Tools used to disinfect must be covered but not airtight. Which option describes appropriate containers?

• A. Jars or containers
• B. Paper bags
• C. Plastic wrap
• D. Aluminum foil

Answer: (A)

Disinfection relies on fully submerging tools in the solution for the required contact time, and the container you use should be able to be covered to prevent evaporation and splashes while not forming an airtight seal. Jars or containers are the appropriate choice because they are sturdy, washable vessels that can hold the liquid and be kept closed (to limit exposure and contamination) without sealing them airtight. Paper bags can’t hold liquid well, so immersion isn’t feasible. Plastic wrap and aluminum foil don’t provide a proper container for immersion and would either fail to hold liquid securely or create an airtight seal, which is unsafe for fumes and pressure.
