Depends what the constituent of the natural gas is. It will more than likely be methane, which LFL is 5 and UFL is 15. Here is a list of some flammability limits in the link below.

Can oxygen be dangerous?
Yes. Oxygen is needed for flammable objects to burn. In increased concentrations oxygen will cause flammable materials to burn faster, and more intensely and allows them to ignite at lower temperatures.
What is the difference between hazardous and flammable gas?
Capable of igniting and burning is a combustible gas. Any compressed gas meeting the requirements for lower flammability limit, flammability limit range, flame projection,etc. All flammable substances are surely combustible, but all combustible substances are not essentially flammable.
What has to happen for a gas or vapor to be flammable or an explosion hazard?
For a gas or vapor to be flammable or an explosion hazard it must have a concentration in air between the Lower Explosive Limit (LEL) and the Upper Explosive Limit (UEL) for that particular gas or vapor.
What is the difference between flammable and combustible material?
A flammable material has a lower flash point (100F or below) while a combustible material has a flash point of 100F or HIGHER. In other words, it's a lot easier for a flammable material to catch fire than a combustible one because of the minimal amount of energy (heat) required to get it going versus the higher requirement of a combustible material.
Which fractions will ignite more easily short carbon chains or long carbon chains?
Fractions that boil at lower temperatures are known as 'highly flammable. They are used as: Liquefied Petroleum Gas Chemicals Petrol for vehicles
What temperature can gasoline still give off flammable vapor?
The FR (flammable range) of gasoline is 1.4% LEL (lower exposive limit) to 7.6 UEL (upper exposive limit). Below 1.4% the gasoline vapor is said to be too lean and above 7.6% and the vapor is too rich. In either case gasoline will not burn if it is not in the FR.
What is UEL?
All of natural gas has LEL which means lower explosive limit and UEL upper explosive limits mean if lower or upper value for any gas found you get explosion.
What is lel uel?
All of natural gas has LEL which means lower explosive limit and UEL upper explosive limits mean if lower or upper value for any gas found you get explosion.
What are the advantages and disadvantages of natural gas as an energy source?
Natural gas has many advantages but one of them is, It produces big amounts of energy, but lower levels of many air pollutants that coal or oil. One disadvantage of natural gas is that it is highly flammable. Hope I helped!
Does the midpoint of a frequency distribution class equal the sum of the lower and upper limits?
No, the midpoint is the result of adding the upper and lower limits in a class and dividing that by 2. Essentially the mid point is the average of the two limits.
What is class limit according to statistics?
The lower and upper limits of a class interval are known as Class Limits.
Whats The difference between a 6 and 7 string guitar?
There is practically no difference. The 7-string guitar has one lower string that the 6-string does not. It is usually tuned to B(natural).
Why does petrol catches fire easily?
Because petrol is highly flammable and it has lower flash point
How do you lower your kidney enzymes with a natural food?
how do you lower kidney enzymes with a natural food?
What are limits and why you use them?
Limits give upper and lower bounds for integration. One simple example is in finding an enclosed area. The upper and lower limits form vertical lines which enclose an area between the function and the x-axis and then integration from the lower limit (smaller x boundary) to the upper limit (larger x boundary).
Can oxygen be dangerous?
Yes. Oxygen is needed for flammable objects to burn. In increased concentrations oxygen will cause flammable materials to burn faster, and more intensely and allows them to ignite at lower temperatures.
Show that the line integral is independent of the path?
since the line integral depends on the two values upper & lower limits and the function to which we have to integrate. the values changes only when the upper & lower limits changes, whatever the path is.
