  - (2) **The significant new uses are—**
    - (i) **Protection in the workplace.** Requirements as specified in § [721.63 (a)(1)](/cfr/40/721.63.md?p=a-1), [(a)(2)(i)](/cfr/40/721.63.md?p=a-2-i), [(a)(2)(iii)](/cfr/40/721.63.md?p=a-2-iii), [(a)(2)(iv)](/cfr/40/721.63.md?p=a-2-iv), [(a)(3)](/cfr/40/721.63.md?p=a-a-3), [(b)](/cfr/40/721.63.md?p=a-a-b) (concentration set at 1.0 percent), and (c). However, the personal protective clothing required in [paragraph (a)(2)(iv)](#a-2-iv) must be tested or evaluated under the requirements of paragraph (a)(3). Furthermore, the imperviousness of gloves required under [paragraph (a)(2)(i)](#a-2-i) may not be demonstrated according to paragraph (a)(3)(ii), but rather must be tested according to paragraph (a)(3)(i) with the following additional requirements: There must be no permeation of the PMN substance greater than 16 ppb after 8 hours of testing in accordance with the American Society for Testing and Materials (ASTM) F739-85 “Standard Test Method for Resistance of Protective Clothing Materials to Permeation by Liquids or Gases.” Gloves 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.
    - (ii) **Hazard communication program.** Requirements as specified in § [721.72 (a)](/cfr/40/721.72.md?p=a), [(b)](/cfr/40/721.72.md?p=b), [(c)](/cfr/40/721.72.md?p=c), [(d)](/cfr/40/721.72.md?p=d), [(e)](/cfr/40/721.72.md?p=e) (concentration set at 1.0 percent), (f), (g)(1)(iv), (g)(2)(i), (g)(2)(iii), (g)(2)(v), (g)(3)(ii), (g)(4)(i) and (g)(5).
