Which of the following is TRUE for tele communications spaces?

Question

Options

• AMaintain aim (3.28 ft) clearance between equipment and plumbing fixtures such as mop sinks
• BPlumbing piping not related to the support of the space should not pass through the space.
• CRelative humidity snail be maintained at 40% ?5%.
• DClose proximity to water service is desired so consider locating the ER in the pipe chase.

• A
  19% (5)
• B
  70% (19)
• C
  4% (1)
• D
  7% (2)

Explanation

Option B is correct because telecommunications spaces (equipment rooms and telecommunications rooms) must be protected from water damage - any plumbing unrelated to the space's own support functions (e.g., HVAC condensate) should be routed around, not through, the space, per ANSI/TIA-569 standards.

Why the distractors are wrong:

• A is incorrect because the standard does not require a 1m (3.28 ft) clearance between equipment and mop sinks - it prohibits unrelated plumbing entirely, making proximity to a mop sink a non-starter.
• C is incorrect on the numbers; applicable standards (ASHRAE/TIA) typically specify a relative humidity range of approximately 30–55%, not the narrow 40% ±5% band stated.
• D is the opposite of correct practice - locating an equipment room in a pipe chase deliberately places sensitive electronics adjacent to water supply lines, maximizing leak risk.

Memory tip: Think of a telecom room as hydrophobic - it fears water. The rule is simple: if a pipe has no business being there, it shouldn't be there. Any answer suggesting water proximity is "desired" is an automatic red flag.
