Open Data Verified Data
- basically non-toxic, rat oral ld5011500 mg/kg. J acid is packed in wooden cases or iron barrels lined with plastic bags, with a net weight of 60 (40) kg per box (barrel), and the mouth of the bag should be double tied. It shall be transported in clean, capped vehicles. When loading and unloading must be light up and down.
- store in a dry, clean house to prevent exposure to the sun and rain. When placed, the box (barrel) mouth is upward to avoid product leakage.
