Machine guards are safety devices designed to protect workers from hazards associated with machinery. They prevent accidental contact with moving parts, reducing the risk of injuries such as cuts, crushes, or entanglements. Guards can be fixed, adjustable, or removable, depending on the type of machine and the level of access needed for operation or maintenance. These guards are essential in various industries, including manufacturing and construction, where heavy machinery is commonly used. By ensuring that machines like lathes, saws, and conveyors are properly guarded, employers can create a safer work environment and comply with safety regulations.
