Wake County Certified Pool Operator (CPO) Practice Test

The appropriate amount of lighting for the area surrounding the pool's filtration system is critical for ensuring safe and efficient maintenance. A level of 10 foot candles is generally recommended, as this provides sufficient illumination to navigate the space safely and effectively perform maintenance tasks without straining the eyes or creating hazardous conditions.

This lighting level allows operators to clearly see the components of the filtration system, identify any potential issues, and carry out necessary repairs or adjustments. Adequate lighting also helps in ensuring safety, as operators can avoid slips, trips, and falls while working around equipment that may have power sources or water present.

Having lower levels of lighting, such as 5 foot candles, may not provide the visibility needed for detailed inspections or repairs. Conversely, excessively high levels of lighting, such as 20 or 30 foot candles, could lead to glare or other visual discomfort, making it hard to work effectively. Therefore, 10 foot candles strikes a balance, ensuring that the area is sufficiently illuminated for safe and effective maintenance of the pool's filtration system.
