Which statement is true about the installation of light switches in a machine room?

The statement regarding light switches in a machine room being easily accessible and near the entrance is correct because it aligns with safety and operational practices in elevator systems. Ensuring that light switches are readily accessible allows personnel to quickly illuminate the space when entering, which is crucial for their safety. A well-lit environment is necessary for performing inspections and maintenance tasks safely, as it reduces the risk of accidents or errors due to poor visibility. Furthermore, placing switches near the entrance promotes efficient operation, enabling technicians to control the lighting without having to navigate through the potentially complex machinery or equipment present in the room. This practice reflects industry standards aimed at enhancing safety and operational efficiency.

In contrast, other options do not align as well with safety protocols. For instance, installing switches outside the room might not provide immediate access in urgent situations, while unrestricted placement within the room could lead to accessibility issues or safety hazards. Additionally, setting a height requirement such as 24 inches does not necessarily address the need for accessibility or visibility in emergency scenarios.
