What is an example of a Grade 1 LP-gas leak?

In the context of the NFPA Liquefied Petroleum Gas Code (NFPA 58), a Grade 1 LP-gas leak is classified as a leak that requires prompt action to protect life and property. This designation indicates that the leak poses an immediate and significant risk, necessitating urgent measures to ensure safety.

When a leak is identified as Grade 1, it indicates that the leak could potentially create dangerous conditions, such as the risk of explosion or fire, and therefore must be addressed immediately. This could involve shutting off the gas supply, evacuating the area, or implementing emergency response protocols.

In contrast, the other options represent leaks of lesser concern. A minor leak requiring monitoring might not require immediate action, while a visual inspection deemed adequate suggests that the situation is currently safe without further intervention. Finally, acknowledging a leak that can be repaired later implies there is no urgent threat, which does not align with the seriousness of a Grade 1 classification. Thus, only the prompt action to protect life and property appropriately fits the definition of a Grade 1 LP-gas leak.
