For purposes of § 721.72(g)(2), the required human health precautionary statements include: Use skin protection; where engineering controls are not determined to be adequate, use respiratory protection. For purposes of § 721.72(g)(3), the required environmental hazard statements include: This substance may cause long lasting harmful effects to aquatic life. Alternative hazard and warning statements that meet the criteria of the Globally Harmonized System and OSHA Hazard Communication Standard may be used.

(iii) Industrial commercial, and consumer activities. It is a significant new use to process or use the substance with an application method that generates a mist, vapor, or aerosol.
