A smoke hood is a safety device designed to protect individuals from smoke and toxic gases during a fire. It typically consists of a hood that covers the head and neck, along with a filter system that cleans the air before it is inhaled. Smoke hoods are often used in emergency situations, such as building evacuations, to help people escape hazardous environments. These devices are commonly found in public buildings, such as schools and offices, and are part of fire safety equipment. They are designed to be lightweight and portable, making them easy to use in emergencies. Proper training on how to use a smoke hood can enhance its effectiveness in protecting lives during a fire.
