Implementing Safety Measures and Procedures
ESD Precautions and Procedures

Situations that could Present a Danger or Hazard

If you do not use ESD protection devices as per the guidelines, you can harm yourself by getting a shock. Consider the following situations:

	An ESD strap is specially designed to drain electric charges away and provide safety to you. For this purpose, it uses 1-megaohm resistor to drain the charge away. If, instead of using this safety device, you wrap a simple wire around your wrist, you can get electrocuted.
	An ESD strap can provide safety against low voltage. If you wear an antistatic wrist strap when there is a possibility to encounter a high-voltage capacitor, the strap could channel that voltage through your body. Such situation could be working on the inside of a monitor or power supply.
	Antistatic bags are not designed to drain the charges away. Do not use them in place of antistatic mats to transfer static charge from the computer to the ground
