What should a worker always wear when setting up and adjusting studio lights?

When setting up and adjusting studio lights, wearing eye protection and gloves is essential for safety. Studio lights can generate significant heat and brightness, which could lead to eye damage if proper protection is not worn. The bright output can cause glare or even temporary blindness, so using eye protection such as goggles or safety glasses is crucial to safeguard vision.

Gloves are important as well because studio lights can reach high temperatures, and handling them without protection can result in burns or skin irritation. Protective gloves specifically designed for handling hot equipment will help minimize these risks.

While ear protection, protective clothing, and heat-resistant gear can be important in specific circumstances, the primary hazards associated with adjusting studio lights center around exposure to intense light and heat. Therefore, eye protection and gloves are the best choices to ensure safety in this particular situation.
