Answer :
Final answer:
A pressure relief valve would protect the reservoirs from becoming over pressurized and bursting if the governor valve fails to "unload" the compressor.
Explanation:
If the governor valve fails to "unload" the compressor, the reservoirs can be protected from becoming over pressurized and bursting by a pressure relief valve. A pressure relief valve is designed to automatically open and release excessive pressure when it exceeds a certain threshold. This helps to prevent damage to the system and ensures the safety of the reservoirs and other components.
