ALARA began as a Canadian company offering consulting services in occupational and environmental health and safety to the private and public sector.  The company was started in 1987 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. In addition to workplace consulting, we also offered a number of professional development courses for practicing OH professionals. We continued our consulting practice until 2018 when we retired from full time field consulting.

Our clients had been  organizations covering all occupational sectors where workers might be exposed to chemical, physical, biological, or ergonomic hazards. Our contribution was to recognize and evaluate the severity of these hazards and to propose appropriate control strategies.

In late 2017 we decided to retire from conducting workplace investigations and in 2018 we stopped offering our classroom training courses. Since then we have tried shifting our focus to providing practical educational material in health and safety online. Our intent is to act as a source of online resources in occupational hygiene, particularly for those looking for practical solutions to problems in workplace health and safety.

One 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 contact us for advice. We have made many presentations to workers and management on health hazards, their evaluation and control and developed worker training programs for our clients. In addition we have offered intensive, 1-3 day professional development courses for occupational hygienists and other allied professionals.

This site will present updates of our resource materials, making 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 should have a strong background in the physical sciences as well as a knowledge of biological sciences including human physiology and toxicology.

Our past clients have represented a broad spectrum of work environments, with potential worker exposures to many different hazards. Industry sectors we serviced include the following:

If you have responsibility for health and safety, there is a good chance that sooner or later, you will find material on this site that is of interest to you.
