Environmental disinfectants should never be used on which of the following?

Using environmental disinfectants on items that will contact the patient is not advisable because these disinfectants often contain harsh chemicals that can cause skin irritation or chemical burns. Items that come into direct contact with patients, such as instruments or surfaces where procedures are performed, require high-level disinfection or sterilization methods that are safe for human contact. Environmental disinfectants are typically intended for surfaces that do not have direct contact with patients but are still important for maintaining a clean environment, such as medical equipment that does not touch the patient or processing room tables. Therefore, the focus on using appropriate and safe disinfection methods for patient contact items is critical in patient safety and infection control practices.
