Ethyl Mercaptan is used as the odourant which allows the LPG vapour to be smelt.
It results in a slight smell similar to rotten cabbages so as to alert one of leaks at a level way below its Lower Explosive Limit (LEL).
The lower & upper levels are tabled below & explain why LPG is so dangerous since the range is quite low being only 1.7% to 10.9%

Colourless and odourless and an asphyxiante so particular care needs to be taken with this gas.
This naturally means a room with a few percent of LPG together with an ignition source would be an extremely dangerous situation to enter.
Ethyl mercaptan is added to LPG as an an odourant so that generally it can be smelt if leaking. The smell is however subtle & often not immediately detected by users of the gas.
Most users of the gas describe the smell as smelling like either rotten eggs or rotten cabbage.
At a density of 1.9 kg/m3 (1.58 relative to air at normal atmospheric conditions) it is markedly denser than air so it is potentially extremely dangerous in low points and this aspect has resulted in some spectacular incidents in still cold air.

Hazards
As mentioned in the Product Overview, LPG is highly flammable as well as heavier than air making it a higher risk for fire hazards where ther are pits or low lying area.

Variations in the dimensions and weight of the cylinder can be expected due to manufacturing tolerances. The weight and the pressure of the gas-filled will be as specified.
The volume and the pressure of the contained gas in the cylinders will be as specified in the above table.
CYLINDER HANDLING AND STORAGE
or close a cylinder valve (Clockwise looking down at the hand wheel, directional arrows are on the hand wheel.)
by hand using moderate torque to open or close them. Too much closing torque can damage the cylinder valve seat.
Only use set spanners or specific tools that are provided by the cylinder supplier to connect accessories.
Multi-grips should never be used.
Some regulators require a sealing washer in or on the inlet spigot.
Check that this is present before fitting the regulator to the cylinder valve outlet
Handling leaks
