Part 18 Personal Protective Equipment

Section 255 Abrasive blasting operations

Workers performing abrasive blasting operations must wear a protective hood that supplies air at a positive pressure of not more than 140 kilopascals (20 pounds/square inch). No minimum pressure is specified for the hood. However, a positive pressure should always be maintained in the hood to prevent dust from entering the hood and being inhaled.
