Short courses

Short courses will be offered by top experts in their fields, immediately preceding the conference. These in-depth courses will be essential for professionals who want to stay abreast of the most recent developments and techniques in their areas of expertise. The short courses are available on a first-come, first-served basis.  The organizer reserve the right to cancel a short course if the number of participants does not meet the minimum number required.


2-day short course - Saturday and Sunday, October 19-20

Half-day short course - Sunday, October 20 from 1PM to 5PM

Assessment and Control of Diesel Particulate Matter in Mining

Instructors: Robert Stoyanoff, CChem CIH, Senior Industrial Hygienist, Golder Associates’ North American Mine Environment Division & Courtney Gendron, MPH, Occupational Hygienist, Golder’s Mine Safety & Industrial Hygiene Group.

This course is designed to assist mining OH&S, ventilation and equipment maintenance professionals, supervisors and technicians in the management of worker exposure to diesel exhaust particulate matter (DPM) in the mine environment. The course focus is on the composition and toxicity of DPM, historical and current legislative requirements and exposure limits, past and current best practices in exposure assessment/air sampling techniques, DPM emission control technologies and recent advances in real time monitoring instrumentation.

The focus of the course is on current best practices in the risk assessment and control of exposure to diesel particulate emissions in the mine environment. This course is intended for mining professionals and technicians in the fields of health and safety, industrial hygiene, ventilation and equipment maintenance.

Tickets: $50 registered student delegates | $125 regular registration
