 Here are some rules to follow in handling electrical equipment. So we're actually going to work with hot substances. So again, protect yourself with gloves and wear your eye gear. So in this case, I'm using a hot plate as an example. So before you use this equipment, what you want to do is to check the cords and make sure that you have no frays or exposed wires. Make sure that the plug is secure before you do any plug-in. If you find that anything is wrong with the cord, make sure you inform your instructor immediately. So when handling the equipment, make sure you follow your instructor's guidelines as to how to do so. Only turn on the equipment when the instructor tells you to do that. So for example, I'm going to use this hot plate to boil water. So I make sure I plug in the plate and then I turn the dial to whatever temperature I want to keep the hot plate at to boil my water. So if you notice this hot plate, once it's on, it's going to show that it's hot. So this gives an idea that you have to be careful. So when the water is already placed on the hot plate for a while, it will get hot. So never hold the hot beaker with your bare hands because this will cause severe burns. In the lab, you'll be provided with a heat-resistant glove or a rubber device that is kind of neat because it has these rubber grooves. So it will grab onto the hot beaker without it slipping from your hands. So personally, I like this one, so I'm going to use it to remove the beaker from off the hot plate. So I'm finished with the hot plate now. So what I want to do is to turn it off. So I turn it off and then I make sure I plug the equipment out. So it's still hot. And if your classmates look at this, they may not know it's hot because you cannot tell by looking. But of course, if you put your hand there, you know definitely it's hot. You don't want to do that. So you make sure you put this away securely out of the way of anyone so that they won't touch it and hence they won't harm themselves.
