Lower explosion limit of common combustible gas:

NO.	GAS	LEL	NO.	GAS	LEL
1	Hydrogen(H2)	4.0%VOL	7	Methane(CH4)	5.0%VOL
2	Ethyne(C2H2)	2.5%VOL	8	Methylbenzene(C7H8)	1.1%VOL
3	Benzene(C6H6)	1.2%VOL	9	Ethanol(C2H6O)	3.3%VOL
4	Butane(C4H10)	1.9%VOL	10	Methanol(CH3OH)	6.0%VOL
5	Propane(C3H8)	2.1%VOL	11	Dimethylbenzene(C8H10)	1.1%VOL
6	Ethane(C2H6)	3.0%VOL	12	Ethylene(C2H4)	2.7%VOL

e.g: CH4 (5%VOL=100%LEL),When the methane concentration reaches 5% VOL, it reaches its lower limit of explosion.
