    • On any type of job

    Correct Answer
    A. With tools that may cause flying particles
    Explanation
    When working with tools that may cause flying particles, it is important to wear eye protection. This is because these particles can cause serious damage to the eyes if they come into contact with them. Eye protection, such as safety goggles or glasses, can create a barrier between the eyes and the potential hazards, reducing the risk of injury. Therefore, wearing eye protection in such situations is crucial for ensuring safety and preventing any potential eye damage.

    Light is transmitted to the tip of a borescope by?

    • Fiber optics

    • An optical illusion bundle

    • A grounded extension cord

    • A directly magnified light source

    Correct Answer
    A. Fiber optics
    Explanation
    Light is transmitted to the tip of a borescope by fiber optics. Fiber optics is a technology that uses thin, flexible glass or plastic fibers to transmit light signals. These fibers are bundled together to form a cable, and when light is introduced at one end of the cable, it travels through the fibers and emerges at the other end, allowing for illumination at the tip of the borescope. This method provides a reliable and efficient way to transmit light in confined spaces, making it ideal for borescope applications.
