security lighting, nonrevenue transit facilities


Security lighting may be one of the most cost-effective and universally accepted security measures any organization can use to improve its security posture. Effective security lighting both deters criminal behavior and may enhance safety, thereby, reducing overall risk and accidents. Properly designed
and planned security lighting can create a sense of openness and a feeling of security for employees and staff at transit nonrevenue facilities. Security lighting aids the ability to observe and monitor movements through the facilities and supports the fundamental principles of crime prevention through environmental design (CPTED). Throughout this Recommended Practice, Occupational Safety and Health Administration (OSHA) safety lighting standards and security industry lighting best practices were applied. Where OSHA foot-candle measurements for safety lighting were higher than security industry lighting measurements, the OSHA measurements were used. Where security industry lighting measurements were higher than OSHA safety lighting standards, the security industry lighting measurements were used.
