| Propane (C3H8) |
| Propane is a single-component liquefied fuel gas used for oxy-fuel gas cutting, heating, brazing, and soldering. The main source of this gas is the crude-oil and gas mixtures obtained from active oil and natural gas wells. It is also produced in certain oil refining processes and in the recycling of natural gas. It is sold and transported in steel cylinders of various sizes and is available in bulk. |
| Safety
Propane is nontoxic and has narrow explosive limits in air. Short exposure to propane vapor is not harmful; although, high concentrations may produce a slight anesthetic effect. Avoid contact with the liquid since it could cause frostbite-type burns. |
