Store in a cool, ventilated warehouse. Keep away from tinder, heat sources. It should be stored separately from oxidants and alkalis, and mixed storage should be avoided. Equipped with fire fighting equipment of corresponding varieties and quantities. Storage areas should be equipped with suitable materials to contain spilled materials.

Packed in plastic bags, cloth bags or polypropylene woven bags, each bag is 20kg. Store in a cool, ventilated and dry place. Heatproof, sunscreen, moisture-proof. Storage and transportation according to the provisions of general combustible chemicals.

1. Avoid contact with strong oxidants and alkalis.

2. This product is low toxicity, and its toxicity is basically the same as phthalic acid. Oral LD506.0g/kg for rats. The lethal dose of intraperitoneal injection is 800mg/kg. The irritation to the skin is not as strong as phthalic acid, and it does not show sensitization. Allergic symptoms, wheezing, ulcers, etc. that occur in the production process are caused by impurities of raw materials, and can be decomposed and detoxified in the same way as phthalic acid in living organisms. For people with allergies, contact with this product can cause rash or bronchial asthma or bronchitis. Dust masks should be worn during operation. The maximum allowable concentration in air is 0.1mg/m3.
