§ 721.5185 2-Propen-1-one, 1-(4-morpholinyl)-.

(a) Chemical substance and significant new uses subject to reporting. (1) The chemical substance identified as 2-propen-1-one, 1-(4-morpholinyl)- (PMN P-95-169; SNUN S-08-7; SNUN S-14-1; and SNUN S-17-10; CAS No. 5117-12-4) is subject to reporting under this section for the significant new uses described in paragraph (a)(2) of this section. The requirements of this rule do not apply to quantities of the chemical substance after it has been completely reacted (cured) because 2-propen-1-one, 1-(4-morpholinyl)- will no longer exist.

(2) The significant new uses are:

(i) Protection in the workplace. Requirements as specified in § 721.63(a)(1), (a)(2)(i) and (iv), (a)(3)(i) and (ii), (a)(6)(v), (b), and (c).

(A) Safety 4/4H EVOH/PE laminate, Ansell Edmont Neoprene number 865, and Solvex Nitrile Rubber number 275 gloves have been tested in accordance with the American Society for Testing Materials (ASTM) F739 method and found by EPA to satisfy the consent orders and § 721.63(a)(2)(i) requirements for dermal protection to 100 percent PMN substance. Gloves and other dermal protection may not be used for a time period longer than they are actually tested and must be replaced at the end of each work shift. For additional dermal protection materials, a company must submit all test data to the Agency and must receive written Agency approval for each type of material tested prior to use of that material as worker dermal protection. However, for the purposes of determining the imperviousness of gloves, up to 1 year after the commencement of commercial manufacture or import, the employer may use the method described in § 721.63(a)(3)(ii), thereafter, they must use the method described in § 721.63(a)(3)(i). For purposes of § 721.63(b), the concentration is set at 1.0%.
