Occupational Hygiene Services
Occupational hygiene services assess and monitor worker exposure to health hazards — including airborne dust, fumes, fibres, noise, and chemical agents — in industrial, construction, commercial, and laboratory environments. These assessments are required where substances hazardous to health are used or generated, where Workplace Exposure Limits may be approached or exceeded, or where employers need to demonstrate COSHH compliance. Monitoring involves personal and static air sampling using calibrated equipment, with laboratory analysis carried out by UKAS-accredited facilities. Results are reported against current Workplace Exposure Limits and accompanied by recommendations for control measures, RPE selection, and ongoing monitoring where risks are identified.
What Are Occupational Hygiene Services?
Occupational hygiene is the discipline of identifying and managing workplace health risks caused by chemical, biological, physical, and ergonomic hazards. Services include exposure monitoring, risk assessment, control strategy development, and compliance reporting. The objective is to quantify the level of worker exposure to hazardous agents — such as dust, fumes, fibres, noise, and vibration — and compare those levels against Workplace Exposure Limits (WELs) set by the Health and Safety Executive. The results inform practical decisions about control measures, RPE selection, health surveillance requirements, and ongoing monitoring programmes.
When Are Occupational Hygiene Assessments Needed?
- When workers are exposed to dust, fumes, vapours, or chemical agents
- To fulfil COSHH assessment and monitoring requirements
- When noise or vibration levels may exceed action values
- Before and during refurbishment or demolition involving hazardous materials
- Following changes to processes, materials, or work methods
- When health surveillance identifies concerns requiring investigation
- To validate that control measures (LEV, RPE) are performing effectively
- When enforcement notices or regulatory enquiries require evidence

How We Deliver Occupational Hygiene Services
Scoping and Planning
We review your operations, processes, and any existing exposure data or COSHH assessments to define the monitoring strategy and scope of work.
On-Site Monitoring
Our occupational hygienists attend site to conduct exposure monitoring using calibrated sampling equipment. Personal and static samples are collected as appropriate to the hazard.
Laboratory Analysis
Samples are submitted to UKAS-accredited laboratories for analysis. Results are compared against current Workplace Exposure Limits.
Reporting and Recommendations
You receive a comprehensive report with measured exposure levels, compliance status, and prioritised recommendations for control improvements where needed.
Frequently Asked Questions
What types of exposure monitoring do you carry out?
We carry out personal and static air monitoring for respirable dust, inhalable dust, asbestos fibres, silica, welding fume, wood dust, volatile organic compounds, and other substances with Workplace Exposure Limits. We also provide noise assessments and can advise on hand-arm vibration exposure.
Do you provide COSHH assessments?
Yes. We can carry out COSHH assessments as standalone documents or as part of a broader occupational hygiene programme. Assessments identify the hazardous substances present, evaluate the risk, and recommend appropriate controls.
What qualifications do your occupational hygienists hold?
Our occupational hygiene team includes professionals holding BOHS qualifications including the Certificate and Diploma of Operational Competence in Occupational Hygiene. We also hold BOHS P402 for asbestos surveying and sampling.
How long does a workplace exposure assessment take?
Duration depends on the number of exposure groups, processes, and substances involved. A single-substance assessment for a small team may require one day on site. Larger or multi-process assessments may span several days. We provide time and cost estimates during the scoping stage.
Can you help us set up an ongoing monitoring programme?
Yes. For employers with recurring exposure risks, we design structured monitoring programmes with defined frequencies, exposure groups, and review intervals. This supports compliance and helps identify trends over time.
Do you provide RPE face-fit testing?
Yes. We provide quantitative and qualitative RPE face-fit testing in accordance with INDG479. This can be delivered as part of an occupational hygiene assessment or as a standalone service.
