1. Alarm switch. The "alarm switch" symbol with red background and yellow characters, the arrow pointing to the position is the button, and pushing down indicates the alarm phone.
2. Fire extinguisher. Among the fire-fighting equipment, the most common one is the fire extinguisher. In public places, the location of the dry powder fire extinguisher box is of course particularly prominent, with a "fire extinguisher" sign posted on it.
3. Safe exit. The Fujie fire equipment reminds us that in public gathering places, we need to first understand where several safety exits are located. If a fire occurs, we can quickly and orderly evacuate to a safe area along the safety evacuation route. Generally, there are emergency lighting fixtures on the floor, and a "safety exit" sign can be seen.
4. Fire hydrant. It is generally placed in public shared spaces such as corridors or halls, with prominent markings (indicating "fire hydrant") and nearby fire hoses. At the same time, there should be no obstacles in front of it to avoid affecting the opening of the fire hydrant door. 
We don't want a fire to happen, but being prepared is always good.
