In densely populated rooms, CO2 monitors must be located a minimum of how many feet (meters) above the floor?
A . 2 ft. (0.6 m)
B . 3 ft. (0.9 m)
C . 4 ft. (1.2 m)
D . 5 ft. (1.5 m)

Answer: C

Explanation:

In densely populated rooms, CO2 monitors must be located a minimum of 4 feet (1.2 meters) above the floor. This is to ensure that the monitors are able to accurately measure the CO2 levels in the breathing zone of the occupants, which can help in maintaining good indoor air quality.

In rooms that are densely populated, CO2 monitors must be located a minimum of 4 feet (1.2 meters) above the floor. This placement ensures that the monitors can accurately measure the concentration of CO2 in the breathing zone of the occupants, providing reliable data that can be used to assess and control indoor air quality. Proper placement of CO2 monitors is critical for effective ventilation and for maintaining a healthy indoor environment, especially in areas with high occupancy where CO2 levels can rise quickly and impact comfort and well-being.
