What is the correct procedure when replacing a bulb in most ophthalmic equipment?

1. Turn off the power and handle the new bulb effortlessly

2. Turn on the power to check bulb compatibility

3. Turn power off and handle new bulb with tissue or cloth

4. Wear gloves while replacing the bulb

The correct answer is: Turn power off and handle new bulb with tissue or cloth

When replacing a bulb in ophthalmic equipment, the correct procedure emphasizes the importance of turning off the power and handling the new bulb with tissue or cloth. This is critical for several reasons. First, turning off the power ensures safety for the technician and prevents any risk of electric shock while working with the equipment. Additionally, handling the new bulb with tissue or cloth helps to avoid oil and residue from fingers being transferred onto the glass surface of the bulb. Any such contaminants can affect the performance of the bulb and reduce its lifespan, as the oils can cause hot spots and lead to premature failure. Furthermore, maintaining the integrity of the bulb during installation is important for the optimal functioning of the ophthalmic equipment. This procedure protects not only the bulb but also the overall equipment, ensuring reliable operation in clinical settings. In contrast, other options involve either leaving the power on, which poses safety risks, or handling the bulb inappropriately, which could compromise its quality. Therefore, using the correct handling procedure is essential for maintaining proper equipment function and ensuring safety during the replacement process.
