In which zone should the fire extinguisher pressure gauge needle be for normal operation?
2 Answers
The fire extinguisher pressure gauge needle is normal when it is in the green zone. Additional information about the fire extinguisher pressure gauge is as follows: 1. When the fire extinguisher pressure gauge needle points to the green zone, it indicates that it can be used safely. 2. When the fire extinguisher pressure gauge needle points to the red zone, it indicates insufficient pressure inside the cylinder, making it unusable and requiring replacement. 3. When the fire extinguisher pressure gauge needle points to the yellow zone, it indicates excessive pressure, which can be dangerous, and the extinguisher should be sent to a specialized agency for inspection and repair. 4. The fire extinguisher pressure gauge is an important indicator to determine whether the extinguisher can be used normally, so it should be observed frequently and inspected and maintained regularly.
I remember one summer when I was driving on a trip, and suddenly my car started smoking. I quickly grabbed the fire extinguisher and saw the needle pointing to the green zone, which immediately put me at ease. The pressure gauge on a fire extinguisher should normally be in the green zone, indicating that the internal pressure is just right for discharging the extinguishing agent. If the needle drops into the red zone, the pressure is too low, and it might fail to discharge during an emergency. If it rises too high into the yellow or beyond, there could be a risk of explosion. This device is highly affected by temperature—pressure tends to be lower in cold weather—but regular checks should always ensure it stays in the green zone. I check it monthly by gently rotating the canister to inspect the needle, ensuring it’s ready to save lives in critical moments. Though small, a car fire extinguisher is a safety essential that shouldn’t be overlooked.
