as booth shelves or target retrieval systems, are heavily used, they can require regular cleaning. Cleaning should be done once or twice a week otherwise. Wet methods or a vacuum fitted with a high-performance particulate air (HEPA) filter may be used to clean. The risk of unburned powder accumulating necessitates the use of an explosion-proof HEPA vacuum. The vacuum should be used solely for the removal of lead dust. Cleaning personnel should be well trained and not attempt to rush the process. Dry sweeping or "blowing down" the range with compressed air should be forbidden. Brooms should not be used to clean spent shell casings ("brass") (a wooden "casino rake" can be useful). During cleanup, the ventilation system should be turned on. Personnel and shooters should be aware of the areas of the range to which they are permitted entry, as well as the areas where their clothing or skin may become contaminated. Shooters should not be permitted to proceed beyond the firing line. Individuals who might need to walk down the range should have disposable shoe coverings accessible. Before consuming food, drinks, or other products, shooters should thoroughly wash their hands and face. Personnel can vacuum off their garments with a HEPA vacuum before leaving the range for operations where contamination is possible. Vacuuming can help to keep lead dust from spreading to other parts of the house, as well as personal vehicles and quarters. Safety areas Safety areas are own places on shooting ranges where a small bay with a safe direction is set up for shooters to be able to handle unloaded firearms without the supervision of a Range Officer (RO). Safety areas are widely used in dynamic shooting sport disciplines and PPC 1500, and may for example be used to pack, unpack or holster a gun, cleaning or repair, dry firing and training with empty magazines Specialized classes and licenses This will vary by country; for example, in some countries, using a shooting range does not require a license or specialized training beyond gun refresher training (for rental guns) and range rules familiarization. In other countries, participants must be part of an organized club and must hold licenses for ownership of individual firearms. A common requirement is that the shooter must be of legal age (or have a guardian present) prior to shooting. In the United States, training classes for a concealed carry license are often
