Q: A state surveyor cited us for not doing a monthly fire pump automatic transfer switch (ATS) test. We are doing a weekly churn test and an annual fire pump flow test that includes switching over the ATS. I was not aware that this had to be done monthly.
A: Yes… NFPA 110-1999, section 6-4.5 requires all transfer switches in Level I and Level II systems (hospitals typically have Level I systems) to be tested monthly. The state surveyor is correct. I find that it is not uncommon for some hospitals to overlook the ATS serving the fire pump. I guess they don’t always see that it is part of the Level I emergency power supply system. Out-of-site is out-of-mind!
