Electronics Engineering (ELEX) Board Practice Exam

Which of the following gases is relevant for monitoring in a building system?

1. Carbon Monoxide

2. Oxygen

3. Natural Gas

4. All of the choices

The correct answer is: All of the choices

Monitoring gases within building systems is crucial for ensuring safety, health, and proper ventilation. Each of the gases mentioned plays a significant role in different contexts. Carbon monoxide is a colorless, odorless gas that can be produced through incomplete combustion in appliances like furnaces, stoves, or fireplaces. Its buildup can be hazardous, making monitoring essential for safety. Oxygen levels are vital for maintaining a healthy environment. Insufficient oxygen can impact occupant well-being, particularly in enclosed spaces or poorly ventilated areas. Therefore, monitoring oxygen levels ensures that air quality remains safe and within ideal parameters. Natural gas, primarily methane, is commonly used for heating and cooking. While it is energy-efficient, leaks can pose serious risks of explosion or asphyxiation, which emphasizes the need for monitoring in any setting utilizing gas appliances. Considering all these factors, monitoring all these gases in a building system represents a comprehensive approach to ensure safety and health. Each gas serves a specific purpose in the context of building management, ensuring that not only is the environment safe, but it is also conducive for occupants.
