Certified Endoscope Reprocessor (CER) Practice Test 2025 – Complete Exam Prep

Manual high-level disinfection indeed carries a higher risk of chemical exposure compared to using an Automated Endoscope Reprocessor (AER). This is largely due to the hands-on nature of manual processes where workers are in direct contact with hazardous chemicals, increasing the likelihood of spills, splashes, or inhalation of fumes.

In contrast, AERs are designed to minimize human intervention during the disinfection process, thereby reducing the potential for exposure. The machines automate the cleaning and disinfection cycles, which limits the amount of time staff spend handling chemicals and helps to contain any chemical spills or vapors. Furthermore, AERs often feature built-in safety mechanisms and containment systems that protect the operator from exposure to harmful substances.

While both methods involve the use of chemicals necessary for high-level disinfection, the automated approach significantly mitigates risks associated with manual handling and increases overall safety for healthcare professionals involved in the reprocessing of endoscopes.
