Who has developed a national performance standard (for cabinets)?

• A. NSF
• B. ANSI
• C. OSHA
• D. EPA

Answer: (A)

NSF International is the organization that develops and maintains national performance standards for safety cabinets, including those used to store flammable and hazardous materials. They publish the standards and require third‑party testing, so cabinets that pass earn the NSF certification mark, signaling they meet defined criteria such as fire resistance, spill containment, and secure construction. OSHA references these kinds of standards in regulation, but doesn’t create the cabinet performance standard itself. ANSI is a standards developer in general, but the specific cabinet performance standard most commonly used and cited is NSF’s. That’s why NSF is the correct choice.
