Machine guarding refers to the use of physical barriers or safety devices to protect workers from hazards associated with operating machinery. These guards can prevent accidental contact with moving parts, flying debris, or other dangerous elements, ensuring a safer work environment. Effective machine guarding includes features like safety interlocks, emergency stop buttons, and protective enclosures. Employers are responsible for implementing these safety measures to comply with regulations and reduce the risk of workplace injuries. Regular inspections and maintenance of guards are essential to ensure they function properly and provide adequate protection.
