Answer:

Article 1.4.9 of the Philippine Electrical Code (PEC) states that electrical installations in medical and healthcare facilities must be designed and installed to provide adequate lighting. This is an important safety requirement that helps to ensure the effective operation of medical equipment, the safety of patients and staff, and the overall quality of care provided in these facilities.

Adequate lighting is especially important in medical and healthcare facilities, where visual acuity and precision are critical. Proper lighting can help medical personnel to accurately diagnose and treat patients, and can also help to prevent accidents and errors due to poor visibility.

The PEC provides specific guidelines for lighting design and installation in medical and healthcare facilities, including minimum illumination levels for various areas and types of equipment. These guidelines may vary depending on the specific type of facility and the types of activities performed in different areas.

In addition to providing adequate lighting, electrical installations in medical and healthcare facilities must also comply with other safety and quality standards, including those related to grounding and bonding, electrical system design, and equipment maintenance and testing.

Overall, Article 1.4.9 of the PEC emphasizes the importance of adequate lighting as an essential safety feature in medical and healthcare facilities, and provides guidelines for ensuring that lighting installations are designed and installed to meet the unique needs of these facilities.
