Lime easily affects the skin and also is a health hazard if breathed in. The moisture on the body reacts with lime resulting in skin diseases. This may be avoided by coating the skin with oil.
Slaking of lime is an exothermic reaction, i.e., it produces a large amount of heat. Necessary precautions should be taken by workers who are involved in the use of lime. It is customary to use goggles, respirants, gloves and boots as protection.
5.7 STORAGE OF LIME
Quicklime should be kept in air-tight vessels or in large heaps under cover; otherwise, it should be slaked soon after delivery or run into putty to prevent deterioration.
Slaked lime can be stored safely for 3–4 months if packed in gunny bags lined with polythene, craft paper, etc. The storing should be done in weather-proof sheds, which are perfectly dry. As per specifications, the lime should be slaked not less than 1 week and not more than 4 weeks before its use.
Hydrated lime can be safely stored for considerable time without deterioration provided the bags are kept in a dry place.
