Luke Holson raised a concern about fumes back venting through the Zing and possible carbon monoxide production.
I’ve gone ahead and tagged the thunder laser as out of service and to check out this talk thread.
Temporary countermeasure might be to run Zing ventilation at the same time. I personally believe that you could safely cut with the ventilation system in place, but I wanted to raise the concern since it’s safety related. Not sure what the proposed permanent countermeasure would be.
