When must public access be prohibited to areas where LP-gas is stored and transferred?

Public access must be prohibited to areas where LP-gas is stored and transferred at all times due to safety considerations. This measure is crucial to prevent unauthorized access, as LP-gas is highly flammable and poses significant hazards if not managed properly. By restricting access, the risk of accidents, such as leaks or explosions, is minimized, and it helps ensure that only trained personnel are in the vicinity to handle the gas safely.

This constant restriction is in line with the safety guidelines outlined in NFPA 58, which emphasize the importance of securing LP-gas facilities to protect both the public and the environment from potential hazards associated with liquefied petroleum gas. Therefore, any suggestion of allowing public access during certain times or occasions—such as only during maintenance or at night—does not adequately address the ongoing risk associated with LP-gas. The correct approach is to maintain stringent access control at all times to uphold safety standards and prevent dangerous incidents.
