Infrared lamps used during hair treatments should be operated at a distance of at least?

  1. 20 inches

  2. 25 inches

  3. 30 inches

  4. 35 inches

The correct answer is: 30 inches

Infrared lamps emit heat and can cause burns if used at a close distance. Therefore, it is important to operate them at a safe distance. 25, 30, and 35 inches are all reasonable distances, but 20 inches is too close and could potentially cause harm to the client's scalp. Therefore, C 30 inches is the correct answer.
