Frequency of Temperature and Relative Humidity Tracking
We have constant monitoring devices for temperature / relative humidity and are recording in our work/assembly areas.
Is there any form of standard on how often we should be recording this data? Or is it just enough to prove that we are in compliance at any given time?
|Expert Panel Responses|
There is no form on how often this should be done, but I would think the systems can continuously monitor the environmental conditions and those could have limit sensors identifying when the limits are exceeded.
This would also provide data of the compliance requirements.

If your monitors have the capability of recording the information so that you may produce it at any time then it is perfect. Also an automated system is much easier that having the operator or technician record temperature and humidity settings across a number of sensors/stations.

There's no standard that I'm aware of.
From a practical standpoint, it's very dependent on the physical characteristics of your facility. If, for instance, your facility is subject to rapid changes due to opening/closing of dock doors, then a faster rate of recording may be beneficial to you to understand the impact of the transients. In a situation like that, I have used intervals between 1 minute and 5 minutes between readings.
Bottom line, these days data storage and transmission is so cheap that there is little penalty for acquiring more data, however we should be careful to not be taking data that we will never use, or taking so much data that analysis becomes burdensome.
