NFPA-99 Practice Exam

When can an existing medical gas system continue to be used despite not being in strict compliance?

1. If it is deemed not a significant hazard to life by the authority having jurisdiction

2. If the chief administrator of the facility approves it

3. If proper signage is posted only

4. If no complaints have been raised

The correct answer is: If it is deemed not a significant hazard to life by the authority having jurisdiction

An existing medical gas system can continue to be used despite not being in strict compliance when it is deemed not a significant hazard to life by the authority having jurisdiction. This standard is crucial because it ensures that patient safety remains the top priority. The authority having jurisdiction (AHJ) is responsible for enforcing safety regulations and standards to minimize risks associated with medical gas systems. If the AHJ assesses that the system, despite its non-compliance, does not pose a considerable risk to life and health, it may allow continued use under specified conditions. The other options do not provide sufficient justification for the continued use of a non-compliant medical gas system. The chief administrator's approval might indicate a level of management support, but it does not replace the need for a safety assessment by the AHJ. Simply posting proper signage might inform users of potential hazards but doesn’t address the underlying compliance issues, and basing continuation solely on the absence of complaints does not ensure that the system is safe to use. Therefore, the assessment by the AHJ is the basis for allowing continued operation, emphasizing safety and regulation adherence.
