Science labs are full of amazing things, but some of them can be dangerous if not used carefully. To understand fire safety in the lab, we first need to know what a fire needs to start. It's simple: fire needs three things to exist. This is called the Fire Triangle

If you take away any one of these three things, a fire cannot start. If a fire is already burning, it will go out. All lab fire safety is about keeping these three things separate.

The most obvious source of heat in a school lab is the Bunsen burner It produces a hot, open flame that can easily set things on fire. You must always be aware of where the flame is and keep flammable things away from it.

Another source of heat is electricity. Faulty wires or sparks from electrical equipment, like power packs, can get very hot. These sparks can act as the 'heat' part of the Fire Triangle, igniting any nearby fuel.

What can burn in a lab? Lots of things. We call these things 'fuel'. Some fuels are obvious, like paper from your notebook or loose clothing. Long hair can also be a fuel if it gets too close to a flame.

Other fuels are less obvious. Many chemicals are flammable, meaning they can catch fire easily. A common one in school labs is ethanol It's a clear liquid that looks like water, but it is very flammable.

The final part of the triangle is oxygen. We don't need to worry about bringing oxygen into the lab, because it's already all around us in the air. This is why it's so important to control the heat and the fuel.

Now, let's check what you've learned about keeping the lab safe.

By understanding the Fire Triangle, you can easily spot and avoid fire hazards in the lab. Always think about keeping heat sources and fuel sources far apart.
