OAR 437-002-0287: Toxic Preservative Coatings

(1) In confined and other enclosed spaces, preservative coatings that are toxic but not highly flammable must be removed: (a) A distance of at least 4 inches from the area of heat application; or (b) A greater distance, if that is necessary to prevent the production of toxic fumes and gases. (2) As an alternative to stripping the coating, the employer can choose to protect all affected employees by requiring the use of appropriate respiratory protection in accordance with the Respiratory Protection Standard, 1910.134. Note: Artificial cooling of the metal surrounding the heated area may be used to limit the size of the area that must be stripped. Note: “Coated Steels” are excluded from these requirements unless the manufacturer’s safety data sheet designates the product as a health hazard when heated.
