Water Issues (e.g., Leakage, Flooding)

Water issues, such as leakage and flooding, should be addressed in

your environmental safety policy and procedures. Plumbing leaks are
not an everyday occurrence, but when they do happen, they can cause
significant damage.

Water and electricity don’t mix. If your computer systems come in
contact with water, especially while they are operating, damage is sure
to occur. Plus, water and electricity create a serious risk of

electrocution for nearby personnel. Whenever possible, locate server
rooms, datacenters, and critical computer equipment away from any
water source or transport pipes. You may also want to install water
detection circuits on the floor around mission-critical systems. Water-
detection circuits will sound an alarm and alert you if water is
encroaching upon the equipment.

To minimize emergencies, be familiar with shutoff valves and drainage

locations. In addition to monitoring for plumbing leaks, you should
evaluate your facility’s ability to handle severe rain or flooding in its
vicinity. Is the facility located on a hill or in a valley? Is there sufficient
drainage? Is there a history of flooding or accumulation of standing
water? Is a server room in the basement or on the first floor?
