NIOSH survey findings indicate that healthcare workers who disinfect medical and dental devices do not always use precautionary measures to protect themselves from exposure to high-level disinfectants (HLDs). According to NIOSH, some of these chemicals—including glutaraldehyde, orthophthaldehyde, peracetic acid, and hydrogen peroxide—are respiratory and skin irritants and sensitizers, and workers who use HLDs are at risk of exposure. Results of the study were recently published in Infection Control and Hospital Epidemiology. The authors conclude that the findings highlight the importance of improved employer and worker training and education regarding these hazards.
