What happens if a sample contains one of the targeted gases?

• A. The infrared signature is detected by the pyroelectric detector and sent to the network module for analysis and subsequent action
• B. The sample is discarded
• C. The sensor triggers an audible alarm only
• D. The sample is placed in a buffer and reanalyzed

Answer: (B)

In this protocol, a sample that contains one of the targeted gases is considered unsuitable for ongoing testing and must be discarded to protect safety and prevent cross-contamination of future samples. Even though the detection system can identify the gas and may communicate findings or trigger alarms, the defined action for this situation is to discard the sample to keep the testing process clean and safe. Other responses describe different responses to detection (like alarming or reanalyzing) but do not align with the stated procedure for handling a compromised sample.
