An IS auditor inspected a windowless room containing phone switching and networking equipment and
documentation binders. The room was equipped with two handheld fire extinguishers-one filled with CO2, the
other filled with halon. Which ofthe following should be given the HIGHEST priority in the auditor’s report?

A.
The halon extinguisher should be removed because halon has a negative impact on the atmospheric ozone
layer.

B.
Both fire suppression systems present a risk of suffocation when used in a closed room.

C.
The CO2 extinguisher should be removed, because CO2 is ineffective for suppressing fires involving solid
combustibles (paper).

D.
The documentation binders should be removed from the equipment room to reduce potential risks.

Explanation:
Protecting people’s lives should always be of highest priority in fire suppression activities. COz and halon both
reduce the oxygen ratio in the atmosphere, which can induce serious personal hazards, in many countries
installing or refilling halon fire suppression systems is not allowed. Although COz and halon are effective and
appropriate for fires involving synthetic combustibles and electrical equipment, they are nearly totally ineffective
on solid combustibles (wood andpaper). Although not of highest priority, removal of the documentation would
probably reduce some of the risks.
