ALARA is a Canadian company that has offered consulting services in occupational and environmental health and safety to the private and public sector since 1987. The company was started by a husband and wife team, of Certified Industrial Hygienists, with a strong interest in applying their scientific training to the prevention of occupational illness and injury.

Our clients have been organizations and institutions where workers may be exposed to chemical, physical, biological, or ergonomic hazards. Our contribution has been to recognize and evaluate the severity of these hazards and to propose appropriate control strategies when necessary.

In late 2017 we decided to retire from conducting workplace investigations and in 2018 we decided to stop offering our classroom courses. We decided instead to investigate shifting our focus to providing educational materials and acting as a source of online resources for occupational hygienists  and others interested in workplace health and safety. Over the next few months this web site will undergo a number of changes reflecting this change in emphasis.

One important service we have always provided is to act as an educational resource for both employees and health and safety management personnel. We have encouraged our clients to call us for advice on solving health and safety problems in their workplaces. We have made many presentations to workers and management on health hazards, their evaluation and control. We have developed a number of worker training programs for our clients as well as our intensive, 1-3 day professional development courses for occupational hygienists and other occupational and environmental health and safety people. The changes we are making in this site will essentially update and repackage some of these materials to present them on the site to make them more widely available to the occupational hygiene community.

Industrial / Occupational Hygiene

The designation industrial hygiene is used primarily in North America. Throughout most of the world, our profession is known as occupational hygiene and its practitioners are called occupational hygienists.

The role of an occupational/industrial hygienist is to anticipate, recognize, evaluate, and control hazards in the workplace that may be harmful to employees, the community, or the natural environment. This requires an understanding of industrial processes, and the health and safety hazards associated with these processes. Occupational hygiene is an interdisciplinary field; a competent hygienist must have a strong background in the physical sciences as well as a knowledge of biological sciences including human physiology and toxicology.

By identifying and evaluating health hazards, and recommending control procedures, we have assisted clients in their efforts to maintain and improve the quality of working life and productivity of their workers and to protect the community in which they live.

ALARA’s clients have represented a broad spectrum of work environments with the potential for worker exposures to chemical, physical, biological or ergonomic hazards. Industry sectors we serviced include the following:
