To blast in a blast room, you must wear a protective suit – I wear a Tyvek suit with a hood (see photo below). You also need a respirator mask, half-face or full-face, which is hooked up to a special air pump that produces safe breathing air from outside the blasting environment. Lastly, I advise wearing a helmet with a face shield to protect your eyes during blasting.
