The Lower Explosive Limit (LEL) of natural gas (which is primarily methane). is 5% by volume in air.
The Upper Explosive Limit (UEL) is 15% by volume in air
100% LEL is 5 %. So 10 % of it is 0.5%

As per Osha, in a confined space, less than 10 percent LEL is considered safe

The short version:Gabriel is the Messenger of God, Michael is an Archangel and Abaddon( Apollyon) is the angel of bottomless pit. Satan and Lucifer (the anointed cherub) are of the fallen angels.The long version (links included):Gabriel speaks to Mary in Luke 1:19, is given an order in Daniel 8:16, and makes physical contact with someone in Daniel 9:21 http://en.wikipedia.org/wiki/GabrielMichael is seen in Daniel's vision. Daniel 10:13, 21, and Daniel 12:1 directly names Michael.In Jude 9 he is called Michael the archangel.http://en.wikipedia.org/wikiMichael_(archangel)Revelation 9:11 speaks of an angel of the bottomless pit named "Apollyon" in Greek and "Abaddon" in Hebrew.http://www.blueletterbible.org/Bible.cfm?b=Rev&c=9&v=11&t=KJV#11Satan is commonly held to be an angel who was cast down from heaven with approximately 1/3 the host of heaven.http://en.wikipedia.org/wiki/SatanLucifer (Hebrew: Hel-lel, 'shining one') is found in Isaiah 14:12 (KJV). However the context shows that Isaiah, in verse 14, is actually referring to the King of Babylon (See Isaiah 14:4).http://en.wikipedia.org/wiki/Lucifer#The_Morning_Star_in_Isaiah_14:12------------------There appear to be no Bible verses where Wisdom, Peace, Hope, and Justice are personified as angels. Angels in biblical scripture do tend to bring wisdom, peace, hope, and justice, but these are rarely their sole function.------------------So there seems to be four angels specifically named in the KJV:Satan (also called the Devil),MichaelGabrielApollyon/Abaddon.In addition to specifically named angels, and 'angels' in general, the Bible also names special types of angels, such as cherubs -'cherubim', Genesis 3:24, and seraphs-'seraphim', Isaiah 6:2.

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.

NO, you cannot at present use a hydrocarbon gas detector which generally use IR absorption technology to detect hydrogen.
What is a LEL mete
LEL is the Lower Explosive Limit. The lowest ignitable concentration of a substance in air that will ignite. UEL is the Upper Explosive Limit. The highest percentage of a substance in air that will ignite.
The lel of alcohol is 3.3% - 10% lel - 3300 ppm idlh 15000 ppm
The exposure limit to Lower Explosive Limit (LEL) varies depending on the specific substance. It is usually expressed as a percentage of the gas or vapor in the air concentration that presents a potential explosion hazard. It is important to refer to the Material Safety Data Sheet (MSDS) or other relevant safety guidelines for specific exposure limits for different substances.
