Occupational Hygiene

Occupational Hygiene looks at the evaluation and control / prevention of workplace hazards that may result in injury or illness, and the impact on the well-being of workers. RPS’ Occupational Hygienists help organisations to understand the risks to both employees and employers, and can assist in the management of programmes to comply with Health and Safety legislation.

Programmes of monitoring, coupled with occupational hygiene best practice advice, are provided to assist in the understanding and mitigation of exposure risk; typically risks are associated with chemical, biological, physical, ergonomic and psychosocial stressors.

Key service areas include:

Occupational Exposure Monitoring

Workplace Noise Monitoring

Environmental Noise Assessment

COSHH Assessment and Review

Hand Arm Vibration (HAV) and Whole Body Vibration (WBV) Assessments

Local Exhaust Ventilation (LEV) Examination and Testing

Indoor Air Quality Assessment

Key Services

Occupational Exposure Monitoring

Occupational exposure monitoring is used by organisations to comply with the COSHH regulations where employers must ensure that the monitoring of airborne contaminants is undertaken and to maintain adequate controls.

Measurement data is provided in order to evaluate exposure and assess the control measures, and monitoring is undertaken in accordance with recognised Health & Safety Executive methodology or internationally recognised standards.


The Control of Noise at Work Regulations require employers to ensure the risk from exposure to noise is either eliminated at source or controlled to as low a level as possible. Additionally there is a requirement for employers to provide suitable hearing protective equipment (HPE) for those exposed to noise, and health surveillance for employees who are at risk.

A workplace noise assessment includes the measurement of noise through personal dosimetry to identify those exposed at or above the defined exposure values. Measurements are also undertaken to identify machinery and areas that give rise to noise which is likely to contribute to operative exposure. Evaluation of existing controls and assessment of HPE are also undertaken and advice on implementation of controls to mitigate exposure provided.


A COSHH assessment concentrates on the hazards and risks from harmful substances in the workplace. The assessment will gather information about the substances and working practices, and give an evaluation of the risks to health and the necessary measures to comply with the COSHH regulations. The onsite assessment will also evaluate the processes that emit dust, fume, vapour, mist or gas and consider the level of skin contact or alternative routes of exposure.

Vibration (HAV/WBV)

The Control of Vibration at Work Regulations require employers to ensure the risk from exposure to vibration is eliminated at source or reduced to as low a level as possible. Employers are also required to provide suitable information, instruction and training to those affected by both hand-held tools and vehicles that may impart vibration.

Our Occupational Hygienists evaluate the magnitude for both hand-arm vibration and whole body vibration and can determine permissible contact time for operatives prior to reaching or exceeding evaluation criteria, and allow for appropriate controls to be implemented in order to mitigate exposure.

Local Exhaust Ventilation (LEV)

Local Exhaust Ventilation (LEV) is used in workplaces as an engineering control to capture process contaminants at source and mitigate operative inhalation exposure. Employers have a duty to ensure control systems are fit for purpose and assessed at specific intervals.

Testing of LEV systems is undertaken by BOHS P601 qualified RPS Occupational Hygienists in conjunction with the requirements of the COSHH Regulations, and comprises three stages:

Thorough visual inspection of all parts of the system to verify the condition and cleanliness of the system.

Thorough technical performance examination against criteria set out in HSG258 through physical measurement.

Assessment of the system to determine the effectiveness of control and whether it is fit for purpose. 

Face Fit Testing

RPS provides a wide range of adaptable, on-site Respiratory Protection Equipment (RPE) services designed to assist organisations in complying with legislation and improve the health and safety of employees. Respiratory protection is covered in a multitude of legislation including the COSHH regulations and the Health and Safety at Work Act, and RPS services include:

RPE risk assessments in line with HS(G)53

RPE selection, donning and maintenance training

Qualitative and quantitative face fit testing delivered by a qualified Fit2Fit technician

Portacount® Hire

Breathing air testing

These services can be combined with other RPS services such as occupational hygiene monitoring or occupational health screening to provide a time efficient and cost effective solution.
