Difference between Flammable and Highly Flammable

Difference between Flammable and Highly Flammable

In order to stay safe around fires, it is important to understand the difference between flammable and highly flammable materials. Flammable materials are easily ignited and can quickly spread fire, while highly flammable materials are even more combustible than flammable materials. It is crucial to know which substances are which in order to take the necessary precautions when working with or near flames. For example, while gasoline is considered a flammable liquid, methane gas is considered a highly flammable gas.

What is Flammable?

  • Flammability is the ability of a substance to catch fire and burn. The Flammable limit is the minimum concentration of vapor in the air at which ignition will occur. The Lower Flammable Limit (LFL) is the lowest concentration of vapor in air at which propagation of flame will occur on contact with a heated surface. The Upper Flammable Limit (UFL) is the highest concentration of vapor in air at which propagation of flame will occur on contact with a heated surface.
  • Flammability is affected by many factors including oxygen content, heat, sparks, static electricity, and chemicals. Flammable liquids are those that can be easily set on fire and burnt. These are usually liquids with a low flash point, such as gasoline, ethanol, and acetone. Flammable solids are those that can be easily set on fire and burnt.
  • These include materials that are easily ignited and burn rapidly, such as magnesium and fireworks. Flammable gases are those that can be easily set on fire and burnt. These include gases that are easily ignited and burn rapidly, such as hydrogen and propane.

What is Highly Flammable?

Highly flammable materials are substances that can easily catch fire and burn rapidly. They are usually chemicals that are volatile, meaning they evaporate easily at room temperature. Highly flammable liquids, such as gasoline, alcohol, and acetone, are often used as solvents or cleaning agents. Highly flammable gases, such as propane and methane, are often used as fuel. Highly flammable solids, such as magnesium and charcoal, can also be used as fuel. Highly flammable materials can be extremely dangerous if they are not handled properly. They should always be stored in a cool, dry place away from heat or sparks.

Difference between Flammable and Highly Flammable

Flammable and highly flammable liquids are significant fire hazards in the workplace. Flammable liquids have a flash point below 100 degrees Fahrenheit, while highly flammable liquids have a flash point below 75 degrees Fahrenheit. Both types of liquids are easily ignited and can quickly lead to a dangerous fire. For this reason, it is important to handle flammable and highly flammable liquids with care.

When storing these liquids, be sure to keep them in cool, well-ventilated areas away from heat sources. In addition, always use appropriate safety equipment when handling flammable liquids, such as gloves and eyewear. By taking these precautions, you can help to prevent a potentially catastrophic fire in the workplace.

Conclusion

The difference between flammable and highly flammable liquids is important to understand. Flammable liquids will ignite when in contact with an open flame, while highly flammable liquids have a much higher chance of igniting and burning more intensely. Understanding the difference can help you prevent dangerous accidents in the workplace or at home. Always read labels carefully and store flammable and highly flammable liquids properly in approved containers.
