To add to what Jessica wrote, when coverage testing is done it is very important to test phones serviced by multiple carriers. In the building I worked in previously I found that Verizon phones had poor or no cell coverage in many interior rooms, while AT&T had good reception. If cell phones are used as the primary means of connection people should also be asked to set up wi-fi calling on their phones to help with reception issues. 

Also note that in the event of a wide-scale issue, such as a wider power outage, there can be a significant increase in the number of people using their cell phones leading to connection difficulties. I observed this issue first-hand when a power outage hit my university and I was unable to get any calls through on my cell phone

Best,

Mary

In addition to what everyone else has said here, I would also think they would want to test coverage EXTENSIVELY before they do. We had MANY weak and or dead zones for cell reception in the chemistry building in which I did my graduate work. One of the worst dead zones was the 1st level - where our main stockroom was. I am actually a little horrified when I hear that other campuses have chosen to remove the landlines from their buildings.

*Message sent from a system outside of UConn.*

[Bold my emphasis] EPA believes that, although cell phones are a useful means of communication, they should not be relied upon solely to satisfy this requirement. The Agency is therefore finalizing § 262.16(b)(8)(iv) and § 262.254 as proposed.

Thanks for this summary; I believe that was the situation the last time I looked into it and would be surprised if it changed. I ended up putting “No Smoking” signs on 12 chemical cabinets under fume hoods that are used as waste storage areas last year, even though indoor smoking has been banned on campus for at least 20 years...
