What precautions should you take when working with electronics?
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.
A hurricane watch means conditions are favorable for a hurricane to develop, or if it has developed, it may approach your area. This is when you should start planning on precautions to take should it turn into a hurricane warning. A hurricane warning means one has developed and is predicted to hit your area. This is when you should start taking immediate precautions. For information on what precautions to take during a hurricane, see the…
In the wild, tigers roam a huge territory, so protecting a tiger's habitat, and guarding it from poachers, are two precautions to take. Also, it is important to ensure there are enough prey animals for the tiger to stalk and kill within the protected tiger reserve. If natural prey is scarce the tiger may roam onto surrounding farms and kill livestock, or people working or venturing into the forest.
