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

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


He replied to "They refused to tell me the

It is still quoted above.
