Overview
Photobiological safety refers to the assessment and control of hazards to the eyes and skin from optical radiation sources such as ultraviolet (UV), visible light, infrared radiation, lasers, and LED lighting systems. With the increasing use of high-intensity lighting technologies in industries such as healthcare, manufacturing, electronics, lighting design, research laboratories, and construction, understanding the risks associated with optical radiation exposure has become essential.
This Photobiological Safety Training Course provides participants with a comprehensive understanding of the biological effects of optical radiation and the standards used to evaluate and mitigate associated hazards. The course introduces international safety standards such as IEC 62471, risk group classification of lamps and lighting systems, hazard measurement techniques, and proper safety controls.
Participants will learn how to identify photobiological hazards, conduct basic risk assessments, interpret safety classifications, and implement preventive measures to ensure compliance with occupational safety regulations and industry best practices.
