Occupational Hygiene Consultancy
Occupational hygiene consultancy focused on employee health.
Consultancy-led support to identify, assess and control workplace health risks around air quality, noise, hazardous substances and exposure controls.


Joined-up advice that reduces disruption.
Where appropriate, SML can combine LEV testing with air monitoring and COSHH assessment reviews, and can also complete noise assessments at the same time to improve oversight and reduce disruption.
What We Cover
The main occupational hygiene service areas.
Air sampling
Personal and static air sampling is used to understand how airborne contaminants such as dusts, solvents and isocyanates are affecting the workplace in practice, not just in theory.
The aim is to build a clearer evidence base around exposure levels, task risk and control performance so decisions on further action are proportionate and defensible.
LEV examination and testing
Thorough examination and interval testing checks whether extraction systems are performing as intended and continuing to protect employees under COSHH requirements.
This helps businesses move beyond relying on the presence of LEV alone, by understanding where maintenance, adjustment or further review is needed to keep exposure controls effective.
- Review of control performance against the way the system is actually being used.
- Clear findings on any remedial action or follow-up priorities.
Noise assessment
Noise assessments measure employee exposure in line with the Control of Noise at Work Regulations 2005 and help clarify where action values, hearing protection or control improvements need closer attention.
The focus is on turning measured results into practical control decisions so managers can understand what matters most and how to reduce long-term hearing risk in live working environments.
Dust exposure measurements
Static or personal monitoring to MDHS 14/4 guidance helps quantify particulate exposure and gives a more reliable picture of how dusty activities are affecting employees across the shift.
This is particularly useful where processes, housekeeping standards or ventilation performance make it difficult to judge risk confidently from observation alone.
COSHH assessments
COSHH assessments review how hazardous substances are used, where exposure can occur and whether the controls already in place are suitable for the task, process and people involved.
Recommendations are then shaped around practical improvement, helping businesses strengthen handling, storage, ventilation, PPE and supervision where required.
- Useful where new substances, tasks or process changes alter the exposure profile.
- Supports clearer control decisions instead of relying on generic substance information alone.
Combined advisory support
LEV testing, air monitoring, COSHH assessment reviews and noise assessments can be planned together so exposure risks are considered as part of one joined-up programme rather than in isolation.
This improves value, reduces disruption on site and gives leadership teams a more coherent view of where health risks sit and which actions should be prioritised first.

Occupational Hygiene FAQs
Answers to common questions about exposure monitoring, LEV testing, COSHH reviews and noise assessment support.
SML provides consultancy support to help organisations identify, assess and control workplace health risks, including air sampling, LEV examination and testing, noise assessment, dust exposure measurements and COSHH assessments.
Yes. Where appropriate, SML can combine LEV testing with air monitoring and COSHH assessment reviews, and can also complete noise assessments at the same time.
Yes. Monitoring can include personal and static sampling depending on the process, exposure route and what evidence is needed to understand how well controls are working.
Yes. Where site activities allow it, SML can plan a combined programme so multiple exposure risks are assessed efficiently during the same visit or project phase.
Clients receive clear results, an explanation of what those results mean, and practical recommendations on priorities, controls and any further action needed.
