Damage

Addressing fire detection and suppression includes dealing with
possible contamination and damage caused by a fire. The destructive

elements of a fire include smoke and heat, but they also include the
suppression media, such as water or soda acid. Smoke is damaging to
most storage devices. Heat can damage any electronic or computer
component. For example, temperatures of 100 degrees Fahrenheit can
damage storage tapes, 175 degrees can damage computer hardware

(that is, central processing unit [CPU] and random-access member
[RAM]), and 350 degrees can damage paper products (through
warping and discoloration).

Suppression media can cause short circuits, initiate corrosion, or
otherwise render equipment useless. All these issues must be
addressed when designing a fire response system.

Don’t forget that in the event of a fire, in addition to

damage caused by the flames and your chosen suppression
medium, members of the fire department may inflict damage using
their hoses to spray water and their axes while searching for hot
spots.
