What is the maximum LP Gas water capacity for a container that can be connected to any single manifold at a permanent installation on a roof using portable containers?

In the context of LP gas installations, regulations specify limits on the water capacity of containers to ensure safety and compliance with applicable codes. The maximum capacity for a container that may be connected to a single manifold at a permanent installation on a roof using portable containers is established based on safety considerations.

The correct answer of 400 pounds reflects the accepted limit for portable LP gas containers used in such permanent installations. This regulation helps prevent potential hazards associated with overcapacity and ensures that the gas system operates within safe parameters. Containers exceeding this weight might pose risks regarding structural load and potential leaks or explosions, which can arise from improperly managed gas storage in high-density areas.

While options such as 300 pounds, 350 pounds, and 450 pounds represent either lower or higher limits, they do not meet the established safety criteria for this specific scenario, highlighting the importance of adhering to regulatory standards set forth for LP gas usage in permanent installations.
