✔✔Electromagnetic Interference - ✔✔Caused by electronic Motors, lightning, etc
✔✔Radio Frequency Interference - ✔✔Caused by Components of Electrical System,
Cables, Fluorescent Lighting, Truck Ignitions. Can cause permanent damage to
sensitive system components
✔✔Magnetic Media - ✔✔Affected from 100 degrees Fahrenheit
✔✔Disks - ✔✔Damaged at 150 degrees Fahrenheit
✔✔Computer equipment - ✔✔Damaged at 175 degrees Fahrenheit
✔✔Paper products - ✔✔Damaged at 350 degrees Fahrenheit
✔✔EMI- Common Mode Noise - ✔✔Noise from Radiation Generated by the difference
between Hot and Ground wires
✔✔EMI- Traverse Mode Noise - ✔✔Noise from Radiation Generated by the difference
between Hot and Neutral wires
✔✔Brownout - ✔✔Prolong loss of power
✔✔Project Initiation - ✔✔Involves getting management support, developing the scope
of the plan, and securing funding and resources
✔✔Transients - ✔✔Line noise that is superimposed on the supply Circuit can cause
fluctuation in power
✔✔Inrush Current - ✔✔The initial surge of current required when there is an increase in
power demand i.e starting a large motor
, ✔✔Electrostatic Discharge - ✔✔Power surge generated by a person or device
contacting another device and transferring high voltage shock. Affected by low humidity
✔✔Greater than 60 - ✔✔Causes problems with condensation on computer equipment,
corrosion of electrical connections
✔✔Less than 40 - ✔✔Causes Increase in Electrostatic Discharge, up 4000 Volts under
normal humidity and up to 25000 volts under very low humidity
✔✔Hygrometer - ✔✔Measure humidity levels
✔✔40 Volts - ✔✔Static charge damage Sensitive Circuits and Transistors
✔✔1000 Volts - ✔✔Static charge damage Scramble Monitor Display
✔✔1500 Volts - ✔✔Static charge damage Disk Drive, causing data loss
✔✔2000 Volts - ✔✔Static charge damage System Shutdown
✔✔4000 Volts - ✔✔Static charge damage Printer Jam
✔✔17000 Volts - ✔✔Static charge damage Permanent Chip
✔✔Class A Fire - ✔✔Common Combustibles such as paper, wood, furniture, clothing -
Water, Foam
✔✔Class B Fire - ✔✔Burnable fuels such as gasoline, oil, or alcohol - Inert Gas, CO2
✔✔Class C Fire - ✔✔Electrical fires such as computers and electronics - Inert Gas,
CO2 - Turn off electricity first
✔✔Class D Fire - ✔✔Special Fires, such as chemical, metal - Dry powder
✔✔Class K Fire - ✔✔Commercial Kitchens - Wet Chemicals
✔✔Wet Pipe - ✔✔Always contains water - most popular and reliable, 165 Fuse Melts -
can freeze in winter - pipe breaks can cause floods
✔✔Dry Pipe - ✔✔No water in Pipe - preferred for computer installations, use a clapper
to hold the water, air blows out of pipe
✔✔Deluge - ✔✔Water Discharge is large, not recommended for computer installations
