Update on occupational dermatitis: reviewing toxic substances from OSHA standards.

Occupational dermatitis (OD) is an inflammatory skin disease stemming from exposure to specific substances within a work setting. As the second most prevalent occupational health concern in 2020, affecting 1.8 per 10,000 workers, OD poses a significant challenge to workforce well-being and imposes a substantial economic burden through lost wages, decreased productivity, and increased healthcare spending. Dermatologists emerge as pivotal figures in recognizing risk factors and delivering essential care to individuals with OD. This review focuses on chemical hazards and toxic substances regulated by the Occupational Safety and Health Administration across general industry, maritime, and construction sectors. It explores the background of each hazard, pathophysiology to dermatitis, and human cases reported between 2017 and 2023 for formaldehyde, chromium, vinyl chloride, and cadmium.
