Methane Gas – General Information
Methane gas comes from the earth and it comes from our bodies. Methane is non-toxic and it can be
harnessed as an energy source. However, methane is highly explosive and it can cause death by
asphyxiation. It is important to understand how to deal with the hazards associated with methane.
Although methane on its own isn't poisonous, it has the potential to become poisonous when mixed with
other substances. That potential exists when natural gas (CH
houses, offices and businesses. The burning of natural gas without proper ventilation can produce carbon
monoxide, a deadly gas that is difficult to detect.
SYMPTOMS OF METHANE GAS EXPOSURE
Methane gas is relatively non-toxic and associated with being a simple asphyxiator displacing oxygen in
the lungs. However Methane is extremely combustible.
Exposure to high levels of Methane can cause:
Suffocation

Loss of consciousness

Headache and dizziness

Nausea and vomiting

Weakness

Loss of co-ordination

Increased breathing rate

METHANE GAS LEVELS - %
The LEL (Lower Explosive Limit) of methane is considered to be 5% BV (by volume of air).
So we call 5% BV (by volume) the same as 100% of the LEL (Lower Explosion Limit).
Your device is equipped with a digital display that shows the level of natural gas in the area referred to as
LEL% (a percentage of the LEL) and will alarm based on the following principle of gas detection.
In simplified terms, a level of 8% LEL or less on your device is generally considered safe and acceptable.
