Protective Clothing in Endoscopy
Putting on and taking off personal protective equipment (PPE)
In endoscopy, employees are constantly exposed to various potentially biohazardous materials. Personal protective equipment is crucial to staff protection and infection control. But how has the use of personal protective equipment (PPE) changed since the start of the pandemic?
Endoscopic examinations can lead to spray from secretions, excretions and aerosol formation. Therefore, reliable, adequate respiratory protection for staff must be ensured during examinations. This requires a risk analysis and a hazard assessment of the individual examinations. Endoscopy, Occupational Health & Safety, and Hygiene usually work together to prepare these.
This article is about PPE in the SARS-CoV-2 pandemic. It is intended to illustrate how to put on and take off PPE. Depending on the hazard assessments, the individual items of PPE in endoscopy are:
There is no set way of putting on and taking off protective clothing. The various expert associations for occupational health & safety and hygiene provide different guidance on how to put on and take off PPE in a low-contamination manner. The various workplaces should define a concept for their facility after reading the recommendations, and constantly train employees on the procedure for putting on and taking off PPE. Staff must feel confident in handling PPE in order to prevent contamination and transmission.
The diagrams provided show a way of putting on and taking off PPE according to the US Centers for Disease Control and Prevention (CDC).
