Which of the following is a required feature of compressors in terms of safety?

An automatic shut-off valve is a required safety feature in compressors because it helps prevent over-pressurization, which can lead to catastrophic failures or accidents. This feature automatically engages to stop the operation of the compressor if it detects that the pressure has exceeded predetermined safe limits. This is crucial in maintaining operational safety by protecting the equipment, operators, and surrounding environment from potentially hazardous situations. The automatic shut-off valve serves as a critical safeguard, ensuring that the compressor functions within its designed pressure range and reducing the risk of incidents that could occur due to excessive pressure buildup.
