Which factor increases the risk of gas leaks?

The factor that increases the risk of gas leaks is poor gas line installation. When gas lines are not installed correctly, it can lead to numerous issues such as improper sealing, inadequate connections, or misalignment of pipes. These mistakes create weak points in the gas distribution system where leaks can occur. Factors such as using pipes that are not suited for gas service, failing to use proper fittings, or inadequate support for the gas lines can all contribute to an increased risk of gas escaping.

In contrast, properly installed gas lines, regular inspections, and the use of high-quality materials all serve to minimize the chances of leaks. Proper installation ensures that connections are secure and compliant with safety codes, while regular inspections help identify potential issues before they lead to leaks. High-quality materials are less likely to degrade over time, reducing the risk of leaks developing due to wear and tear.
