Here's why:
* Odorization: Natural gas is naturally odorless and colorless. This poses a safety hazard, as leaks can go undetected. Mercaptan has a strong, unpleasant odor (similar to rotten eggs) that serves as a warning signal, alerting people to gas leaks.
* Early Detection: The odor of mercaptan allows for the detection of leaks even at low concentrations, ensuring prompt action to prevent potential fires or explosions.
Important Note: The amount of mercaptan added is carefully controlled to ensure a strong, noticeable odor while remaining safe for human health.
