Shearing sheds (or wool sheds) are large sheds located on sheep stations to accommodate large scale sheep shearing activities. In countries where large numbers of sheep are kept for wool, sometimes many thousands in a flock, shearing sheds are vital to house the necessary shearing equipment, and to ensure that the shearers and /or crutchers have a ready supply of dry, empty sheep. The shed also provides space where the wool is classed and pressed into approved wool packs and stored to await transport to market. Location of the shed is important as the site needs to be well drained and in an area reasonably close to most of the flock. It is helpful and will save a lot of money if the shed is located near to the electricity supply. At least some yards will be needed to facilitate shedding and count-outs. Regional variants of shearing shed architecture throughout Australia and New Zealand have been identified through different uses of building materials and local styles of design. During recent years occupational safety and health and animal welfare issues in Australia also have to be considered during shed building or renovating. There should be guard rails around raised shearing boards and loading landings should be fenced to prevent falls. Separate facilities are to be provided for workers' meals. Sheep penning area It is usually regarded as necessary to be able to shed, and keep dry, sheep for two days of shearing. Wet or damp sheep may cause health problems for the shearers and damp wool can't be pressed. In many instances sheep are held under the shed or in an adjacent area known as a sweating shed. In the shearing shed the woolly sheep will be penned on a slatted wooden or woven mesh floor above ground level. The sheep entry to the shed is via a wide ramp, with good footholds and preferably enclosed sides. After shearing the shearing shed may also provide warm shelter for newly shorn sheep if the weather is likely to be cold and/or wet. In recent years shearing sheds have usually included improved penning systems to assist with the movement of sheep and ideally will include swing/slide gates to facilitate their closure. A single sheep is sometimes penned in a small pen at the front of the forcing lane to coax the other sheep forward. The slats in a catching pen run in the
