What should the discharge location be to enhance safety during indoor purging?

To enhance safety during indoor purging, the correct choice is to discharge through an appliance burner with a constant ignition source. This method helps ensure that any purged gas is immediately ignited and burned off, minimizing the risk of gas accumulation in the indoor environment. By using an appliance burner designed for this purpose, it effectively controls and eliminates any potentially hazardous gas release during the purging process, thereby reducing the likelihood of an explosion or fire.

Discharging in a ventilated area may seem reasonable as it allows for some of the gas to dissipate, but if the gas is not ignited immediately, it can still pose a significant risk. Similarly, while a discharge near a window could help some gas escape, it does not offer the same level of safety as directly combusting the gas at an ignition source. Choosing to discharge in the kitchen area without the use of a controlled ignition source can lead to uncontained gas exposure, posing serious safety hazards.
