This is an example on which reasonable people may differ.
If the issue is "unsafe practices" then punish those who are unsafe, rather than imposing artificial time constraints. The latter takes our collective eye off the ball, and leaves the pit stop observer looking at a stopwatch rather than at whatever goofy thing the crew might be doing. And it's THAT THING that's going to start a fire: Not the time they do or don't take to do it.
People inclined to be sloppy or inattentive will do so whether they are doing it quickly or slowly.
