Exploring on occupational health risk assessment of 2-butoxyethanol in a printing house

Objective To apply GBZ/T298-2017 "Guidelines for occupational health risk assessment of chemicals in the workplace" to conduct an occupational health risk assessment of 2-butoxyethanol exposure in a printing enterprise, in order to protect the laborers' health. Methods Conducted a worksite survey of occupational health include data collection, site investigation, determination 2-butoxyethanol in workplace air and raw and auxiliary material, determination 2-butoxyacetic acid in urine after shift from May 17 to 24, 2017, using the above results, conducting 2-butoxyethanol occupational health risk assessment. Results Concentrations of 2-butoxyethanol in the workplace air ranged from 1.2-30.8 mg/m3. Concentrations of 2-butoxyaceticacid in urine ranged from 35.5 mg/L to 563.3 mg/L. The printing shop with the highest concentration of air in the workplace in the enterprise was a medium risk for 2-butoxyethanol occupational health risks, and the binding workshop printer was a low risk for 2-butoxyethanol occupational health risks. The occupational health risk of 2-butoxyethanol in the print shop was medium. Conclusion Occupational health risks of 2-butoxyethanol for companies is medium, which should be included in the evaluation of routine occupational hazards and provide more targeted recommendations based on the action levels.
