Answer :
Final answer:
A Gas detector is specifically designed to detect flammable or explosive atmospheres, unlike smoke, heat, or carbon monoxide detectors, which are aimed at detecting smoke, changes in temperature, and carbon monoxide gas respectively.
Explanation:
The device designed solely to detect flammable or explosive atmospheres is a Gas detector. Other detectors like smoke detectors, heat detectors, and carbon monoxide detectors serve different purposes. Smoke detectors are crucial for detecting the presence of smoke, often indicating a fire. Heat detectors respond to changes in temperature, providing alerts in situations where smoke detectors may not, such as in environments with heavy dust or fumes that could obscure smoke. Carbon monoxide detectors are essential for detecting the presence of carbon monoxide gas, which is tasteless and odorless, thus preventing carbon monoxide poisoning. However, for detecting flammable or explosive atmospheres, especially in industrial settings where these conditions could lead to significant hazards, gas detectors are specifically designed. They monitor the concentration of flammable gas in the air and trigger an alert before these levels reach a lower explosive limit (LEL), ensuring safety and preventing potential explosions or fires.
