Summary The Ontario Workers Health & Safety Training Centre provides training on Indoor Air Quality. It’s valuable training for Joint Health and Safety Committee members to provide them on background to better understand how to go about gathering and analyzing information on indoor air in the workplace.

TL;DR: There is little to no evidence to show that coughing into your elbow prevents the spread of disease. Elbow-coughing has long struck me as a cop-out, but some posts on Twitter piqued my interest into digging around in the scientific literature.

If you feel that it's too hot or too cold in your office or classroom, you wouldn't expect your employer to say "Hey! You can't bring a thermometer into the classroom to measure temperature. You need expert training to read and set up that thermometer." Of course not. That's ridiculous. And the same goes for […]
The Workplace Incident Report form is meant to be filled out by your supervision when there is a health and safety incident, like when you slip and fall on ice at work. But it is also meant to be used when you _could_ have been injured -- for instance, by a falling object or a […]
The Titan submarine was officially declared destroyed yesterday, and everyone aboard it dead, not far from the wreck of the Titanic. In the days, months and years to come, scientists, engineers and journalists will comb through documents and videos to determine what went wrong and who should be blamed for the tragedy.

It's Fall 2022 and the masks are off. Well, officially, masking is a "personal choice". Leadership has dropped the COVID ball and is hoping that nobody is going to pick it up again. So what's left to do? Continue to mask, provide alternatives for everyone that don't require in-person gathering (classes, labs, meetings), get vaccinated […]
The following are a set of preliminary tests I did to determine relative speech sound performance while wearing a mask. I'm particularly interested in the context of mask-wearing in a classroom, but this could be helpful in many other workplaces. I tested a number of masks in my dining room. Audio levels were measured using […]
York University's EECS department has an Aranet4 CO2 sensor available for borrowing. Go to the ground floor of the Lassonde Engineering Building, and go to the sign-out desk in the PRISM computer lab at the south-west corner of the building (near the hallway that leads to the Steacie Library). The location is highlighted in light […]
[March 20, 2022 update] A version of the N95 motion was brought before YorkU Senate in January 2022 by Senator Patrick Phillips. It appears to have passed but has not led to subsidized distribution of N95s on campus. [Feb 2, 2022 update] The first motion (Recommendation for N95s) resulted in a recommendation email to all […]
I'm submitting the following four motions to my department's monthly meeting to see if we can set ourselves up for a safer return to campus. There are four motions: A recommendation for wearing N95 Funding for N95s A request for CO2 sensors A request for portable air purifiers (HEPA) Feel free to reuse and/or adapt, […]
