Welcome to ALARA!

ALARA Industrial Hygiene Services Ltd. is a Canadian firm of occupational hygiene professionals offering a comprehensive range of consulting services in occupational and environmental health and safety. Services offered include occupational air sampling, noise exposure evaluation, indoor air quality assessments, investigations of mold and other microbial agents, workplace risk assessments, worker training and professional development courses for occupational health professionals.


Our goal is to work with our clients to protect the health of their workers, the natural environment, and the community from those hazards arising from the workplace. ALARA’s occupational hygienists are dedicated to the recognition and evaluation of workplace hazards and will recommend any appropriate control procedures that will improve worker well-being and productivity.

Why ALARA? We are often asked what ALARA means. Actually it is an acronym for “As Low As Reasonably Achievable”. This is a philosophy first espoused by health physicists regarding the reduction of exposures to ionizing radiation. Occupational hygienists later appropriated the ALARA concept for application to all workplace hazards, chemical, physical and biological. The ALARA principle recognizes that although it may not be possible to reduce exposures to zero, efforts should be made to reduce exposures as much as possible. We chose the name ALARA because it reflects our belief that workers should be protected from all hazards that could, over a working lifetime, lead to disease or impairment. At the same time we recognize that reduction of these exposures to zero may not be practical, due to the presence of non-occupational exposures to many hazardous agents.
