My alarm on my iPhone didn't go off this morning, and it's not the first time. It does itRandomly every now and then but it sometimes works. I always keep the sound on, so what is the problem?
it's impossible;e to know unless you get a co2 detector they can be rented at home depot,Lowe's or any tool rental outlet.this is a very serious issue and should be tested asap.good luck
Try chemical companies. It is not a common, everyday chemical.
