Correct Answer: B
Explanation/Reference:
Explanation:
Ventilation has several requirements that must be met to ensure a safe and comfortable environment. A closed-loop recirculating air-conditioning system should be installed to maintain air quality. "Closed-loop" means the air within the building is reused after it has been properly filtered, instead of bringing outside air in. Positive pressurization and ventilation should also be implemented to control contamination. Positive pressurization means that when an employee opens a door, the air goes out, and outside air does not come in. If a facility were on fire, you would want the smoke to go out the doors instead of being pushed back in when people are fleeing.
Incorrect Answers:
A: Positive pressurization does not mean the pressure inside your sprinkler system is greater than zero.
Therefore, this answer is incorrect.
C: Positive pressurization does not cause the sprinkler system to go off. Therefore, this answer is incorrect.
D: Positive pressurization is not a series of measures that increase pressure on employees in order to make them more productive. Therefore, this answer is incorrect.
