36 Researching the requirements
conditioning systems should be designed to inhibitthe spread of fire, heat,
and smoke from one part of a building to another. Smoke detectors should
also be installed.
Services such as steam, water, and power should be checked regu.Iarly, and
pipes should be inspected for excess condensation,.leaks, and corrosion. If
power connections are made beneath a raised floor, waterproof electrical
receptacles and connectors should be used.
Recommended fire extinguishing systems
In
most cases,
carbon dioxide or water sprinkler systems are to be used.
Water sprinklers are generally less expensive than the carbon dioxide kind.
Specifically, dry-pipe water sprinklers are strongly recommended since this
type will interrupt power to the room and open a master valve to fill the
overhead sprinklers.
Carbon dioxide systems are also effective in containing a fire, but they
quickly exhaust the available oxygen supply. If a carbon dioxide system is
used, an alarm should sound warning onsite personnel of the release of
carbon dioxide. For health and safety reasons, employees must be
evacuated within 30 seconds of the release.
