Propane and butane gas, like natural gas, have no odor. A powerful, foul-smelling chemical is introduced to the gas to detect any leakage.

What is added to butane to make it smell?

Butane and propane (see: LPG) are purposefully laced with ethanethiol to give them a distinct odor. These ordinarily odorless fuels represent a risk of fire, explosion, and asphyxiation.

Ethanethiol, also known as ethyl mercaptan, is referred to as “stench gas” in the underground mining sector.

During an emergency, the gas is released into mine ventilation systems to inform mine personnel.

“The alarm system in an underground mine shall consist of the introduction into all workplaces of sufficient volumes of ethyl mercaptan gas or comparable gas to be readily identifiable by all workers,” according to Ontario mining legislation.

Can inhaling butane harm you?


Does butane smell like propane?

Liquid petroleum gas (LPG) is a blend of propane and butane. These gases, like methane, are hydrocarbons, although they’re a little more complicated. Butane has four carbon atoms and ten hydrogen atoms, whereas propane has three carbon atoms and eight hydrogen atoms.

What else smells like propane?

Propane has an offensive odor similar to rotten eggs, skunk spray, or a dead animal. Gas makers intentionally add the odor to help customers detect propane leaks, which can be dangerous. If you suspect you’ve detected this terrible stench, act immediately.

Make sure you’re not smelling rubbish, sewage, skunk spray, or a dead animal if you think you’re smelling propane.

It’s possible that a slight propane odor isn’t reason for concern. When starting a stove, or when the pilot light in a gas fireplace, hot water heater, or other equipment goes out, it’s common for a propane stench to linger.

While any potential leak should be taken carefully, be extra cautious if the odor is unusually strong, persistent, or accompanied by a hissing sound.
