Question 45/55
In accordance with ASHRAE Standard 170, general hospital Operating Rooms must have a minimum of two return grilles, one of which must be located:
Correct Answer: D
Comprehensive and Detailed Explanation:
OR Ventilation: ASHRAE Standard 170, Section 7.4.1, mandates at least two return/exhaust grilles in ORs, with one high and one low. The low grille (near the floor) removes heavier contaminants, while the high grille aids in overall air circulation, supporting laminar flow from ceiling diffusers.
Option Analysis:
A/B: Breathing height or anesthetizing location are not specified in ASHRAE 170.
C: Distance is practical but not the primary requirement.
D: Correct-high and low placement is explicitly required.
