Industrial hygiene is a specialized profession that involves the recognition, evaluation, and control of hazards. As industrial hygienists, we are involved in the protection of the health of people in all aspects of their lives whether at work or in their communities. We identify, assess, and mitigate a wide range of hazards ranging from chemical, physical, biological and ergonomic stressors. Our goal at Aura is to make a difference in the world by improving the health of workers and the public through our efforts.


Exposure Assessment 

Exposure assessment is a branch of industrial hygiene and environmental science that involves evaluating contaminants or agents of interest, understanding the pathway to biological uptake, and estimating the absorbed amount which could lead to a health effect.  

Aura professionals have experience in conducting exposure assessments for a variety of hazards:

  • Chemical - volatile organic compounds, aldehydes, isocyanates, heavy metals, silica, asbestos and other fibres, etc.

  • Physical - noise, ionizing radiation, non-ionizing radiation including electric and magnetic fields (EMF) and radiofrequency fields (RF), ergonomic stressors

  • Biological - bacteria, fungi, viruses


Risk Management  

Management of risk can occur in many forms such as implementing exposure controls and providing information in an effective manner.

Aura professionals have experience in the following broad categories of risk management:

  • Exposure Control Planning:
    • Development of exposure control plans (ECP) for various exposure agents, such as asbestos, lead, crystalline silica, isocyanates, etc.
    • Development of safe work procedures (SWP) for various activities and tasks, such as disturbance of hazardous building materials, paint application, etc.
    • Evaluation and consultation on existing and potential control mitigation strategies
  • Risk Communication - Sharing of information with stakeholders on:
    • Levels of health or environmental risks
    • Significance of health or environmental risks
    • Actions for controlling


Indoor Air Quality

As the majority of us spends more than 70% of our time indoors, it is important that we breathe good quality indoor air. Poor construction or maintenance, using a building differently than planned, and even green initiatives that aim to conserve energy, can all contribute to poor indoor air quality.

As part of conducting indoor air quality investigations, we have extensive experience in:

  • Reviewing building plans and current and historical use of buildings

  • Engaging with building occupants to assess the breadth and extent of health issues

  • Assessing the adequacy of fresh air intake

  • Assessing moisture, mould and Legionella

  • Evaluating other potential sources of indoor air quality complaints (eg., new building material, outdoor sources)

  • Providing expert witness testimony

Hazardous Materials Management

Hazardous materials can exist in various forms, some of which may be present within buildings and facilities. Materials such as asbestos, heavy-metals (e.g., lead, mercury, and arsenic), polychlorinated biphenyls, crystalline silica and ozone-depleting substances require identification and management in order to ensure exposure hazards and health risks of building occupants and workers are properly mitigated.

Aura professionals have experience in management of hazardous materials for a variety of industries and purposes, such as:

  • Review and development of large-scale asbestos inventory programs

  • Development of asbestos management programs

  • Interpretation of relevant legislation applicable to industry and contractors

  •  Oversight of applicable hazardous materials aspects of construction projects
