Which organization sets the standard for the testing interval of mercury gauges on tanks?

• A. OSHA
• B. NFPA
• C. ANSI
• D. UL

Answer: (B)

Testing intervals for gauges on fire protection system tanks are defined by a maintenance standard, not general safety rules or product certs. NFPA 25 lays out the inspection, testing, and maintenance requirements for water-based fire protection systems, including how often gauges and level indicators should be checked to ensure accuracy and reliable operation. This makes NFPA the reference for how often mercury gauges on tanks should be tested. OSHA focuses on overall safety regulations, not specific component testing schedules; ANSI and UL deal with product standards and certification rather than field maintenance intervals.
