Generally, PPC Lime s contractor s road trucks are fitted with blowers to aid with the offloading. Customers therefore need not have blowers onsite. It is important that lime is stored in an enclosed dry area. Unslaked lime reacts with water (including atmospheric moisture), producing heat and strongly alkaline hydrated lime. Care should always be excercised when handling this product.
