What safety measure is crucial when working with pressurized systems?

When working with pressurized systems, properly using personal protective equipment (PPE) is a critical safety measure. Pressurized systems can pose significant hazards, including high-pressure leaks, explosive releases of gas, or burns from hot surfaces. PPE is designed to protect workers from these risks by providing necessary barriers against potential injury. This can include items like safety goggles, gloves, face shields, and protective clothing, which help safeguard against exposure to harmful substances and physical injuries. By wearing appropriate PPE, workers can mitigate the risks associated with sudden pressure releases and other dangers inherent in pressurized environments, ensuring they are better protected during the execution of their tasks.

While maintaining equipment regularly is also important for safety, it primarily helps in preventing malfunctions rather than protecting personal safety directly. Ignoring warning signs and performing tasks without supervision directly increase the risks associated with working in such environments and are not safe practices.
