What action is required if hazardous vapors are detected during testing?

• A. Suspend testing until hazards are mitigated.
• B. Continue with reduced exposure.
• C. Vent vapors into the test area.
• D. Proceed with caution.

Answer: (A)

When hazardous vapors are detected during testing, the first and required step is to suspend the test until the hazard is mitigated. This stops exposure and reduces the risk of inhalation or ignition in a confined testing environment. After stopping, address the source of the vapors, improve ventilation, and verify that gas detectors read safe levels before resuming. Continuing with reduced exposure, venting vapors into the test area, or proceeding with caution would not remove the hazard and could put people at serious risk.
