What is one method to prevent overfilling liquid agents in fire extinguishers?

Using exact measurement by weight or volume is a critical method for preventing overfilling liquid agents in fire extinguishers. This approach ensures that the correct amount of extinguishing agent is loaded into each unit, which is essential for maintaining optimal performance during fire suppression. Overfilling can lead to malfunction, as the pressure and capacity of the extinguisher are not designed to accommodate excess liquid.

By adhering to precise measurement protocols, technicians can ensure that each extinguisher contains the appropriate volume of agent, thereby enhancing safety and effectiveness in emergency situations. Calibration against pre-established standards for both weight and volume is often integral to the servicing process, as it promotes reliability and compliance with safety regulations.

Other methods may contribute to the overall safety and efficacy of fire extinguishers, but the use of exact measurement is foundational for proper maintenance and operation.
