The range between the lel and uel is known as the flammable range for that. If a mixture is at or above 100% lel and has. As a rule of thumb, alarm set points should be set conservatively to allow for inaccuracies and unknown conditions. Web the minimum concentration of a particular combustible gas or vapor necessary to support its combustion in air is defined as the lower explosive limit (lel) for that gas. This threshold is the safe limit for up to 100% lel of nearly all chemicals, but it depends on the combustible gas concentration. Web rae systems by honeywell.
