How do you refill patient's water pitchers in the hospital? We are no longer allowed to take their pitchers to the touch-free water machine. Currently, they have us using large styrofoam cups for each refill. Needless, to say we are making a lot of waste that is horrible for the enviornment. We were also told we could not use zip lock bags either. If anyone has a better system or has research that says there is nothing wrong with using zip locks, let me know please.
