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.
