Where is the fire extinguisher pressure gauge pointer normal?
In daily life, fire extinguishers are an important tool for us to deal with fires. The pressure gauge of the fire extinguisher is a key component that reflects the status of the fire extinguisher. So, where is the pressure gauge pointer of the fire extinguisher normal? To understand this problem, we must first have a deep understanding of the principle of fire extinguishers and how to use them.
The working principle of a fire extinguisher mainly depends on the pressure stored inside it. When the pointer points to the green area, it means that the internal pressure of the fire extinguisher is normal and can be used normally. At this point, we can hold the fire extinguisher with confidence, press the operating handle, and spray the extinguishing agent towards the flames. And when the pointer points to the red area, it means that the fire extinguisher is under insufficient pressure or fails, and we should avoid using the fire extinguisher to avoid causing greater danger in the fire.
In terms of details, we can observe that the pointer of the fire extinguisher's pressure gauge is colored, usually in red, green, and yellow colors. The red area represents excessive or abnormal pressure, which is an abnormal state; The green zone is the normal pressure range; A yellow area indicates that the pressure is too low. During normal use, we should always check the position of the pointer of the pressure gauge to ensure that it is in the green area.
So, how do you check the pressure gauge of a fire extinguisher? First, we should easily open the safety latch of the fire extinguisher, and then observe the position of the pointer of the pressure gauge. If the pointer is in the green zone, then the fire extinguisher can be used with confidence; If the hands are in the red or yellow area, then they need to be repaired or replaced. In addition, we can also tell if it is normal by listening to the sound of the fire extinguisher. If the fire extinguisher hiss or buzzes, then its internal pressure is normal; If you can't hear the sound, it may be out of service.
Fire is a common disaster in our daily lives. As an important tool for us to deal with fire, the normal or not fire extinguisher is directly related to our life safety. Therefore, each of us should know how to use the fire extinguisher and how to check it to ensure that the fire extinguisher can be used in a timely and effective manner to extinguish the fire when a fire occurs.
For homes and businesses, the inspection and maintenance of fire extinguishers is very important. We should regularly check the pressure gauge pointer position of the fire extinguisher to make sure it is in the green zone. At the same time, we should also inflate the fire extinguisher regularly or replace the extinguishing agent to ensure that it is always in good working order. In addition, we should also understand that different types of fire extinguishers should be used for different types of fires and how to use them correctly.
In conclusion, it is very important to know the normal state and usage methods of the fire extinguisher. By regularly inspecting and maintaining fire extinguishers, we can ensure that they can perform their best in the event of a fire and protect our lives and property. At the same time, we should also strengthen fire safety awareness and master basic fire fighting and escape skills to deal with possible fire accidents.
