South Carolina LP Gas Reseller Practice Exam - Prep & Study Guide

Propane gas is intentionally odorized with a substance called mercaptan, which gives it a distinct and unpleasant smell that resembles rotten eggs. This odor is crucial for safety because propane is an odorless gas in its natural state. The addition of this recognizable scent allows individuals to detect gas leaks quickly, which is vital for preventing potential hazards such as fires or explosions. Because of this safety measure, the characteristic smell serves as an early warning system, enabling people to evacuate the area and address the situation without delay.

The other options, such as lavender, mint, or cherry, do not relate to the actual smell of propane and are not used in the odorization process, which is why they do not fit in this context.
