What else can I help you with?
Can carbon monoxide explode?
No, carbon monoxide itself cannot explode. However, it is highly flammable and can contribute to fires or explosions if ignited in the presence of oxygen. It is important to keep carbon monoxide levels low to prevent any potential fire hazards.
What is upper explosive limit?
The upper explosive limit (UEL) is the maximum concentration of a gas or vapor in air above which it cannot ignite or explode. This means that if the concentration of the gas exceeds the UEL, there is not enough oxygen present for combustion to occur. It is important to stay below the UEL when working with flammable substances to prevent explosions.
What is Natural gas flash point?
The flash point of natural gas is typically not defined in the traditional sense, as natural gas is a mixture primarily composed of methane, which has a very low flash point of around -188°C (-306°F). This means it can ignite at very low temperatures when mixed with air. However, in practical applications, natural gas is usually handled in its gaseous state, making flash point considerations less relevant compared to liquid fuels. Instead, its lower explosive limit (LEL) and upper explosive limit (UEL) are more critical for safety assessments.
What temperature can gasoline still give off flammable vapor?
The FR (flammable range) of gasoline is 1.4% LEL (lower exposive limit) to 7.6 UEL (upper exposive limit). Below 1.4% the gasoline vapor is said to be too lean and above 7.6% and the vapor is too rich. In either case gasoline will not burn if it is not in the FR.
Will flammable gas concentration above the upper explosive limit burn?
No, flammable gas concentrations above the upper explosive limit (UEL) are too rich to ignite and burn. In order for a flammable gas to ignite, it needs to be within its flammable range, which lies between the lower and upper explosive limits. Concentrations outside this range will not burn.
What is lel uel?
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.
What is UEL?
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.
What is the difference between LEL and UEL?
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.
What is the Percentage range of lel and uel for natural gas?
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
What is the differrence between lel and uel?
LEL (Lower Explosive Limit) is the minimum concentration of a gas or vapor in air below which it will not ignite, while UEL (Upper Explosive Limit) is the maximum concentration above which it will not ignite. These limits are important for assessing the fire and explosion risks of gases and vapors in various settings.

What are some interview questions about fire and safety in refineries?
all about fire..About classification of fire, about methods of extinguising & transmission of heat,about extinguishing medias...about MSDS also & they require good knowledge about gases(TLV,PPM,LEL,UEL,PEL)of gases etc.
