The presentation should be engaging for the audience (you can direct it to a specific audience or your general community), and should summarize all of the important research and findings. The presentation should include: detailed explanation of how smoke detectors and carbon monoxide detectors work and suggestions for use (number, mounting locations, etc.) specific explanations of how different fire extinguishers (at least three types) work, advantages and disadvantages of each type, and effectiveness of each extinguisher fire safety facts, equipment, or strategies that you came across in your research or interviews that would make your presentation useful for your audience
Smoke detectors:
Also called a smoke alarm is a device that detects smoke, typically as an indicator of fire. Commercial, industrial, and mass residential devices issue a signal to a fire alarm system, while household detectors, known as smoke alarms, generally issue a local audible or visual alarm from the detector itself. Smoke detectors are typically housed in a disk-shaped plastic enclosure about 150 millimetres (6 in) in diameter and 25 millimetres (1 in) thick, but the shape can vary by manufacturer or product line. Most smoke detectors work either by optical detection (photoelectric) or by physical process (ionization), while others use both detection methods to increase sensitivity to smoke. Sensitive alarms can be used to detect, and thus deter, smoking in areas where it is banned such as toilets and schools. Smoke detectors in large commercial, industrial, and residential buildings are usually powered by a central fire alarm system, which is powered by the building power with a battery backup. However, in many single family detached and smaller multiple family housings, a smoke alarm is often powered only by a single disposable battery.
Carbon Monoxide: a device that detects the presence of the carbon monoxide (CO) gas in order to prevent carbon monoxide poisoning. In the
