Welcome to the ALARA web site!

ALARA Industrial Hygiene Services Ltd. was a Canadian occupational hygiene consulting company, that operated between 1987 and 2018.  It was founded by a husband and wife team of occupational hygienists, offering a comprehensive range of consulting services in occupational health and safety.

Our services included occupational air sampling, noise exposure evaluation, indoor air quality assessments, investigations of mould and other microbial agents, workplace risk assessments, worker training and professional development courses for occupational health professionals.

In 2018 we retired from active occupational hygiene consulting.  We continue to offer some consulting by telephone and email but no longer do in-plant investigations. We decided to shift the focus of ALARA toward providing educational material and online services on a not-for-profit basis.  By concentrating on an online model of information delivery we anticipate we will be able to offer cost effective informational assistance world-wide and in that way assist under-serviced areas of the world. This is frankly an experiment. We do not yet know whether there is interest in the information and material resources at our disposal, but we are reluctant to discard these resources when we know that there is a strong need for occupational hygiene in workplaces in Canada and around the world.


As consultants our goal has always been to work with our clients to protect the health of their workers, the natural environment, and the community from hazards arising from the workplace.

We hope to continue to do this through assisting other occupational hygiene and safety professionals around the world who may lack our resources for recognition and evaluation of workplace hazards and the recommendation of appropriate control procedures to improve worker well-being and productivity.

ALARA is an acronym for “As Low As Reasonably Achievable”, a philosophy first promoted by health physicists regarding the reduction of exposures to ionizing radiation. Occupational hygienists appropriated the concept for application to all workplace hazards, be they chemical, physical or biological. The ALARA principle recognizes that although it may not be possible to reduce exposures to zero, we should work to reduce workplace exposures as much as is possible, to limit harm and protect workers from those exposures that could lead to disease or impairment.
