FIGURE 2—Hospitals exceeding Occupational Safety and Health Administration (OSHA) ethylene oxide (EtO) exposure limits in relation to OSHA regulatory pressure: (a) observed percentages of hospitals exceeding OSHA EtO limits, by year; (b) random effects regressionpredicted numbers of hospitals exceeding OSHA EtO limits, by year; (c) OSHA EtO regulatory enforcement activity, by year (number of inspections in which EtO standard was cited in hospitals, number of citations, and proposed penalties by year from OSHAs Integrated Management Information System).
Note. PEL = permissible exposure limit of 1 ppm time-weighted average over an 8-hour workshift; AL = action limit of 0.5 ppm time-weighted average over an 8-hour workshift; STEL = short-term excursion limit of 5 ppm time-weighted average over 15 minutes.
