Module 4 - Safety Labs Procedures and Proper Use of Tools Flashcards
A safe workspace is…
Clean, Organized, Properly Lit
(True or False) Some printer components retain a high voltage even after the printer is turned off.
True
(True or False) Electrical devices have certain power requirements.
True
(True or False) Exchanging AC adapters with a different type of laptop or device will not cause damage to either AC adapter or the laptop.
False, it will damage both.
P-A-S-S, the basic rules of fire extinguisher operation means…
P - Pull the pin
A - Aim at the base of the fire, not at the flames
S - Squeeze the lever
S - Sweep the nozzle from side to side
This can occur when there is a build up of a static electricity charge that exists on a surface which comes into contact with another, differently charged surface. This can cause damage to computer equipment if not discharged properly.
Electrostatic Discharge (ESD)
(True or False) Less than 30 volts of static electricity can damage a computer component.
True
It is the intrusion of outside electromagnetic signals in a transmission media, such as copper cabling. In a network environment, this distorts the signals so that the receiving devices have difficulty interpreting them.
Electromagnetic Interference (EMI)
Possible sources of Electromagnetic Interference (EMI):
Any source designed to generate electromagnetic energy
Man-made sources like power lines or motors
Natural events such as electrical storms, solar and interstellar radiations
It is caused by radio transmitters and other devices transmitting in the same frequency. Wireless networks are affected by this.
Radio Frequency Interference (RFI)
(True or False) If the humidity level is very low, the chance of ESD decreases.
False, it increases.
(True or False) If the humidity level is very high, equipment won’t suffer from moisture damage.
False, they will be damaged.
It is the measure of energy required to move a charge from one location to another.
Voltage
The movement of electrons.
Current
(True or False) Unsteady voltages are called power flunctuations.
True
