Which of the following best describes the benefits of proper ventilation in CNG facilities?

Proper ventilation in CNG facilities plays a crucial role in maintaining safety standards and mitigating risks associated with gas accumulation. The primary benefit of effective ventilation is its ability to reduce the risk of gas build-up, which can lead to dangerous situations such as explosions.

CNG is lighter than air, so in the event of a leak, the gas will rise. However, if the site is not adequately ventilated, there could be areas where combustible gas accumulates, creating a potentially explosive environment. Proper ventilation ensures that any escaping gas is dispersed safely into the atmosphere, thus minimizing the risk of ignition and harmful incidents.

While preventing overheating of equipment, ensuring constant pressure in storage tanks, and improving fuel efficiency are important factors in facility operations, they do not directly address the critical safety concerns related to gas leaks and explosions. The safety aspect of proper ventilation is paramount in CNG operations, making it the most relevant benefit in this context.
