Which regulatory agency sets the standards for electrical safety in control systems?

The correct answer, which pertains to the agency that sets the standards for electrical safety in control systems, is OSHA. The Occupational Safety and Health Administration is responsible for ensuring workplace safety and health, and it provides guidelines and regulations to protect workers from electrical hazards. OSHA's regulations include standards related to electrical safety that must be followed by employers.

In the context of control systems, adhering to OSHA standards helps prevent electrical accidents and ensures safe practices are implemented when working with electrical components and systems. This includes protocols for installation, operation, and maintenance of electrical systems, ultimately aimed at safeguarding personnel and enhancing overall safety in facilities where control systems are utilized.

Other options mention entities that have different roles. For instance, NIST (National Institute of Standards and Technology) focuses on developing standards for measurement and quality but does not specifically deal with electrical safety regulations. ISA (International Society of Automation) provides guidelines and best practices for automation and control systems but is not a regulatory body. The NEC (National Electrical Code) establishes standards for safe electrical design, installation, and inspection, but it is not a regulatory agency like OSHA; rather, it serves as a reference code that jurisdictions adopt, often enforced under OSHA’s broader safety regulations.
