Your Workplace Occupational Hygiene

Occupational Hygiene

Occupational hygiene is the science of identifying, evaluating, reporting and controlling workplace conditions that may cause your workers’ injury or illness.

Environmental monitoring equipment is used to detect the extent of worker exposure and recommend suitable engineering or work practice controls, to eliminate, isolate or minimise potential health risks and hazards.

Occupational Hygiene services include:

Asbestos Sampling

Asbestos removal in a safe manner is crucial to the continued health of your team. Asbestos can be found in many New Zealand workplaces. Unfortunately asbestos, when inhaled as respirable fibres over a period of time, can result in asbestosis, lung cancer and mesothelioma (cancer of the lung lining).

Chemical and Dust Exposure

Has a workplace assessment been made to assess what type and level of chemicals or dust your team are exposed to? Do you know what the WorkSafe Workplace Exposure Standards are for your worksite and has your teams exposure to the potential chemical or dust been assessed and monitored on a frequent basis? All important questions your organisations is required to answer in the area of exposure.

Fungi and Bacteria Monitoring

Are any of your team exposed to Fungi and/or Bacteria while at work? Fungi, bacteria, their spores and endotoxins (cell wall components) may be present in the workplace environment without you being aware of it. Recognised conditions such as Farmers Lung (extrinsic allergic alveolitis) and Psittacosis (Pigeon Fancier’s Lung) can result from exposure to bacteria and fungi in mouldy hay and bird excrement.

Heat Stress

New Zealand has a very changeable climate, and while most of us are not exposed to excessively hot or cold conditions during our working lives, there are some occupations and situations in which extreme environments are encountered. Heat stress measurements are especially important for staff who work in very hot, cold, or humid enclosed workplaces, or where a significant radiant heat source exists. Managing heat stress can improve workflow and decrease illness in your employees.

Indoor Air Quality

How safe is your indoor air quality? Providing a comfortable, safe and healthy indoor environment is an increasingly important concern for employers. Good indoor air quality can increase workers’ concentration and productivity.


Eye strain caused by poor or inappropriate lighting can lead to very real discomfort, inaccuracy and loss of productivity. Adjust the lighting, reflection and glare in your workplace so they are appropriate to your employees’ tasks is significant.

Workplace Noise

Noise induced hearing loss has been identified as one of the major occupational diseases affecting New Zealand workers. Noise induced hearing loss is notifiable to WorkSafe as a serious injury.

TriEx’s workplace noise assessments include the identification of noise sources, the assessment of employee noise exposures, advice on administrative and PPE controls and recommendations for engineering and longer-term controls.
