Which safety standard is commonly followed in automation technology?

The commonly followed safety standard in automation technology is IEC 61508. This standard focuses on the functional safety of electrical, electronic, and programmable electronic safety-related systems. It provides a framework for managing risks associated with hazards that are inherent in automated and control systems. The standard outlines a lifecycle approach to safety, which includes stages such as concept, design, implementation, and operation, ensuring that safety considerations are integrated from the very start of the development process.

IEC 61508 is essential for industries where failure of safety systems can lead to catastrophic outcomes, including processes like manufacturing, transportation, and energy. By adhering to this standard, organizations can better ensure the reliability and safety of their automation technologies, reducing the likelihood of accidents and enhancing overall operational safety.

In contrast, the other standards mentioned have different focuses. ISO 9001 pertains to quality management systems, ANSI Z535 deals with safety signage and symbols, and ISO 14001 focuses on environmental management systems. While these standards are important in their own right, they do not specifically address the complex safety concerns inherent in automation technology in the same manner as IEC 61508 does.
