Pipeline projects back in Alaska, we always have a plan where to meet, course there it is about risk factor involving the element your dealing with.
I've seen it, where we had to leave for one site, and go to another to finish a day because of bears.
What else would you do if the weather is too inclement to continue working?
On the North Slope (Prudhoe Bay, Alaska) that is at about -40 below, and a 40 mile an hour cross wind. Course there are two people per rig, radios, and cell phones, on board.
Here in the desert, I've seen the 10" rain plan,,,draw a ten inch circle, if a drop of rain hits in it, call the job for the day (we have 331 days of sunshine).
Critical thinking will increase proportionally as the amount of risk surrounding a job rises.
