Propane - C3H8
This page presents information on propane (C3H8) or dimethylmethane, appropriate detection means - Propane gas detector - and proper respiratory protective equipment (self-contained breathing apparatus and supplied air respirator).
Propane properties (C3H8)
Propane (C4H8) or dimethylmethane is an alkane that is mainly used as a combustion energy source in internal combustion engines or boilers. It is primarily released from natural gas purification or liquefied petroleum gases separation. Propane is industrially used as a reactive agent for synthesis of ethylene, benzene, toluene or xylene.

Propane effects on heath
When pure, propane (C3H8) is a colorless and odorless gas. Ethanethiol – an odorant – is added to easily detect any gas leak. Propane is harmful by inhalation and causes oxygen depletion (with suffocation risk). It can be found gaseous at ambient temperature but it also can liquefy under a pressure around 10 bars. Its combustion is clean and generates water and carbonic gas.
Propane gas detector - C3H8
As it is not always detectable through smell, only a propane gas monitor can accurately measure concentrations of this combustible gas. It is recommended to use propane detection systems that monitor the explosive concentration potential with measurements in percentage of the LEL (explosimeter).
For calibration and gas testing of your fixed or portable gas detectors, propane calibration gas cylinders are available.
C3H8 respiratory protection - Propane
As propane is an asphyxiating gas featuring important risks of suffocation, it is advised to wear and open circuit self-contained breathing apparatus (SCBA) or an supplied air respirator for long-term interventions.
