COSHH LEV testing & servicing, ventilation balancing and commissioning

Here, we’ll discuss the intricacies of COSHH LEV testing & servicing, ventilation balancing and commissioning


In the UK the Control of Substances Hazardous to Health (COSHH) Regulations have focused the attention of industry on the need to protect the workforce from exposure to hazardous substances in the workplace, COSHH and LEV Testing are essential in achieving this.

COSHH requirements

No work that exposes anyone to substances hazardous to health, shall be carried out until an assessment has been made and appropriate control measures implemented.

COSHH sets out essential measures that employers – and employees – have to take. 

COSHH is also a useful tool of good management, which can bring many benefits including saving you money and help employees reach a better understanding of health and safety.

“Control measure” means a measure taken to reduce exposure to a substance hazardous to health, including the provision of systems of work and supervision, the cleaning of workplaces, premises, plant and equipment, the provision and use of engineering controls and personal protective equipment.

Every employer who provides any control measure to meet the requirements of Regulation 7 shall ensure that:

In the case of plant and equipment, including engineering controls and personal protective equipment, it is maintained in an efficient state, in efficient working order, in good repair and in a clean condition. In the case of the provision of systems of work, supervision and of any other measures, it is reviewed at suitable intervals and revised if necessary.

How R&B Industrial Ltd. can help

R&B Industrial Ltd. provide the following services, to enable compliance with the relevant COSHH regulations and ensure your LEV plant and filtration processes are operating at maximum efficiencies:

Local Exhaust Ventilation (LEV) initial appraisals, assessments and testing to determine adequacy of control measures.

Periodic thorough examination and testing via maintenance and service contracts if required.

These can be carried out once every 14, 6 or 3 monthly depending upon process, hazard and substance.

R&B Industrial’s test engineers are also trained in service / maintenance of LEV systems so it may be cost effective to have the system serviced at the same time as carrying out your COSHH LEV Testing. Competitive servicing contracts are provided for a wide range of plant including;

  • Electrostatic precipitators
  • Wet and dry scrubbers including venturi, packed bed, cyclonic / impingement
  • Wet and dry paint booths
  • Processes involving highly hazardous products such as isocyanates, cyanide, beryllium, chromates
  • Performance criteria and analysis
  • LEV Design and design appraisal services
  • Specialist expertise for explosive substances DSEAR

We also carry out minor remedial works, whilst on-site if competent, safe and covered by risk assessments. This can often save a return visit, saving our customers money.

Advice on design of Continuous On-line Monitoring systems can also be provided if applicable ie for return air systems back to the workplace. 

As well as COSHH and LEV Testing, general ventilation system balancing and commissioning works are also undertaken, to confirm correct air changes/air flows as per specification/design data. We also provide reports with test data and system logbook if applicable.
