Disinfection & SafetyQuestion 16 of 100

You file acrylic all day and the trash at your station is an open basket of acetone-soaked cotton. What should you change?

a.Use a covered waste can with a self-closing metal lid, empty it daily, and wear an N95-type dust mask while filing
b.Aim a ceiling fan at your station to move the vapors around the room
c.Rely on the dust mask alone to protect you from the acetone vapors
d.Prop the front door open and leave the basket where it is

Explanation

Chemical-soaked cotton belongs in a covered waste container with a self-closing metal lid that is emptied every day, and an N95-type mask should be worn for filing dust. A ceiling fan only stirs vapors around instead of capturing them at the table, which is what source-capture ventilation does. A dust mask filters particles, not vapors, so it cannot be your protection against acetone fumes.
