What’s the difference between Flammables and Combustibles?

And why should you care? Well if you store anything in your basement or garage, you should know the difference and you should be careful of how you store them.

One of the major confusion people will have is about flammables and combustibles. First let’s talk about flammables.

What’s the difference between Flammables and Combustibles

Flammables- these are the substances which catches fire. And flammability is defined as the ability of a material to burn which results in combustion or fire. Also they are defined as the capability to burn. Flammables are used where we need to ignite some materials easily and also these materials are more dangerous. The flash point of a flammable material is 100 C. There are many tests which help in determining the degree of flammability. The very two important characteristics of flammables are vapour pressure and flash point. Flash point tells how easy it is to ignite the material’s vapour when it evaporates into the atmosphere. Flash point and flammability are inversely proportional to each other. Lower flash point indicates higher flammability. And if the flash point is higher than lower flammability will be there. Vapour pressure tells about the liquid’s vapour which tends to concentrate in the surrounding atmosphere when liquid evaporates. Flash point and vapour pressure are inversely proportional to each other. As vapour pressure increases flash point decreases which results in higher flammability. Some very good examples for flammable materials are petrol, gasoline, ethanol, acetone, methyl alcohol and so on. Whenever you will purchase flammable container there will be a sign indicating flammable materials.

This is why so important to know what you’re storing and where you’re storing it, you don’t want to have an accident or something that is vaporous can easily ignite and cause a fire in your home.
At Pro-tech, we sell fire extinguishers for the home as well as for commercial. Do you have a fire extinguisher in your house at least on the main floor?
One of our clients has a great story:

“Hi, my name is Allan fine and I’m a client of protechfireandsafety. In 2014 my wife and I were making fondue for the family, and a small container that holds the fuel spilled on our dining room table as my wife was trying to put it out. It caught the entire table on fire as well as splashed on her sweater causing her to go on fire as well.
I heard the screams my office, and quickly ran into my pantry where I had my fire extinguisher that I had purchased from Pro-Tech. I put the fire out and two seconds, my wife froze and my kids were totally freaked out. Thank goodness I had a fire Extinguisher or and might’ve ended up a lot differently”

Combustibles- it is defined as the substances which readily catches fires through fire or combustion. Many safety measures and precaution are taken when using combustible substances. Usually combustibles comes as a by product. When constructing any building or houses fire resistant substances are used. As I said most of combustible substances are produced as a by product. And the popular example for this is wood dust, carbon based dust, magnesium, titanium and many more. There are many tests available which measures the combustibility of a substance. Many combustibles are sometimes suspended in the air which when gets accumulates is a danger for explosions. Usually in construction field, combustibles substances are used. For example wood is used for furniture application and wood is a combustible substance. Therefore materials with low combustibility are used in construction application and that is the reason in construction application fire resistant materials are used. Sometimes to avoid combustion, materials are coated with fire resistant application. The degree of combustibility depends on the chemical composition of substances. Flammability and combustibility are different from each other.
