What protective gear is essential when installing HVAC metering devices?

When installing HVAC metering devices, the use of safety goggles and gloves is essential for protecting against hazards that may be encountered during the installation process. Safety goggles protect the eyes from debris, sharp objects, or harmful substances that may be present in the environment where HVAC systems are being installed. Gloves provide a barrier for the hands, shielding them from injuries such as cuts, abrasions, or exposure to chemicals that may be used during installation.

The other options do not provide adequate protection. Casual clothing and formal business attire do not offer any specific protection against physical or environmental hazards. Comfortable footwear, while important for overall comfort during long hours of work, does not address safety aspects necessary in an installation setting. Therefore, the correct choice emphasizes the importance of wearing suitable protective gear to ensure a safe work environment while handling HVAC metering devices.
