What must be done before testing smoke detectors with smoke?

Before testing smoke detectors with smoke, it is crucial to refer to the manufacturer’s instructions and exercise caution. Each type of smoke detector may have specific guidelines for testing, including the types of smoke that can be used and the procedures to follow. Following these instructions ensures that the testing is performed safely and effectively, minimizing the risk of damaging the detector or creating a hazardous situation.

Exercising caution is paramount because improper testing can lead to false alarms or may not provide accurate results regarding the detector’s functionality. Additionally, it helps to ensure that the area is safe during testing, preventing any potential safety risks associated with the use of smoke for testing purposes.

The other options may involve safety precautions or procedures but do not directly align with the primary requirement of adhering to manufacturer guidelines and maintaining safety during the testing process.
