Occupational Hygiene Air Sampling Workshop

Toronto, Canada,
Date: May 4 - 6, 2011

Course Director Charles Pilger, CIH, ROH

WORKSHOP OBJECTIVES

Air contaminants in the workplace are an important source of potential worker exposure to chemical hazards. Reliable monitoring for these contaminants is an essential part of the health risk assessment process. To evaluate worker exposures to airborne contaminants, the hygienist must understand air sampling strategies and be skilled in air sampling techniques.

As part of its commitment to occupational health education and training, ALARA Industrial Hygiene Services is offering a three day course in practical air sampling techniques. This course will provide participants with the practical skills and theoretical knowledge to enable them to conduct reliable air monitoring surveys. Participants will gain experience with conventional air sampling equipment for personal exposure monitoring, and real-time air monitoring instruments. The course has been designed for professional occupational hygienists who feel the need to enhance their knowledge of air monitoring as well as recent entrants to the hygiene field who need to know how to conduct air sampling for chemical contaminants in their workplaces. This will be the 35th time this workshop has been presented.

Course enrollment is limited to 15 participants to maximize hands on experience with sampling equipment, and participant interaction. A brochure and registration form are available here.
