Which statement about monitoring instruments is accurate during re-entry?

In re-entry monitoring you need both real-time readings of the main hazards and a way to detect other contaminants as needed. A multi-gas meter gives immediate, real-time measurements of oxygen, flammable gases, and common toxic gases, which is essential for safe entry. If volatile organic compounds are a concern, a PID can be used to provide quick VOC readings, and sorbent tubes can be employed to collect air samples for later laboratory analysis to quantify a broader range of compounds. Using a PID or sorbent tubes in addition to a multi-gas meter lets you tailor the monitoring to the specific conditions, rather than relying on a single instrument. This approach is necessary because an instrument that only detects VOCs or only one gas won’t fully characterize the hazardous atmosphere, oxygen sensors are a critical part of monitoring, and multi-gas meters are standard practice rather than something never used.
