Attention housekeeping staff before you begin your shifts on the surgical ward. Today there is a change to the cleaning protocol. We are switching to a new disinfectant solvent for mopping the floor. This new chemical is more effective.Against bacteria, but is also much stronger than what we used before. Therefore, it is mandatory that you wear the heavy duty rubber gloves instead of the standard latex ones to prevent skin irritation. The new gloves are available in the supply closet on the third floor.
