A smoke system is a type of fire suppression system that uses smoke to contain a fire. It is a form of passive fire protection, meaning that it does not require any active intervention from people or other fire suppression systems. Smoke systems work by releasing a dense smoke that blocks the oxygen supply to the fire, thus extinguishing it. The smoke also serves to alert people to the presence of a fire, allowing them to evacuate quickly and safely. Smoke systems are typically used in large buildings such as warehouses, factories, and shopping malls, where a fire can spread quickly and cause significant damage. Smoke systems are also used in aircraft and ships, where the presence of smoke can help to contain a fire and alert people to its presence. Smoke systems are an effective way to protect people and property from the dangers of fire.
