Occupational Hygiene

What is Occupational Hygiene?


Occupational hygiene is the anticipation, recognition, evaluation, and control of environmental factors or stressors arising in or from the workplace, which may cause sickness, impaired health and well-being, or significant discomfort among workers. Such stressors can include chemical, physical, biological, and ergonomic hazards. The goal of occupational hygiene is to protect the health and well-being of workers and the community by identifying and controlling potential hazards in the workplace.


Workplace Exposure Monitoring


Safe and Sound Solutions can conduct workplace exposure monitoring and exposure assessments throughout New Zealand. We employ a number of real-time assessment techniques that can allow preliminary assessment against the New Zealand workplace exposure standards without the initial cost of a full exposure survey. This allows controls to be improved prior to workers personal exposure assessment. The latest workplace exposure standards can be found on Worksafe NZ website. We also offer assistance with Personal protective and respiratory protective equipment including respirator fit testing.


Safe and Sound Solutions


Out team of Occupational Hygienists have extensive experience and knowledge not only in the field of Occupational Hygiene, but also in a variety of supplementary disciplines such as chemistry and environmental science, among others. No matter your industry or the size of your company, we provide expert occupational hygiene services, followed by a comprehensive report. As leaders in the industry, we are qualified to assist you on your journey to a safer, more productive workspace.

Dust Monitoring


  • Real time and personal exposure monitoring (respirable and inhalable) services for dust and particulate.
  • Real time monitoring allows us to assess compliance and the need for personal monitoring without the initial cost of a full survey. This is achieved using the latest technology from the UK and, coupled with our ventilation assessments can effectively assess your existing controls.
  • Some of the materials we monitor are wood dust, coal dust, synthetic man-made fibres (fibreglass) and silica.

VOC Monitoring


  • Real time semi-volatile and volatile organic compound (VOC) monitoring
  • Latest equipment allows for ppb (part per billion) level detection
  • VOCs are generated by a variety of processes including spray painting, gluing, solvents, petrol, aromatics and other hydrocarbons.

Gas and Vapour Monitoring


  • Range of monitoring technology that allows for the detection of most gases and vapours.
  • Commonly being carbon monoxide, carbon dioxide, oxygen, hydrogen sulphide, perchloroethylene , benzene and toluene.
  • We can detect over 300 compounds so please enquire if your substances are not listed.

Welding Fume Monitoring


  • Welding and metal work can produce a range of particulates and metal vapoursnthat are dangerous to health.
  • Real time monitoring of fume for the assessment of local extraction ventilation (LEV) systems
  • Personal exposure monitoring for comparison against the WorkSafe NZ Workplace Exposure Standards.
  • Typically this monitoring can include total inhalable particulates and subsequent trace metal analysis.

Noise Monitoring


  • Occupational and environmental noise assessments.
  • Plant assessments
  • Personal exposure including dosimetry,
  • Maximum daily exposures
  • Hearing protection class assessment
  • Noise maps
  • Engineering control recommendations. 

Ventilation Assessment


  • Assessment of ventilation systems including spray booth, local extraction and total building ventilation.
  • This can include the measurement of capture zones, vapour diffusion patterns and hazardous material clearance times.
