A common hazard associated with gas line installations is gas leaks. Gas leaks can pose significant risks, including potential explosions or fires if the gas ignites. They can result from various factors, such as improper installation, damaged pipes, or faulty fittings. Gas is odorless in its natural state, but an odorant (typically mercaptan) is added to detect leaks; the presence of this odor is a critical warning sign. Understanding the importance of proper sealing, regular inspections, and maintenance can help minimize the risk of gas leaks during installations.

Corrosion of the pipes is a concern in gas system longevity and can lead to leaks over time, but it is not as immediate of a hazard as a gas leak itself. Insufficient pressure can lead to poor appliance performance or inefficient operation, while over-ventilation is not a major hazard associated with gas line installations. Therefore, recognizing gas leaks as a primary hazard is crucial for safety in gas fitting.
