Occupational Health

We have a team of Environmental Contamination engineers, with specialists in methamphetamine testing, dust management, noise management,  toxic mould investigations and silica dust management.

Meth Testing

We provide an independent service for testing and validation, separate from remediation works to offer our clients a thorough service with the client’s needs at the forefront.

We have strict health and safety protocols around staff and client safety, and offer sampling regimes that ensures the client gets the best information to determine the levels of contamination (if any) and inform any remediation recommendations.

Our partnership with a fully accredited methamphetamine test laboratory ensures they can process methamphetamine samples within 24 hours of the samples being received.  Allowing for courier time and lab results analysis we can provide result reports back to clients generally within 48 hours of the sampling being taken.

Noise Testing

Noise is a significant hazard in many New Zealand workplaces. Noise not only causes hearing loss but also causes stress-related health problems and increase the risk of accidents.

Noise-induced hearing loss is caused by being exposed to too much noise for too long and can create problems in daily life for people affected. There is no cure for noise induced hearing loss.

We will identify noise sources, assess the general and personal exposure limits and compare it to legislation and give advice on what class hearing protection to use and what control measures could be implemented.

Indoor Air Quality Testing

Indoor air quality needs to be comfortable and safe. This environment is an important concern for employers and good indoor air quality can increase workers’ concentration and productivity.

  • Volatile Organic Compounds (VOCs) are toxic gases that are emitted from certain solids or liquids.  VOCs can be found in common household products including paints, varnishes, paint removers, cleaning products, building materials, glues, adhesives and office equipment such as printers and copiers. Breathing in VOCs can cause both short and long-term effects such as headaches, dizziness, and nausea and in severe cases organ failure and many types of cancer.
  • High levels of Carbon dioxide may cause people to grow drowsy, get headaches, or to function at lower activity levels.
  • By depriving the brain of oxygen, high levels of carbon monoxide can lead to nausea.
  • Poor air quality could include Carbon monoxide, Formaldehyde, Benzene, Particulates and Gasses.
  • Humidity levels Relative humidity is the percentage of water vapour in the air at a specific temperature; compared to the amount of water vapour the air is capable of holding at that temperature. Low humidity can causes symptoms such as static electricity, dry skin and lips, scratchy throats and noses, and itching. It increases your discomfort levels and increases susceptibility to colds and respiratory illness. High humidity can cause musty odour, clammy feel to the air and can disrupt the body’s ability to cool itself. High humidity can make it easier for molds to reproduce, damaging whatever they grow upon and pose a threat to allergy and asthma sufferers.

If you suspect you have an indoor air quality problem, we can test the quality of air and compare it to regulations which could potentially indicate whether there is a problem.

Chemical and Dust Exposure

A chemical or dust survey is performed to collect representative exposure data, to check the effectiveness of control measures, or a change in the manufacturing process.

Levels of exposures to dust and chemical hazards are listed in the WorkSafe NZ Workplace Exposure Standards (WES).  We can perform a workplace assessment  assess what type and level of chemicals or dust your workers are exposed to which will assist you keeping your workers safe and healthy as well as assist with hazard control and implementation of control measures.

Workers in the industry are exposed to Chemicals, Dusts as well as Solvents on a daily basis.

Routes by which chemicals can enter the body are by Inhalation (breathing), Skin (or eye) contact, Swallowing (ingestion or eating) and Injection. Effects of chemical exposure could depend on the type and dose of contamination.

Dusts entering the respiratory tract may be divided into ‘respirable’ and ‘non- respirable’ fractions.

Respirable dust is composed of the very fine dust which is able to reach the lower bronchioles and alveolar regions of the lung such as crystalline silica, Man Made Mineral Fibres (MMMF) and Diesel Particulates. Non Respirable dusts include particulates up to 100 microns and could include heavy metal components such as mercury and lead.

Health issues associated with solvent exposure include liver and kidney damage, toxicity to the nervous system, respiratory impairment, cancer, dermatitis and reproductive damage.

Mould

Mould is an allergen that can be harmful to anyone who is exposed to it for long periods of time.  Mould typically grows in damp, warm and dark conditions both indoors and outdoors.

Some symptoms from allergies to mould could include:

  • Nasal and sinus congestion, runny nose.
  • Respiratory problems, such as wheezing and difficulty breathing, chest tightness.
  • Cough.
  • Throat irritation.
  • Sneezing / sneezing fits.

The way to solve a mould problem is to get rid of the moisture and dampness.

We could measure the extent of the mould problem by taking air samples then getting levels and type of mould from an accredited laboratory.
