HANDLING/STORAGE CAUTIONS: Harmful or fatal if swallowed, inhaled, or absorbed through skin. May cause eye irritation. Avoid eye, skin, clothing contact. Wash thoroughly after handling. Do not breathe dust. Use with adequate ventilation. Repeated careless use may cause cholinesterase inhibition. Biological activity remains practically unvaried for 2 years under environmental conditions if stored in unopened, undamaged original containers, in shaded, cool, well-aired places, inaccessible to animals and unauthorized persons. Recommended temperature <25℃. Crystals may form in formulations stored at <0℃. Stable for minimum of 1 year at <25-30℃. Will decompose rapidly when heated to temperatures above 80℃ and explosion may be induced. Never heat above 35℃ and local heating should be avoided. Stack containers to permit air circulation at bottom and inside of piles. Do not contaminate food or feed. | |
