufficiently detailed drawing and/or photograph.

Training records – under COSHH Regulation 7, employers must train employees how to use LEV systems including basic upkeep and how to identify a problem. A suitably detailed record of all training should be kept and updated as appropriate.

Dangerous substances and explosive atmosphere Regulations (DSEAR) 2002 require employers to control the risks to safety from fire, explosions, and substances corrosive to metals. Employers must identify what dangerous substances are in their workplace and take appropriate action. A DSEAR risk assessment classifies substances and helps decide what controls need to be put in place.

At Impact, we are experienced in providing documentation for such systems and are on hand to assist you. Call or email us today to ensure compliance and full protection.
