Safety Guideline when working with Electronics
Safety is the most important thing that a novice or any person should learn in regards to working with electronic circuits and electricity. I am not exaggerating when I say that one mistake can lead to serious injury or death. Specially when you work with high power devices such as televisions, microwaves, and so forth. But, remember that even low power devices such as a VCR can cause serious harm in work on improperly, such as working on it while it is plugged in. This section is not meant to scare you in any way, it is meant to keep you safe.
	Here are some things to remember when working with electronics. Before you work on any electronic circuit or device check once, check twice and make sure that it is unplugged from any power source. This includes but not limited to, wall sockets and batteries. Even if you are lucky or careful enough to work on a device while it is still receiving power, it can still damage your testing equipment. Before you even begin to work on any high power equipment make sure you discharge any capacitors it may contain. Devices such as microwaves contain high power capacitors which may store a lot of electrical current and can give you a shock you are not likely to forget. Second be aware that televisions contain devices that can hold as much as 10,000v, so be very careful. Never work alone, make sure there is someone around that can help you incase of an accident. If by some unfortunate accident you become unconscious by electrical shock or any other reason, this person may just save your life. Another simple but important thing you can do is to wear shoes or sneakers with rubber bottoms. Don't wear jewelry such as rings, necklaces, wrist chains, or any other form of jewelry. These may accidentally come into contact with an electronic component and serve as a conductor for electrical charge. Not to mention that it may become tangle onto something and you pull on it without realizing its tangle and damage a component or device. If you are working on a television or monitor be aware that the picture tube can implode if you hit it with a metal tool. This will cause glass to be sent in every direction at high speeds, this can cause eye damage or other injury. So be very careful when working around them; one thing you can do is wear protective eye wear, but make sure that it doesn't limit your field of vision. Never work when you are tired; don't try to repair or work on any electrical device this can limit you reasoning abilities and can lead to careless mistakes, which can turn dangerous. Never assume that something is safe until you inspect it. Assume towards safety not danger. It is better to assume that it is dangerous, than to assume it is safe. You are more likely to be careful if you think it is dangerous. Last but not least, have fun. Electronics is a fun field to study and to working in, it can also be very lucrative. Specially if you go into repair or designing circuits. Some other things you must be careful with is your equipment. Never leave soldering irons ON without supervision, even if you leave the room for a minute. Soldering irons become very hot, if it comes into contact with a small piece of paper it can catch on fire and spread very quickly. Another things which I can't stress enough is don't work on electric devices while they are plugged in. Do any testing or repair work while the device is unplugged, this will both protect you and your equipment from any damage.
