Does OSHA mandate the use of a Safety Instrumented System (SIS)?

• A. Yes, for all industries.
• B. No, but industry standards must be followed.
• C. Only for chemical manufacturing.
• D. Yes, under all circumstances.

Answer: (B)

The correct answer indicates that while OSHA (Occupational Safety and Health Administration) does not explicitly mandate the use of Safety Instrumented Systems (SIS), it does require compliance with certain industry standards that may call for their implementation. OSHA's focus is on ensuring safe working conditions and preventing workplace accidents. In many industries, particularly those involving hazardous operations such as chemical manufacturing and oil and gas, industry-specific standards like those from the International Society for Automation (ISA), particularly IEC 61511 for the process industry, outline best practices for safety instrumented systems. Organizations are expected to follow these standards to achieve compliance with OSHA's general duty clause, which mandates that employers provide a workplace free from recognized hazards. Thus, while OSHA may not mandate SIS in a blanket manner across all industries, it recognizes the importance of adhering to these industry standards to maintain safety and effectively manage process risks.
