- Abstract: Objective To understand the situation of butanone exceeding the standard in the maintenance post of inkjet printer, and the measures and process of rectification in an electronic enterprise, and to provide reference for the management of over-standard posts in the same type of enterprises. Methods The relevant data were collected through on-site occupational health survey, process improvement and on-site detection. The rationality and feasibility of rectification of posts exceeding the standard were analyzed. Results Through many on-site process improvements, the posts were set up separately and effective protective facilities were added, and the concentration of butanone in the posts exceeding the standard was reduced from 894.2 mg/m3 (>5 OELs) to 4.4 mg/m3 (≤ 10% OELs), which was in line with the occupational exposure limit specified in the national standard. Conclusion The enterprise has successfully completed the rectification of the excessive concentration of butanone in the inkjet printer maintenance posts. It is an effective way to reduce the concentration of occupational hazards by setting up posts independently and adopting closed ventilation protection measures.
