Answer: A
Since fire cannot burn in carbon dioxide, it is an effective
suppressant. However, in a manned operation, the release of
this gas is likely to result in fatalities so automatic
release is inadvisable, if not illegal, and manual release
delays the suppression of the fire. Where an installation is
unmanned, carbon dioxide can be released automatically
should a fire be detected. Halon gas may be released
automatically, as it is breathable by humans and will
suppress a fire. However, since it has an adverse affect on
the earth's ozone layer, its use is discouraged and, in many
countries, banned. Dry-pipe sprinklers, which fill with
water only when the fire is detected, are considered an
appropriate option in manned installations but are not
necessary when people are not present. Wet-pipe sprinklers,
which are filled with water at all times, are not a viable
option for a computer installation due to the risk of leaks.
