What is the service pressure limitation when servicing stored-pressure extinguishers?

• A. Must not exceed 3x the factory test pressure
• B. Must be greater than factory test pressure
• C. Must exceed 2x the service pressure
• D. Must be equal to factory test pressure

Answer: (A)

The service pressure limitation for stored-pressure extinguishers is determined by safety standards and manufacturing guidelines. When servicing these extinguishers, the service pressure must not exceed three times the factory test pressure. This guideline ensures that the extinguisher can withstand the pressures during operation and testing without risking failure or rupture. By maintaining this limitation, the integrity of the extinguisher is preserved, ensuring that it can safely hold and discharge the pressurized agent when needed. The factory test pressure represents the maximum safe pressure that the extinguisher is designed to handle, so any service pressure exceeding this range could potentially compromise the safety and reliability of the extinguisher in an emergency situation.
