The webinar will focus on:
a) Understand ventilation within the context of the hierarchy of controls.
b) An update on international standards / guidance and good practices used a reference to upgrade ventilation.
c) A process flow to determine where improved ventilation is required and the order for different types of ventilation control including both dilution and filtration of air.
d) How to determine what respiratory protective equipment (RPE) is required, using a risk-based approach, and how ventilation and RPE requirements are integrated following CSA 94.4

e) An introduction on the OHCOW ventilation calculator, with an overview on how to apply this tool, as a precursor to the hands-on workshop during a follow-up webinar on Friday, February 11, 2022, from 1 pm - 3 pm.
f) The second half of the training session will involve "breakout sessions", where participants are asked to "share real world examples" in how they have tried to improve the ventilation in their workplace, problems encountered and raise questions that can be addressed during these sessions.
