Reactive Oxygen Species

Reactive Oxygen Species (ROS) are highly reactive oxygen-containing molecules, including superoxide anions (O₂⁻), hydrogen peroxide (H₂O₂), and hydroxyl radicals (•OH), produced during cellular metabolism or industrial processes. According to NIST chemical databases, ROS possess high oxidative potential, capable of damaging proteins, lipids, and DNA. In enterprise risk management (BCM), ROS are classified as occupational chemical hazards. Under the Taiwan Occupational Safety and Health Act (Article 30), companies must identify and control these hazards. Unlike acute toxins, ROS damage is often cumulative, requiring continuous monitoring rather than one-time assessment. This aligns with ISO 45001 Clause 6.1.2, which mandates the identification of hazards and risks to prevent occupational injuries and illnesses. Effective management requires integrating ROS exposure data into the overall OHSMS framework to ensure employee health and operational continuity.

Practical application follows a three-stage approach: First, 'Hazard Identification and Quantification' involves assessing chemical substances (e.g., disinfectants, cleaning agents) and process conditions (e.g., UV exposure, high temperatures) using OECD-compliant toxicological data. Second, 'Risk Control Measures' are implemented according to the hierarchy of controls: engineering controls (ventilation), administrative controls (rotation schedules), and PPE (respirators, gloves). Third, 'Health Surveillance and Performance Evaluation' tracks employee health indicators (e.g., lung function, oxidative stress biomarkers) against exposure levels. For instance, a chemical manufacturer implementing these steps can achieve a 30% reduction in occupational health-related claims and a 25% improvement in OHS own KPIs within the first year, meeting ISO 45001 Clause 9.1 requirements.

Taiwan enterprises face three primary challenges: First, 'Inadequate Hazard Identification'—many SMEs focus on acute toxicity while ignoring chronic ROS damage. The solution is to adopt NIST or OECD toxicological assessment tools for a comprehensive chemical inventory. Second, 'Low Employee Awareness'—workers often do not perceive the risks of colorless or odorless ROS. This requires structured OHS training as mandated by Taiwan's Occupational Safety and Health Act. Third, 'Lack of Data-Driven Monitoring'—without long-term health tracking, the risk-adjusted cost-benefit analysis is impossible. Companies should be closely closely monitored by occupational health professionals to establish baseline health data and track changes over time.
