3. Vapor pressure

The explosive range of LPG is 1.8% to 9.5% of the gas volume in air. This is much narrower than other common gaseous fuels. This points to the danger of LPG vapors accumulating in low-lying areas in the event of a leak or spill. The autoignition temperature of liquefied petroleum gas is about 410-580°C. C, so it will not spontaneously ignite at room temperature.

Air trapped in the vapor during pumping/filling operations is hazardous to unpurged containers/cylinders. For this reason, the use of air pressure to unload LPG cargoes or tankers is not recommended.

4. to burn

The combustion reaction of LPG increases the volume of the product in addition to generating heat. LPG requires up to 50 times its volume in air to burn completely. Therefore, when LPG is burned in an enclosed space, adequate ventilation must be provided, otherwise, in addition to the formation of carbon dioxide, suffocation will result from depletion of oxygen.

5. Smell

LPG has only a very faint smell, so some odorant needs to be added so that any escaping gas can be easily detected.

For this purpose, ethanethiol is generally used as odorant. Addition should be sufficient to allow 1/5 of the lower flammability limit or odor class 2 (according to IS: 4576) to be detected in the atmosphere.

6. Color

Liquefied petroleum gas is colorless in both liquid and gaseous phases. During the leak, the evaporation of the liquid cools the atmosphere and condenses the water vapor it contains, forming a white mist that makes the escaping LPG visible.

7. Toxicity

Although slightly toxic, liquefied petroleum gas is non-toxic in the gas phase, but may cause suffocation by displacing oxygen at high concentrations. For this reason, the vapor has mild anesthetic properties.
