Material Safety Data Sheet

The handling of this chemical may incur notable safety precautions. It is highly recommend that you seek the Material Safety Datasheet (MSDS) for this chemical from a reliable source such as SIRI, and follow its directions.

gollark: It would be neat if mesh networking was more practical.
gollark: There was also somewhat less carbohydratey stuff (bread/pasta) available for a bit, as far as I could tell.
gollark: (although marmite rice cakes seem to be missing now?)
gollark: People were complaining about supply chain disruption and how clearly everywhere needs to be self-sufficient during the start of the whole people-noticing-COVID-19 thing, but it seems like, on the whole, there was mostly food and stuff around and it got resolved fairly fast.
gollark: Stuff does manage to mostly function, most of the time, somehow.
