They refused to tell me the
concentrations of various impurities normally found in natural gas.

I imagine they could do that years ago. Today, just ask for an MSDS
sheet. They have them and will send it to you.

Google is your friend

Natural gas is not the same as propane.


No ****, that is why I posted the MSDS for natural gas.

Natural Gas Material Safety Data Sheet


This is propane

INGREDIENT NAME /CAS NUMBER PERCENTAGE OSHA PEL ACGIH TLV
Propane / 74-98-6 .…………………………………........87.5 -100 Simple asphyxiant
Ethane / 74-84-0 .…………………………………………. 0 - 7.0 1, Simple asphyxiant
Propylene / 115-07-1 ……………………………………... 0 - 5.0 Simple asphyxiant
Butanes / 106-97-8 …….…………………………………. 0 - 2.5 Simple asphyxiant
Ethyl Mercaptan / 75-08-1……………………………….. 0 - 50 ppm 0.5 ppm 0.5 ppm


the thread TITLE is ".....propane stoves",so why post about natural gas?
