Topic A: Use Appropriate Safety Procedures

Standby Power Supply (SPS)
Temperature and Humidity Control

Standby Power Supply (SPS)

A device similar to a UPS is a Standby Power supply (SPS). Much like a Uninterruptible Power supply (UPS), an SPS contains a battery, but an SPS battery provides power to the computer only when it loses AC power.

It might not provide constant power, as a UPS does. It might use a simulated sine wave. An SPS is not as effective as a UPS because the SPS must detect a power-out condition first and then switch over to the battery to supply power to the computer. As a result, SPS switching time is important. Any time under 5 milliseconds is fine for most systems.

Fire Safety

It is rare for electrical fires to occur in computers, but it is important to have electrical fire safety knowledge in case a fire does happen. If a fire occurs inside a computer or peripheral, unplug the equipment, if possible, but do not put yourself in harm’s way in attempting to do this.

Extinguishers

A Type C or Type A-B-C fire extinguisher can be used to put out the fire. Type C fire extinguishers are made specifically for electrical (Type C) fires. Type A-B-C fire extinguishers can be used for Class A, Class B, and Class C fires. Here’s some quick information about classes of fires:
  • Class A fires involve paper, wood, cloth, or other normal combustibles.
  • Class B fires involve flammable liquids and gases.
  • Class C fires involve electrical or electronic equipment.
