Final answer:
If a smoke detector fails a sensitivity test, the technician should check for any possible reasons for the failure and take appropriate action.
Step-by-step explanation:
If a smoke detector fails a sensitivity test, the technician should check for any possible reasons for the failure. This can include checking for any obstructions that may prevent smoke particles from reaching the ionization chamber, ensuring the batteries are functioning properly, and making sure the sensor is clean and free of dust or debris. If necessary, the technician may need to recalibrate or replace the smoke detector.
For example, if the detector is located near a kitchen or bathroom where steam or cooking fumes are common, the sensitivity test may fail due to false alarms triggered by these non-hazardous particles. In this case, moving the detector to a more suitable location may solve the problem.
It's important to address a failed sensitivity test promptly to ensure the smoke detector can effectively detect and alert to the presence of smoke or fire, reducing the risk of potential harm or damage.
