8. Object 1 Object 2 Static Electricity Object 1 Object 2

9. ESD

10. ESD Prevention Techniques • Remove activities and tasks. • Use anti-static materials. • Maintain air quality. • Use grounding techniques.

11. EMI 3G Cell Site

12. EMI Prevention Techniques • Twisted-pair implementations • Cautious wiring techniques • SMD technology implementation • Electromagnetic shielding

13. An ESD Toolkit • Wrist or ankle strap • Grounded floor mat or grounded work-surface mat • Anti-static bags • ESD smock

14. Electrical Hazards • Electrocution • Electric shock • Burns • Collateral injuries

15. Electrical Safety Precautions • Perform only the work for which you have sufficient training. • Do not attempt repair work when you are tired. • Do not assume anything without checking it out for yourself. • Do not wear jewelry or other articles that could accidentally contact circuitry and conduct current. • Wear rubber-soled shoes to insulate yourself from ground. • Suspend work during an electrical storm. • Do not handle electrical equipment when your hands or feet are wet or when you are standing on a wet surface • Prevent static electricity from damaging components by standing on a totally insulated rubber mat to increase the resistance of the path to ground. • When removing circuit boards, place them on a dissipative ground mat or put them in an anti-static bag.

16. Electrical Safety Precautions (Cont.) • Use an anti-static wrist strap when handling static-sensitive components. • After cleaning the keyboard, be completely sure it is dry before powering it up. • Label wires and connectors as you detach them, and make sure you plug them back into the proper sockets in the proper order. • When you replace the computer’s case, make sure all the wires are inside. • Power supplies have a high voltage in them any time the computer is plugged in. • Never stick anything into the power supply fan to get it to rotate. • Do not take the case off a monitor. • Do not bang on the monitor screen with your tools; an implosion will propel shards of glass in every direction. • To clean the monitor, turn it off and unplug it; do not wear an anti-static wrist strap.

17. Atmospheric Considerations • Ozone gas • Humidity • Dust

18. Situational Hazards • Falling and tripping • Equipment storage • Food and drink

19. Physical Hazards • Cords and cables • Lasers • RSI • Eye strain • Radiation • Noise • Hot components

20. Safety Precautions for Physical Hazards • Cords and cables: Use cord protectors to prevent tripping. • Lasers: • Never point a laser beam in someone’s eyes. • Never look directly at a laser beam. • Never disable safety mechanisms for embedded lasers. • RSI: • Rest, therapy, surgery, prevention. • Eyestrain: • Special glasses. • Artificial tears. • Noise: • Keep printers separate. • Noise reduction hoods.

21. Equipment Moving Safety Recommendations • Know your own strengths and weaknesses. • Bend at your knees. • Assess the equipment you are moving. • Take special precautions because the equipment may be unstable for lifting. • Do not stack equipment while moving. • Plan ahead.

22. Liquid Hazards • Compounds are used to clean or condition equipment. • Read the labels and follow instructions carefully when disposing of materials.

23. Chemical Hazards • Laser printer toner • Batteries • Capacitors
