This Section tells you about activities of the AIHA Manitoba Presidents, the latest progress by AIHA Manitoba Standing Committees and other events.

Adjusting Occupational Exposure Limits
October 6, 2009

Canada Inns Polo Park
 8 AM to 4 PM
 $50/person

Continental breakfast and buffet lunch provided.
 Maximum 30 attendees.

First five to sign up and agree bring a laptop for the workshop case studies get in free.

Who should attend? Managers, Supervisors, Workplace Safety and Health Committee members, Safety Professionals, Union Representatives.

In 2006, the Workplace Safety and Health Regulation was adopted. One of the things it emphasized was that the workplace exposure limits adopted in Manitoba (TLVs) are to be used as intended by the TLV Committee. This means adjusting the TLVs to take into account differences in conditions of the workplace and the workforce. Failure to take these conditions into account can lead to overexposed workers even when the exposure limits are met. Examples are shown below. 

EFFECT

CONDITION

POSSIBLE EFFECT

Worker Health

Lead exposure with a minor kidney impairment

19% reduction in TLV to maintain equivalent effect

Other Exposures

5 ppm environmental carbon monoxide level

10% reduction in TLV to maintain equivalent total exposure

Worker Sensitivity

Sensitization to MDI

70% reduction in TLV to protect workers

Unusual Work Schedule

Exposed to carbon monoxide for 4 days / week, 10 hrs / day

20% to 50% reduction in TLV depending on model used to maintain equivalent exposure

Physical Exertion

Working with carbon tetrachloride at a moderate work load

50% reduction in TLV to maintain equivalent exposure

Multiple Routes of Exposure

A worker’s hands are contaminated with ethyl benzene for 30 minutes / day

The workers exposure is 4.8 times the TLV

 

 

 

 

 

 

 

 

 

 Making these essential adjustments can be difficult for someone unfamiliar with the practice of occupational hygiene. To assist workplaces and safety committees to meet their responsibilities under Manitoba legislation, the Manitoba Workers Compensation Board has funded the development of a guideline for non-occupational hygienists.

WORKSHOP

To help introduce the guideline to Manitoba Workplaces the Manitoba Local Section of the American Industrial Hygiene Association is planning a workshop on how to comply with this part of the Manitoba Regulation 217/2006.

Teaching method is a combination of Power Point lecture, class discussions, and two person teams completing problems in the appropriate chapters of the workbook. The minimum class size is 10 and the maximum class size is 24 participants.

Students should bring their own calculator.

The instructor for the course is Gary Johnson. He is an industrial ventilation system engineer with over 25 years of experience with system design, maintenance, and technical training. He is a frequent presenter of Industrial Hygiene Professional Development Courses and for engineering conferences and webinars.
