WAC 296-835-13030
Control liquid spray over an open surface
cleaning or degreasing tank.
You must:
• Control the spray to the greatest extent feasible by:
– Enclosing the spraying operation as completely as possible
– Using mechanical ventilation to provide enough inward air
velocity to prevent the spray from leaving the vapor area.
Note:
Mechanical baffles may be used to help prevent the discharge of spray.
Reference: Spray painting operations are covered in Spray
finishing using flammable and combustible materials, WAC 296-24-370, and Spray-finishing operations, WAC 296-62-11019.
