6.1 Outline the purpose of appropriate safety and environmental procedures and given a scenario apply them
ESD
ESD (Electrostatic Discharge) is the rapid discharge of static electricity from one conductor to another of a different potential. An electrostatic discharge can damage integrated circuits found in computer and communications equipment.
Common causes of ESD are:
Improper grounding
Walking across a rug or carpeted floor
Low humidity (hot and dry conditions)
Ways to protect against ESD include:
The use of a grounding strap or mat
Grounding yourself against the bare metal case before reaching inside the system
Use antistatic sprays or solutions on floors, carpets, and equipment
Static-free carpet used in work areas
Raising humidity levels
EMI
Network interference
Magnets
RFI
Cordless phone interference
Microwaves
