Construction contractors using coal and coke as fuels for energy purposes (equipment) or heating oil, they collect as recommended by superior authorities or as the program of rebuilding stocks for the winter works period is implemented, larger amounts of solid fuels. This is dictated by the increase in fuel consumption in this period and the need to use PKP means of transport before the autumn-winter peak of transport. Storage of larger amounts of fuels for longer periods requires rational arrangement of landfills on bases, intended for this purpose in advance. The device of the landfill is aimed at: a) the prevention of lawlessness and theft, b) avoiding carbon indentation into soft ground and avoiding spontaneous combustion and the resulting losses. This description concerns the method of storing solid fuels in dumps (prisms) under the open sky, as most used.: on construction sites and bases of construction contracting units. Other, methods of storing solid fuels that are less or not used in construction (in heaps under the roof, in tanks and closed rooms), are specified in the Polish Standard. In landfills, where solid fuels are stored for shorter periods; than 7 days, and in smaller quantities, at least the following essential storage conditions should be respected: a) the yard designated for the coal storage facility should be cleaned, aligned, hardened (rolled up) and fenced, b) fuel should be dumped in strictly defined places in the storage yard, in regular piles, segregating separate assortments, c) access roads should allow access to each pile, d) fuels should be sheltered from the wind, e) should be guaranteed easy and. efficient dispensing and receiving of fuels (landing, loading and ease of traversing the inventory), f) loading and unloading of fuels should be done in a way that prevents crushing of fuel lumps. When storing, remember to divide coal into grades according to the Polish Standard.
