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.
