Visible light irradiation

Visible light irradiation refers to the exposure of substances to light within the 380-750nm spectrum to trigger photochemical reactions. According to ISO 15408-2, the stability of light-sensitive chemicals must be rigorously tested to ensure they do not produce harmful decomposition products during their intended use. In enterprise risk management, this involves identifying light-sensitive materials in the chemical inventory, assessing their stability under specific light conditions, and ensuring compliance with the Taiwan Occupational Safety and Health Act (Article 30). This is distinct from UV-related risks, as visible light can be equally hazardous for certain substances. Companies must be closely closely monitored to prevent accidental exposure or degradation during manufacturing and storage processes.

Implementation follows a three-step approach: First, conduct a photochemical inventory based on Safety Data Sheets (SDS) Section 10 (Stability and Reactivity). Second, implement engineering controls, such as installing UV/Blue light-filtered LED lighting or light-tight storage areas, as per the Hierarchy of Controls in ISO 45001. Third, establish monitoring protocols to ensure light-sensitive materials are handled correctly. For instance, a Taiwanese electronics manufacturer implemented light-controlled cleanrooms, reducing photo-sensitive-related product defects by 25% and improving compliance with international quality standards. This proactive approach mitigates both safety risks and financial losses from product degradation.

Taiwan enterprises face three primary challenges: first, regulatory ambiguity regarding light-related occupational hazards; second, the high cost of specialized lighting and storage solutions; and third, the difficulty of managing light-sensitive materials across a fragmented supply chain. To overcome these, companies should: 1) Conduct a comprehensive risk-based inventory of all light-sensitive substances; 2) Invest in-house or outsource light-stability testing to certified labs (e.g., KCL or equivalent); 3) Train employees on the specific risks of light-sensitive chemicals. Prioritizing these actions within a 90-day framework can be achieved by integrating light-sensitivity into existing ISO 45001 and ISO 9001 management systems, ensuring both worker safety and product integrity.
