What is the most important personal protective equipment (PPE) when troubleshooting pneumatic circuits?

Safety glasses are crucial personal protective equipment (PPE) when troubleshooting pneumatic circuits due to the risk of flying debris, pressurized air, and potential fluid leakage that can cause eye injuries. Pneumatic systems often involve high-pressure components that, if malfunctioning, can release air or materials unexpectedly, posing a significant hazard to the eyes. Wearing safety glasses ensures that the eyes are protected from harmful particles, chemical sprays, or any sudden release of air that could result in a dangerous situation.

While other forms of PPE play important roles in specific environments—such as gloves for hand protection, ear protection for noise reduction, and hard hats for head safety—the immediate threat to eye safety during pneumatic troubleshooting makes safety glasses the most critical piece of equipment in this context.
