Does a mixed gas containing a small amount of flammable components have an explosion limit? Is it necessary to divide the explosion area?

I have a question for all the experts here: there is a type of waste gas that contains 1% hydrogen, 1% carbon monoxide, 0.5% methane, and 97.5% nitrogen. By calculating it as a mixed gas, it should be possible to determine the explosion limit of this gas (a%~b%). But based on personal judgment, the concentrations of these three gases are all below their respective lower explosion limits; therefore, this gas in the air, no matter what its concentration, should not be able to catch fire. So, does a place containing this gas need to be classified as a site with explosion hazards? ?
