Machine safeguardsmust meet these minimum general requirements: The type of operation, the size or shape of stock, the method of handling, the physical layout of the work area, the type of material and production requirements or limitations help determine the best method for safeguarding. European Committee for Standardization (CEN). Posts shall be not more than eight (8) feet apart; they are to be permanent and substantial, smooth, and free from protruding nails, bolts, and splinters. Belt drives and chain drives used to power the head pulley are common maintenance locations with significant entanglement risks. A thorough hazard analysis of each machine and situation is essential before using this safeguarding technique. The process of adopting nip point guarding as well as peripheral guarding has been progressive, usually in response to an accident resulting from ineffective or missing peripheral guards. The vertical clearance in passageways between the floor and power transmission beams, ceiling, or any other objects, is not less than five feet six inches (5 ft. 6 in.).

Create no interference: Any safeguard that impedes a worker from performing a job quickly and comfortably might be bypassed or disregarded. While there are many different kinds of conveyor systems, they usually consist of a frame that supports either rollers, wheels, or a belt, upon which materials move from one place to another. Additionally, small particles of the material carried by or embedded in the surface of the belt, including dirt and grit that may be carried onto belts used for unit loads such as cardboard boxes, can increase the abrasiveness of the belt. 0000069382 00000 n Recognizing the danger and preventing injury. The Occupational Safety and Health Administrations (OSHAs) requirements for machine guarding are found in 29 Code of Federal Regulations (CFR) 1910 Subpart O, Machinery and Machine Guarding as detailed below; 29 CFR 1910.212(a)(1) states that one or more methods of machine guarding must be used to protect operators and other employees from hazards, including those created by point of operation, in-running nip points, rotating parts, flying chips and sparks. This danger is common on machines with intermeshing gears, rolling mills and calendars. The belts are looped over pulleys attached to the driver and follower shafts. Approximately 75 percent of struck-by fatalities involve: Heavy equipment, such as trucks or cranes. Often, with older machines, they are the only practical solution.
