What standard outlines requirements for the design and installation of machine guards?

The standard that outlines requirements for the design and installation of machine guards is the OSHA 1910 standard. This regulation is part of the Occupational Safety and Health Administration's general industry standards, specifically addressing various workplace hazards, including those related to machine operations. OSHA 1910 emphasizes the importance of proper guarding to protect employees from moving parts, mechanical hazards, and potential injuries associated with machinery.

ANSI/ASSE Z490.1, while relevant to safety training and the development of safety programs, does not specifically focus on machine guard design or installation. ISO 9001 relates to quality management systems, and while it addresses how to manage quality in processes and products, it does not provide guidelines on the engineering requirements for machine guards. NFPA 70E deals with electrical safety in the workplace and is focused on safe work practices regarding electrical hazards, not mechanical guarding.

Therefore, OSHA 1910 is the standard that primarily governs the requirements for the design and installation of machine guards, ensuring a safer working environment in industries that utilize machinery.
