What types of protective equipment should personnel wear when working with medical gas systems?

When working with medical gas systems, personnel should wear safety glasses, gloves, and appropriate respiratory protection to ensure their safety and minimize exposure to potential hazards. Medical gases can be under pressure and may pose risks such as leaks, which could lead to exposure to harmful substances or physical injuries.

Safety glasses protect the eyes from possible chemical splashes, flying debris, or pressure releases when handling or connecting equipment. Gloves provide hand protection against sharp objects, potential chemical exposure, or contamination. In certain situations, when there is a risk of inhalation of gases or vapors, respiratory protection becomes crucial to ensure that workers do not inhale harmful substances.

The other options do not address the necessary precautions for personnel engaged in this work. Simply wearing gloves and boots is insufficient to protect against the various risks associated with medical gas systems. Relying solely on safe practices without personal protective equipment overlooks the potential dangers present in the environment. Casual clothing does not provide the necessary protection and can expose individuals to hazards they might encounter while working with medical gases. Therefore, the comprehensive approach in the correct answer emphasizes the importance of using appropriate protective equipment to maintain a safe work environment.
