Flammability limits

Flammability limits are like a game of Goldilocks and the Three Bears, but instead of porridge, it's all about fire.

You see, just like how Goldilocks wanted her porridge to be just right, fire also needs the right amount of air and fuel to burn properly. Too much air or fuel, and the fire won't burn at all. Too little air or fuel, and the fire will also go out.

Flammability limits are like the sweet spot where the fire has just the right amount of air and fuel to keep burning. There are two types of flammability limits: the upper limit and the lower limit.

The upper limit is when there is too much fuel and not enough air, so the fire can't burn anymore. It's like trying to blow up a balloon too much - eventually it will pop and won't get any bigger.

The lower limit is when there is too much air and not enough fuel, so the fire can't burn either. It's like trying to light a candle with a tiny flame - there's not enough heat to start a bigger flame.

Knowing the flammability limits of different substances, like gasoline or propane, can help keep us safe. We can make sure to store them properly and avoid using them near anything that could cause a spark or flame. It's like making sure to keep scissors away from your fingers - it's just safer that way!
