Far from being a source of risk, QTs have the potential to significantly enhance OSH outcomes through ultra-sensitive quantum sensors for environmental and health monitoring, secure quantum communication for protected data transmission, quantum simulations for ergonomic workplace design, and advanced predictive analytics for risk prevention. This paper explores how these innovations can revolutionize workplace safety and health infrastructure, especially in high-risk environments like mining, manufacturing, chemical plants, health monitoring, and military settings. Through strategic policy integration, safety-by-design principles, and interdisciplinary collaboration, the quantum revolution can be harnessed not only to redefine technological capabilities, but also to create safer, smarter, and more resilient occupational ecosystems. By proposing quantum-specific safety classifications, interdisciplinary oversight, and international collaboration, this paper calls for embedding safety-by-design principles into the core of quantum Research and Development (R and D). As quantum technologies become foundational to future industries, worker safety must advance in tandem framing quantum not merely as a technological revolution, but as a unique opportunity to reimagine the relationship between innovation and human well-being.</p>","PeriodicalId":43585,"journal":{"name":"Indian Journal of Occupational and Environmental Medicine","volume":"30 2","pages":"99-103"},"PeriodicalIF":0.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13411835/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148621939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
