I'm curious, if your alarm is functioning properly and would notify you if the storage device went out of temp and you have someone who would hear the alarm 24/7, why do we need to record the temp every 4 hours? Logically it dosen't make a lot of sense. We're not looking at the chart every 4 hours to see if it's working or if the temperature is being maintained. We depend on the alarm to tell us that. We document the temp seperately every morning and if the alarm dosen't sound then the temp range has been maintained. Oh, yeah, we do it too, we record the temp every four hours if the chart isn't working. Logic seldom overcomes inertia.
