Safety tips: PVA has no significant toxicity or special hazard, but the operator should avoid inhaling a large number of its dust, and contact with the skin or the eye directly as the the chemical may irritate, or cause you unwell such as difficult breathing and so on.
Do not discard anywhere, otherwise the dust will fly about and cause air pollution
Keep off fire, or it will burn.
Storage: PVA products can be packed with filmed plastic woven bag, composite paper-plastic bag or paper bag. The net weight of flocculent PVA is 25kg or 20kg per bag, and 25kg or 20kg for flake and powder products. The manufacturing date and batch NO. Are marked on the pack.
