Section 340-232-0180 - Degreasers
Current through Register Vol. 63, No. 3, March 1, 2024
Cold cleaners, open top vapor degreasers, and conveyorized degreasers are exempt from this rule if they use fluids which are not photochemically reactive. These fluids are defined in the definition of VOC under OAR 340-200-0020.
(1) The owner or operator of dip tank cold cleaners must comply with the equipment specifications in this section:
(2) An owner or operator of a cold cleaner must follow the required operating parameters and work practices. The owner must post and maintain in the work area of each cold cleaner a pictograph or instructions clearly explaining the work practices in this section:
(3) The owner or operator must maintain cold cleaners in good working condition and free of solvent leaks.
(4) If the solvent has a volatility greater than 2.0 kPa (0.3 psi) measured at 38° C. (100° F.), or if the solvent is agitated or heated, then the cover must be designed so that it can be easily operated with one hand or foot.
(5) If the solvent has a volatility greater than 4.3 kPa (0.6 psi) measured at 38° C. (100° F.), then the drainage facility must be internal, so that parts are enclosed under the cover while draining. The drainage facility may be external for applications where an internal type cannot fit into the cleaning system.
(6) If the solvent has a volatility greater than 4.3 kPa (0.6 psi) measured at 38° C. (100° F.), or if the solvent is heated above 50° C. (120° F.), then one of the following solvent vapor control systems must be used:
