What is a common hazard when working with gas piping that must be taken into account?

A common hazard when working with gas piping is the risk of fire and explosion. This is primarily due to the highly flammable nature of natural gas and propane, which can create an explosive atmosphere if leaks occur. Gas must be handled with extreme care; any small leak can lead to serious safety issues, such as igniting from an open flame or spark, which can result in severe injuries, property damage, or even loss of life. Proper safety protocols, including leak detection, proper ventilation, and use of appropriate tools and materials, are essential to mitigate this risk when installing or repairing gas piping systems.

While electric shock, water damage, and injury from heavy lifting are important hazards to consider in other contexts, they are not specific to the risks associated with gas piping. The emphasis on fire and explosion highlights the critical importance of understanding the nature of gases and the potential consequences of mishandling them in a working environment.
