3. Adjust tension on both top and bottom straps to provide a tight and comfortable seal. To tighten, pull ends of straps. To loosen, push open hinge of buckle with thumb and pull on strap.

Repeat until sealed properly, otherwise do not enter work area and see your supervisor. Entry into a contaminated area with an improper fit may result in sickness or death.
