Do you really expect anyone to quote the entire NFPA 54? on here?
The color code for natural gas pipelines is typically yellow. This color is used to indicate that caution should be taken in the area due to the presence of natural gas lines. It's important to always verify specific color codes with the relevant regulations or guidelines in your area.
Natural gas sould be transfered in yellow pipes.
Yes. But, only if the union is after a main shut off valve and is before and appliance connection. ex. A ball valve then pipe and a union before an furnace connection. Unions used as couplings to lengthen pipe are not code approved.
Thawing natural gas lines should only be done by a professional. Methods may include applying heat or steam using specialized equipment to slowly and safely unthaw the frozen lines. It is important to avoid using open flames or other risky methods that could lead to gas leaks or fires.
No, natural gas and propane orifices are not interchangeable. Natural gas orifices are larger than propane orifices due to the different properties of the gases. Using a propane orifice with natural gas can lead to incomplete combustion and potential safety hazards.
OSHA has not established color code requirements for natural gas lines.

Gas company lines primarily transport natural gas, not oxygen. Natural gas is a fossil fuel composed mainly of methane. Oxygen is not typically present inside gas company lines as it is not used in natural gas transportation.
No just make sure it follows all local laws.
natural gas?
pipe lines and stoves
Yes. But, only if the union is after a main shut off valve and is before and appliance connection. ex. A ball valve then pipe and a union before an furnace connection. Unions used as couplings to lengthen pipe are not code approved.
It depend on how cold it gets in the basement.
What does your local code say
211112 (Natural Gas Liquid Extraction)
yes. Generally caused by ruptured natural gas lines.
