Emergency treatment plan for lead leakage in lead blocks? 
      Cut off the fire. Wear a gas mask and a normal fire protection suit. Collect in a dry, clean container with a clean shovel and cure with cement, asphalt or appropriate thermoplastic material before disposing. Such as a large amount of leakage, collection and recycling or harmless disposal after waste.

① For leaking PbCl4 and Pb(ClO4)2, all protective equipment such as gas mask should be worn. Mix with dry sand and pour into large amounts of water in small batches. Dilute the waste water and put it into the waste water system.

② For the leakage of PbO, tetraethyl (B) base lead and Pb3O4, should wear a good gas mask and other protective equipment. Mix with dry sand and dump it in an open area. The contaminated ground is scrubbed with soap or detergent, and the diluted sewage is put into the waste water system.

③ For leaking PbF2, all protective equipment such as gas mask should be worn. Sprinkle the spill with soda ash; The contaminated ground is washed with water and the diluted sewage is put into the waste water system.

(4) For leaking Pb(BrO3)2, PbO2 and Pb(NO3)2, all protective equipment such as gas mask should be worn. The contaminated surface is washed with water and the diluted sewage is put into the waste water system.

⑤ For the leaked alkyl lead, scrub the emulsion made of non-combustible dispersant. If there is no dispersant can be absorbed by sand, pour to the open place buried; The contaminated ground is scrubbed with soap or detergent and the diluted sewage is put into the waste water system.

Treatment method: When the water is polluted, the neutralization method can be used for treatment, that is, adding lime milk to adjust the pH to 7.5, so that the lead precipitates in the form of lead hydroxide and transfers from the water to the sludge. Mechanical stirring can accelerate the clarification, and the concentration of lead in treated water is 0.37 ~ 0.40mg/L. The sludge is then treated with further harmless treatment. For lead-contaminated soil, amendments such as lime and phosphate fertilizer can be added to reduce the activity of lead in soil and reduce the absorption of lead by crops
