Make sure all power sources are disconnected and capacitors are drained before working with a device.
Make sure you are properly grounded, because static electricity contains thousands of volts and can easily fry an intergrated chip.
If possible, work out the circuit on paper before attempting to build it.
Make sure you meet the wattage constraints of each component in the circuit or you may cause severe damage to them. If you see or smell smoke, cut power and then check each piece of the circuit to determine which one you have burned. Blown capacitors make a loud pop and are very easy to spot because it has strewn itself all over the work bench.
Your main concern should be that you and the work area is sitting at earth ground. Some of these IC parts are very sensitive to voltage liKe ESD.

Why do electrical tools and equipment need regular maintenance?
Most electrical tools and equipment are used on live or energized system. If the tools and equipment are not well maintained, user may get electric shock and may even lead to fatal accident.
Electrical safety test should be carried out whenever electrical equipment is commissioned?
Test and inspection of electrical equipment should always be carried out when commissioning . This will done before voltage is applied , usually known as dead testing to verify the suitability . Live testing will then be carried out to confirm compliance with regulations .
What earth size is required for 16mm live and neutral?
Answer for USA, Canada and countries running a 60 Hz supply service.Equipment grounding conductors are not based on the size of the live and neutral conductors. Equipment grounding conductors are based on the amp rating of the circuit, which may or may not be the same ampacity of the conductors of the circuit.However, working backwards, a 16mm conductor is the same as a 3/0 conductor, which is rated for 200amps, which requires an equipment grounding conductor (earth) of at least 6 AWG copper / 4 AWG aluminum. If your circuit is rated higher (usually the breaker size) than 200 amps a larger conductor may be required.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
What is fire classification?
There are 5 classes of fires (3 common and 2 specialty). These are common combustibles, flammable liquids and gases, live electrical equipment, combustible metals, and cooking media. These fires are then each classified into 5 groups.

Why should you avoid bodily contact with ground while working on live electrical equipment?
No-one should work on live electrical equipment without training, and the training would answer that question. Always turn equipment off and unplug before doing any work.
The main reason why you should avoid bodily contact with ground while working on live electrical equipment is that such contact will?
The main reason why you should avoid bodily contact with ground while working on live electrical equipment is that such contact will complete a circuit. If you are in contact with any electricity, this means that your body becomes part of the path for the electricity and it will pass through you as it heads into the ground.

Why live and neutral wire essential for proper working of electrical circuit?
Two wires are always needed to supply electrical equipment so that the current has a complete circuit to flow in. One of the wires is earthed at the supply transformer, that one is called the neutral, and the other one is the live.
