packed with an iron drum or a wooden drum lined with a polyethylene plastic bag, or packed with a plastic woven bag lined with a polyethylene plastic bag, the net weight of each barrel (bag) is 40kg and 50kg. Containing free acid> 30% is acid corrosion products. Risk code: GB Class 8.1. UN N0 1974; IMDGCODE 8189 pp., Category 8.1. Store in a ventilated, dry warehouse. It is not allowed to be stored and mixed with edible articles. When there is a fire, it can be suppressed by using water or various kinds of fire retardants. Lead and its compounds are toxic to all organisms. In particular, can make the nervous system, blood, blood vessels change. The maximum allowable concentration of lead and its inorganic compounds is 0.01 mg/m2. The average concentration at work was 0.007mg/m3. Operators should wear masks. When the vapor concentration is high, fresh air is forcibly supplied using a filter-type gas mask.
