Which of the following is NOT a benefit of using smoke detectors?

The choice that indicates "elimination of all fire risks" is not a benefit of using smoke detectors. While smoke detectors are highly effective tools for early fire detection, they do not prevent fires from occurring or eliminate the inherent risks associated with fire. They provide crucial alerts that can allow occupants to evacuate safely and respond quickly, which directly contributes to minimizing injury and damages.

Early detection can lead to a timely response by firefighters, reducing potential financial losses and lessening the likelihood of severe smoke inhalation incidents. However, the act of simply installing smoke detectors does not completely remove the possibility of fires, which can still arise from various sources such as electrical failures, cooking accidents, or external factors. Thus, while smoke detectors are vital in enhancing safety and mitigating risks, they cannot guarantee the complete eradication of fire risks.
