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

The correct ratio of Ethyl Mercaptan in 10,000 gallons of LP Gas is established based on industry standards for odorization of propane. Ethyl Mercaptan is added to propane to give it a distinct smell, which is crucial for safety as propane is otherwise odorless.

For 10,000 gallons of LP Gas, the generally accepted standard is to use approximately 1 pound of Ethyl Mercaptan. This ratio ensures that the propane has a detectable odor at concentrations that are safe and effective for leak detection. This critical aspect of propane safety helps to alarm individuals in the event of any leaks, preventing dangerous situations.

The other ratios suggested would either be too low or too high in comparison to the standard used in the industry. A lower amount may not produce a sufficient odor for effective leak detection, while larger amounts could lead to excessive odors that might become unpleasant and could even mask the smell with strong, overpowering scents. Thus, the 1 lb. standard effectively balances safety and practicality.
