Propane is denser than air. If a leak in a propane fuel system occurs, the vaporized gas will have a tendency to sink into any enclosed area and thus poses a risk of explosion and fire. The typical scenario is a leaking cylinder stored in a basement; the propane leak drifts across the floor to the pilot light on the furnace or water heater, and ...
LPG in its gaseous phase is still heavier than air, unlike natural gas, and thus will flow along floors and tend to settle in low spots, such as basements. There are two main dangers to this. The first is a possible explosion if the mixture of LPG and air is within the explosive limits and there is an ignition source. The second is suffocation ...
A lifting gas or lighter-than-air gas is a gas that has a density lower than normal atmospheric gases and rises above them as a result, making it useful in lifting lighter-than-air aircraft. Only certain lighter than air gases are suitable as lifting gases. Dry air has a density of about 1.29 g/L (gram per liter) at standard conditions for ...
Propane does not have health effects other than the danger of frostbite or asphyxiation. The National Propane Gas Association has a generic MSDS available online ...
Toxic: a chemical that has a median lethal concentration (LC 50) in air of more than 200 parts per million (ppm) but not more than 2,000 parts per million by volume of gas or vapor, or more than 2 milligrams per liter but not more than 20 milligrams per liter of mist, fume or dust, when administered by continuous inhalation for 1 hour (or less if death occurs within 1 hour) to albino rats ...

Natural gas compounds with more than two carbon atoms exist as liquids at ambient temperatures and pressures. [4] Propane, butane, and isobutane are liquid at normal temperatures only under pressure. Additionally, condensate may contain: [5] [6] [7] Heavier straight-chain alkanes having from 7 to 12 carbon atoms (denoted as C 7 to C 12 ...
A detector for propane is best placed down low near the floor, as propane is heavier than air. [3] A detector for natural gas (city gas) is best placed up high, near the ceiling. [3] Some detectors can detect both natural gas or propane, but this requires a compromise location. [4]
