Key Concepts

-
Hydrostatic Testing
This is a method that involves filling a pressure vessel with a liquid and then subjecting it to a pressure higher than its normal operating pressure to check for leaks, cracks, or other forms of structural failure. It is a controlled, safe way to simulate the stresses the container might experience during its service life.
Pressure Vessel Integrity
Ensuring that containers such as fire extinguishers can safely withstand internal pressures is vital to prevent catastrophic failures. The test examines whether the extinguisher’s structure has degraded or weakened over time due to factors like corrosion or material fatigue, which can compromise its ability to safely contain pressurized contents.
Catastrophic Failure Prevention
By detecting potential weaknesses in the container before they lead to failure, hydrostatic tests serve to avert dangerous incidents like explosions or ruptures. This proactive assessment helps mitigate risks associated with overpressure hazards, thereby protecting both users and property.

Initially, 10-ft3 (283 L) L fire extinguisher contains 2.270 kg of CO2 at 25°C. To determine whether the fire extinguisher is full, a pressure test is run. What should the pressure gauge read, in lb/in2, if the fire extinguisher is full?
