Extremely Flammable vs. Highly Flammable
What's the Difference?
Extremely flammable and highly flammable are both classifications used to describe materials that are prone to catching fire easily. However, the key difference between the two is the degree of risk associated with each classification. Extremely flammable materials are considered to be even more volatile and dangerous than highly flammable materials, meaning they have a higher likelihood of igniting and spreading rapidly. Both classifications require careful handling and storage to prevent accidents and ensure safety in any environment.
Comparison
| Attribute | Extremely Flammable | Highly Flammable |
|---|---|---|
| Definition | Capable of igniting easily and burning rapidly | Capable of igniting easily and burning rapidly |
| Flash Point | Below 0°C | Below 21°C |
| Ignition Temperature | Lower than Highly Flammable | Higher than Extremely Flammable |
| Examples | Hydrogen, acetylene | Gasoline, ethanol |
Further Detail
Definition
Extremely flammable and highly flammable are terms used to describe materials that are easily ignited and can quickly spread fire. The difference between the two lies in the degree of flammability. Extremely flammable materials ignite at lower temperatures and burn more rapidly than highly flammable materials.
Ignition Temperature
One key difference between extremely flammable and highly flammable materials is their ignition temperature. Extremely flammable materials have a lower ignition temperature, meaning they can ignite at lower temperatures compared to highly flammable materials. This makes extremely flammable materials more dangerous in terms of fire risk.
Burning Rate
Another important attribute to consider when comparing extremely flammable and highly flammable materials is their burning rate. Extremely flammable materials burn at a faster rate than highly flammable materials. This means that fires involving extremely flammable materials can spread more quickly and be harder to control.
Volatility
Volatility refers to how easily a substance vaporizes into the air. Extremely flammable materials are more volatile than highly flammable materials, which means they can easily form flammable vapors that can ignite and cause fires. This makes extremely flammable materials more hazardous in terms of fire safety.
Flash Point
The flash point of a material is the temperature at which it gives off enough vapor to ignite in the presence of an ignition source. Extremely flammable materials have a lower flash point compared to highly flammable materials. This means that extremely flammable materials are more likely to ignite and cause fires at lower temperatures.
Regulations
Due to the higher risk associated with extremely flammable materials, there are stricter regulations in place for handling and storing these materials compared to highly flammable materials. Companies that deal with extremely flammable materials are required to follow specific safety protocols to minimize the risk of fires and accidents.
Examples
Examples of extremely flammable materials include hydrogen, acetylene, and propane. These materials are highly reactive and can ignite easily, posing a significant fire hazard. On the other hand, examples of highly flammable materials include gasoline, ethanol, and diesel fuel. While these materials are also flammable, they are less reactive and ignite at higher temperatures compared to extremely flammable materials.
Conclusion
In conclusion, the attributes of extremely flammable and highly flammable materials differ in terms of ignition temperature, burning rate, volatility, flash point, and regulations. Extremely flammable materials are more dangerous and pose a higher fire risk compared to highly flammable materials. It is important to handle and store these materials with caution to prevent accidents and ensure fire safety.
