What must be done with outlets that are not to be used immediately after an appliance is disconnected?

Leave them open
Seal them with a cap or plug gastight
Label them for future use
Angle the pipe upwards

The correct answer is: Seal them with a cap or plug gastight

Sealing outlets that are not going to be used immediately after an appliance is disconnected is essential for ensuring safety and preventing gas leaks. When you seal them with a cap or plug that is gastight, you eliminate the risk of gas escaping from the outlet, which could lead to hazardous situations such as fire or explosion. This practice is particularly important in maintaining a safe working environment and complying with safety regulations. Leaving the outlets open or simply labeling them for future use does not mitigate the risk posed by potential leaks, as open outlets can allow gas to escape into the environment. Additionally, angling the pipe upwards is not a standard practice for managing unused outlets and does not provide an effective seal against gas leaks. Sealing unused gas outlets with gastight caps or plugs is a proactive safety measure that ensures no gas can inadvertently escape, protecting individuals and property from potential hazards.
