What is the relationship between air quality monitoring and worker safety?

• A. It increases product quality.
• B. It helps ensure a safe working environment.
• C. It reduces machine wear.
• D. It improves communication.

Answer: (B)

Air quality monitoring is a safety-focused practice that tracks airborne contaminants and oxygen levels to protect workers. When the monitoring system detects hazardous concentrations, it enables immediate actions—adjusting ventilation, isolating processes, stopping operations, or ensuring the right PPE—so people aren’t exposed to harmful substances. Real-time data and alarms help keep exposures below health-based limits, reducing the risk of acute symptoms and long-term illness. This safety-oriented purpose is why it’s the best answer: the core aim is to keep workers safe, even though monitoring can have indirect effects on other areas, it’s not primarily about product quality, machine wear, or improving communication.
