General information about LPG
Characteristics of LPG
| Hazardous and extremely flammable. |
 |
- Colorless, odorless, non toxic, therefore additives, usually ethyl mercaptan, are added to create odorants which helps know when there is gas leakage.
- Exposure to high concentration can lead to headache, dizziness, nausea... |
  |
| Vapor at normal temperature. High compression is applied to change gaseous status into liquid. Storable and transportable |
 |
| Expansion of some 250 times when converted from liquid to gaseous status, liquid leakage must be strictly controlled. Cylinders must be uppermost |
 |
| Heavier than air at gaseous status and lighter than water at as liquid. Always placing cyliners far away from drainages, holes... |
|
- Expansion of 15 times higher than water as temperature up. Therefore, filling at max 85% and keeping cylinders away from heat.
- Combustible mixture is formed only if the gas/air ratio is 1.8% to 9.3% concentration

Potential risks to result in fires & explosions
Three factors are required in proper combination before fire and explosive combustion can take place: fuel-gas, ignition
and oxygen
1. Fuel-gas to burn.
2. Air to supply oxygen.
3. Ignition source to start and continue the combustion process.
In which 02 factors (fuels and Ignition sources are controllable)
