Day 4 #SDCC2022 from hall A to C

877 ppm CO2 at 4600s in exhibit hall #SDCC2022

870 ppm co2 at 5500s #SDCC2022 #covidsafetySDCC

953 ppm in 5A 5B hallway on second floor

644 ppm CO2 at the Gaming Zone

End of Day 4 #SDCC2022 at the Embassy Suites Happy Hour. 655 ppm CO2. I made myself an outdoor happy hour just outside the doors to enjoy some San Diego weather.

End of Day 4 for me! Double fisting a suitcase in one hand and a margarita in the other to very very slowly make my way outta dodge. Overall on the air quality side + mask compliance I've been impressed by what #SDCC2022 has been able to achieve in comparison with that other con

I measured Hall H on Friday, then portions of the Exhibit Hall and Sails Pavilion throughout the convention. I measured Room 6BCF on Saturday. I did not measure Ballroom 20 or any other smaller panels.

Con side lessons: the exhibit hall is overall better in CO2 ppm to the G side, with readings of 800 ppm to 900 ppm. The A side was around 1000 ppm to 1100 ppm. The worst areas were in the 1300 ppm range by the 3300s middle of the exhibit hall.

Con lessons 2: during all-day sessions of elastomeric mask wearing, it is important to have a change of moisture absorbing pads for your face piece and a small hand towel ready to wipe your face periodically. I used this Marushin towel every 45 min and it did the job pretty well.

Con lessons 2: the Angelus paint is durable to a point, and that is when the ambient humidity comes into play. There are these two weak points at the upper part of the harness cage that need reinforcement when masking / unmasking frequently.

Con lessons 4: Even if you take a grip of rapid covid tests with you, all you can measure is what your hotel roommates came with, not whether they picked up anything new at-con. Woops.

SDCC is really proving itself to be the premier pop culture convention in the world. In the next couple days we will see the results of the work put into mask enforcement at-con. In the end if Comic Con can do it, it can serve as a model for other conventions in the world.
