- Technicians should never wear an anti static wrist strap when working on a monitor, printer or a power supply as these devices contain high voltages.
When a fire breaks out, it is important to know which fire extinguisher to use.
- Class A is used for common fires involving paper, wood, plastic or cardboard fires.
- Class B is used for flammable liquids like gasoline, kerosene and organic solvent fires.
- Class C is used for electrical fires.

- P- pull the pin.
- A- aim at the base of the fire.
- S- squeeze the lever.
- S- sweep the nozzle from left to right or side to side.
There are different types of power outages. This section explains some of the common types.
- A blackout is when there is a complete loss of AC power.
- A brownout is when there is reduced AC power.
- A spike is a sudden increase in power.
- A surge is a dramatic increase in power.
Devices like a surge suppresor helps by diverting an extra electrical voltage that is on the line into the ground. An Uninterruptable Power Supply (UPS) supplies power to a computer when there is an outage.
Disposal of Equipment
Because items like batteries or monitors contain harmful elements, the correct method of disposing them is to comply with the local environmental regulations. If you are unsure about this, contact your local city council to assist you.
Never empty liquids other than water into a sink as it is harmful to the environment and should be disposed of responsibly.
