Which of the following is a safety precaution when working with stage lighting?

Using protective gear is a crucial safety precaution when working with stage lighting due to the hazards associated with electrical equipment and heat generation. Stage lights can become extremely hot during operation, which poses a burn risk if touched without appropriate protection. Additionally, when working with lights, it's important to protect one's eyes from bright beams that can cause vision damage. Protective gear can include heat-resistant gloves, safety goggles, and appropriate clothing that minimizes exposure to potential hazards.

In contrast, while clear filters can be part of lighting setups, they do not inherently provide a safety benefit and can affect light quality. Dimming the lights might create a specific ambiance but does not address safety risks present during handling or installation. Blocking light from the audience is more about controlling the stage environment rather than ensuring the safety of individuals working with the equipment. Therefore, prioritizing protective gear is essential in maintaining a safe working environment in stagecraft.
