What is a fugitive emission and why is it important to monitor?

• A. Emission from exhaust stack with monitors in place.
• B. Emission captured by standard monitoring.
• C. Uncontrolled leakage or emission of contaminants from equipment or processes; can cause exposures not captured by routine monitoring.
• D. Emission only during start-up.

Answer: (C)

Fugitive emissions are uncontrolled leaks or releases of contaminants from equipment or processes that escape containment and are not captured by routine monitoring. They matter because these leaks often occur at seals, gaskets, valves, flanges, sampling lines, or other fittings and may be intermittent or small, yet they can expose workers and contribute to environmental releases in ways that standard stack or vent measurements miss. That’s why monitoring is important: it identifies leaks that routine monitoring misses, enabling prompt repair and control through leak detection and repair programs, infrared or handheld detectors, and regular maintenance. These emissions can happen at any time, not just during startup, so ongoing vigilance protects health, reduces environmental impact, and supports regulatory compliance.
