What does NFPA 1192 5.2.1 require about the installation of propane systems?

The requirement in NFPA 1192 5.2.1 emphasizes compliance with specific water capacity limits for propane systems. This standard ensures that the installation of propane systems is safe and adheres to regulations meant to prevent hazards associated with improper storage and use of propane. By enforcing these water capacity limits, NFPA 1192 helps to minimize risks such as overfilling and potential leaks, contributing to the overall safety of propane systems.

In contrast, the other options do not align with the specific focus of this provision. User maintenance, the number of cylinders, and the requirement for professional certification are not governed under this particular section of the standard. Instead, NFPA 1192 targets the technical specifications and safety measures necessary to safely accommodate propane cylinder installations.
