Dusts & Chemical HazardsDusts & Chemical Hazards

Dust and Chemical Hazard Assessments

Exposure to airborne contaminants such as dusts and chemicals in the workplace can lead to serious health risks, including respiratory issues, skin irritation, and long-term conditions such as cancer. D.A.L specializes in identifying hazardous workplace substances and providing exposure assessments to mitigate these risks.

Our Dust & Chemical Hazard Assessment Services Include:

  • Inhalable and Respirable Dusts: Including but not limited to; heavy metals (mercury, lead), crystalline silica (RCS), wood dusts and Man-Made Mineral Fibres (MMMF).
  • Diesel Particulate Matter (Diesel Fume): Assessment of exposure to harmful diesel exhaust.
  • Welding and Soldering Fumes: Including heavy metal analysis (e.g., chromium, nickel, zinc) and fume exposure.
  • Organic Compounds: Including VOCs, formaldehyde, isocyanates, and solvents.
  • Inorganic Chemical Exposure: Alkaline and acid gases, chemical fumes.

Physical Hazard Assessments

In addition to noise, exposure to physical hazards such as vibration and thermal environments in the workplace can be a neglected cause of harm. D.A.L consultants specialize in identifying hazardous workplace environments and undertake exposure assessments to mitigate these risks.

Our Physical Hazard Assessment Services Include:

  • Noise: As outlined above.
  • Thermal Exposure: Heat and cold exposure assessments for extreme workplace conditions.
  • Vibration Assessments: Including both hand-arm and whole-body vibration.

Our team conducts thorough assessments in accordance with both New Zealand Workplace Exposure Standards and international guidelines, providing actionable recommendations to minimize dust, chemical and physical hazard exposure risks.


Indoor Air Quality (IAQ) Testing & Assessments

Poor indoor air quality (IAQ) can impact both employee health and productivity. D.A.L offers professional IAQ testing and assessments to evaluate the quality of air in your workplace. We help identify pollutants such as asbestos, microbials and fungal contaminants, and volatile organic compounds (VOCs), which can cause a range of health issues from headaches to serious conditions such as asthma and cancer.

Common Indoor Air Quality Issues:

  • Sick Building Syndrome (SBS): When more than 20% of building occupants report symptoms related to indoor air, such as headaches, fatigue, or eye irritation.
  • Building-Related Illness (BRI): Medically diagnosable conditions caused by exposure to contaminants in the building.
  • Multiple Chemical Sensitivity (MCS): Sensitivity to chemicals, which may cause symptoms even at low concentrations.
  • Microbial and Fungal Growth: The presence of airborne microbes and fungi, such as mould and bacteria, which can cause respiratory issues, allergic reactions and infections.

We provide comprehensive IAQ assessments, testing for a range of pollutants and based on our findings, we provide tailored recommendations to improve air quality, safeguard employee health, and enhance workplace productivity.
