Subtitle: Flammable Gases
Flammable gases are gases that can ignite when exposed to a source of ignition, such as heat, sparks, or flames. Some of the most common flammable gases include natural gas, propane, butane, acetylene, methane, ethylene, and hydrogen. These gases are highly combustible and can cause serious damage if not handled and stored properly.
Ignition Source: An ignition source is any device or material that can cause a fire. Common ignition sources include heat, sparks, flames, and static electricity. All of these sources can cause an explosion or fire if a flammable gas is present.
Flash Point: The flash point of a flammable gas is the temperature at which it will burn if exposed to an ignition source. Most flammable gases have a flash point of around 500°F (260°C).
Explosive Range: The explosive range is the range of concentrations in which a fuel-air mixture will ignite and burn. For example, if the concentration of a flammable gas is between its lower and upper explosive limits, then a spark or a flame can cause an explosion.
Lower Explosive Limit (LEL): The lower explosive limit (LEL) is the lowest concentration of a flammable gas in the air that will cause an explosion or fire.
Upper Explosive Limit (UEL): The upper explosive limit (UEL) is the highest concentration of a flammable gas in the air that will cause an explosion or fire.
Flammable Limits: The flammable limits are the range of concentrations in which a flammable gas is capable of burning. The lower flammable limit (LFL) is the concentration at which a gas can ignite and burn. The upper flammable limit (UFL) is the concentration at which a gas can no longer burn.
It is important to understand the properties of flammable gases and the risks associated with them. All flammable gases should be handled and stored properly in order to prevent fires and explosions.
