What is the required ratio of Ethyl Mercaptan in LP Gas as measured per 10,000 gallons?

The required ratio of Ethyl Mercaptan in LP Gas is established to ensure effective odorization of the gas for safety purposes. Ethyl Mercaptan is a recognized odorant that gives natural gas its distinct smell, allowing consumers and service personnel to easily detect gas leaks.

The standard requirement is set at one pound of Ethyl Mercaptan per 10,000 gallons of LP Gas. This concentration is sufficient to provide a detectable odor that alerts individuals to potential leaks, thus promoting safety in handling and using LP Gas. By using this specific amount, regulations are aimed at ensuring that LP Gas remains safe for consumers while also being compliant with safety standards set forth by regulatory bodies.

Other choices represent different ratios that do not meet the established safety guidelines for odorization, thus making them unsuitable for ensuring adequate detection of gas leaks.
