The black line represents the theoretical lower explosive limit
(LEL) of different fuels.
m] is the lower explosive limit
of the gas mixture considering the inert gas, %; [U.
In addition, the vapor could be toxic enough to be fatal but not flammable enough to cause an alarm beyond the 10% lower explosive limit
or enough of it by volume to displace the oxygen to the 19.
Ammonia's lower explosive limit
(LEL) is 15% to 16% in air, five to 10 times the LEL concentration of common flammable gases.
The lower explosive limit
of methane has been known to be about 5% since the early 19th century.
Users can select from over 20 sensors for toxic and combustible gases at the lower explosive limit
(LEL), oxygen, and a photoionization detector (PID) that monitors volatile organic compounds (VOCs) at parts per million levels for quick, accurate response.
a) A combustible gas in a distribution line must contain a natural odorant or be odorized so that at a concentration in air of one-fifth of the lower explosive limit
, the gas is readily detectable by a person with a normal sense of smell.
FITCHBURG - A woman known as the "bird lady," and her menagerie of exotic pets, is safe after a gas leak that caused levels to register 7 percent above the lower explosive limit
in an East Street home yesterday morning.
C/926 has test data that shows the PhD ultra CO and H2S sensors will not work properly in the submarine atmosphere due to the hydrogen background, the data also shows that the oxygen and Lower Explosive Limit
(LEL) sensors will work properly aboard a submarine.
Very simply, because of small access areas to fuel cells, such as those found on some aircraft where a person cannot enter the cell with the exception of his or her arms and hands, only lower explosive limit
(LEL) checks are required in accordance with NA-01-35.
5%, (2) toxic chemical exposure exceeds any OSHA permissible exposure limit (PEL), or (3) flammable vapors exceed 10% of the lower explosive limit
