4. Security
Oral LD50:600-700mg /kg (S02) for rabbits. ADI 0 ~ 0.70 mg/kg (in S02, including total ADI} of S02 and sulfite FAO/WHO, 1999).
Use Uchimura polyethylene plastic bags (plastic bags should be double pierced), sealed tightly stamped iron drum packaging, iron sheet thickness is not less than 0.7 mm. The net weight of each barrel is 50kg. It is a second-class water-burning article, hazardous code number: GB4.2 class 420120 UN N0.13840 IMDGCODE page 4262, class 4.2 (domestic according to 4.3 class 43041 treatment). It should be stored in a cool, ventilated and dry warehouse. Prevent moisture, prevent direct sunlight, away from fire, do not contact with water or steam, do not store and transport with oxidants or other flammable goods. Tie and cover the mouth immediately after use and keep it properly. When fire, do not use water, need to use sand, carbon dioxide clamour to fight. Toxicity and dosage: Food grade products according to the national standard GB 2760-86 provisions: used as bleaching agent for sugar, candy, cookies, canned, bamboo shoots, mushrooms, etc., dosage is 0. 4G /kg. For residual amount, see anhydrous sodium sulfite.
