NFPA-99 Practice Exam

What does it mean when equipment is shown as listed?

1. Identified and published by an organization accepted by the AHJ.

2. Found acceptable for the purposes described in the manufacturer's specifications.

3. Approved by the construction supervisor.

4. Tested by a medical gas verifier.

The correct answer is: Identified and published by an organization accepted by the AHJ.

When equipment is shown as listed, it signifies that the equipment has been identified and published by an organization that is recognized as acceptable by the Authority Having Jurisdiction (AHJ). This means that the equipment has undergone a rigorous evaluation process by a third-party organization, ensuring it meets specific safety and performance standards relevant to its intended use. This listing typically involves testing the product against industry standards and verifying that it meets all applicable codes and requirements. The listing provides assurance to end-users and regulatory bodies that the equipment is safe and reliable for use in critical environments, such as healthcare facilities covered under NFPA 99. The recognition by an authoritative organization lends credibility and trust in the equipment’s performance, helping to ensure compliance with standards that protect patients and healthcare workers alike.
