The Hygienists

Marg&Chuck-HygienistsMarguerite Pilger,
Senior Occupational Hygienist and Project Manager.
Marguerite has a BSc in chemistry and a BA in psychology (Waterloo) and an MEng in industrial hygiene (Toronto). She has conducted occupational hygiene field investigations, indoor air quality assessments, designed and maintained hazardous materials databases and presented courses, workshops and in-plant seminars in occupational health and safety.

Charles (Chuck) Pilger,
Senior Occupational Hygienist and Occupational Hygiene Chemist.
Chuck has an MSc in organic chemistry (Waterloo) and an MEng in industrial hygiene (Toronto). Prior to starting ALARA he taught university courses in occupational health and safety and environmental analysis for over 15 years. He also directed the activities of three occupational hygiene teaching and analytical laboratories and continued to collaborate on research projects in occupational hygiene and environmental health after leaving full time university teaching. With Marguerite, he has continued to present a range of industry specific in-plant worker training programs and a number of professional development workshops in occupational hygiene for practitioners in the field.

For the last 6 years we have been involved with the work of Workplace Health Without Borders, a not-for-profit organization promoting occupational health in the developing world.  This involvement convinced us that we could make an important contribution if we reinvented ALARA as a not-for-profit organization, where we could make our collective expertise available to OHS practitioners in the developing world. 

Ethical Practice

We have always adhered to and promoted the ethical, professional practice of Occupational Hygiene. Although we have retired from professional field hygiene practice, and have voluntarily surrendered our CIH and ROH credentials as a result of retirement, we still consider ourselves bound by the codes of ethics of the Canadian Registration Board of Occupational Hygienists and the American Board of Industrial Hygiene. Our primary interest remains assisting in the protection of the health and safety of workers everywhere.
