Glovebox Air Change
Glovebox Air Change
(OP)
I am designing a crude glovebox and I am trying to figure out how to make calculations for the air change. Are there standards for what the air change should be?
Here is the situation:
Our area is currently pour 1 gallon of powered acid into a mixing tank filled with water. In order to prevent powered acid particulates from getting on the employee, I am designing a glovebox to go on top of the tank opening. I have a port for our HEPA vacuum (87 cfm) hose to attach to the glovebox and another port to allow for ambient air to crossflow into the glovebox during suction. I am trying to calculate when the air would be safe inside the glovebox. The employee would pour the acid into the tank, remove their hands from the gloves, open the ambient air port, and turn on the vacuum at the vacuum port.

Safety first. Money not important. Keep that in mind! $30,000 to $70,000 will look like pennies if an employee gets acid dust on him or her. Even or worse will be if that employee inhales some. This is so, even if you're only going to use it a few times.
I'd be wearing full personal protective gear, as if there were no glove box.
