Woodshop Hazardous Material Authorization

It says I need a class to work with materials on the hazardous list. When is the next class for this?

I have rolled that subject into the normal woodshop safety class these days. I tell people that the sheet on the door is for writing down a hazardous material that a person used, so other members can check to see if anything they have a concern about breathing in over time has been used recently. You can also write down any material that you think is exotic.

Just normal woodshop safety is now required for the woodshop to get started in the woodshop. And it looks like I need to set up some more authorization classes.
