Question:

What is the difference between cable trench & cable tunnel?

Does underground cable trenches covered with cement structures need fire protection? What is the NFPA code for fire protection for underground cable trenches other than in cable tunnel or cable rooms?

Answer:

just as much as any video game or internet addiction i'd imagine
I usually knew before too long if my daughter needed changing. And I didn't need a heat detector. My nose was a pretty good indicator. Truly a waste of money. I don't think many children walk around with a wet or full diaper for a very long time unless their parents are neglectful.
