Abstract

Objective: Describe the current situation of some working environment factors at toll stations on Phap Van - Cau Gie expressway. Methods: Cross-sectional descriptive study on working environment at 8 toll stations on the Phap Van-Cau Gie expressway from January 2023 to March 2023. Research indicators include microclimate, lighting, noise, toxic gas vapors (CO, CO₂, NO₂, SO₂, CH₂O, C₆H₆). Results: 100% of temperature measurement samples did not meet national standards. Humidity and wind speed both meet national standards. Light intensity meets national standards. 76.25% of noise measurement samples exceed national technical standards from 1-14.7 dBA. 45% of respiratory dust measurement samples and 40% of total dust measurement samples exceeded national standards from 0.29 - 0.71 mg/m³. 100% of samples measuring toxic CO gas exceeded national standards. All toxic gas samples CO₂, SO₂, NO₂, CH₂O, C₆H₆ meet national standards. Conclusion: Workers at road toll stations work regularly and continuously in specific working conditions, exposed to heat, humidity, noise, toxic gases, dust, and other unfavorable factors that directly affect the occupational health of workers.
