Question

• A. Carbon dioxide
• B. Halon gas system
• C. Dry Pipe
• D. None of these can be used

Answer 1

The correct option is C Dry Pipe

Dry Pipe cannot be used for extinguishing the fire in a computer room.

A dry fire suppression system work:-

A dry pipe sprinkler system is one in which pipes are filled with pressurized air or nitrogen, rather than water. Located in a heated space, the dry-pipe valve prevents water from entering the pipe until a fire causes one or more sprinklers to operate.

Dry pipe systems require additional control equipment and air pressure supply components which increases system complexity. Without proper maintenance, this equipment may be less reliable than a comparable wet pipe system.
