There are a number of regulations regarding exposure time vs warmup/recorvery time based on how cold it is, these are just made up numbers for an example but if it is -30 then maximum exposure is 45 minutes with 20 minutes in a warm environment to recover, if it is -40 then maximum exposure is 25 minutes and so on. How well companies follow that is another matter.
You also have situations where some tasks can't be done below a certain tempurature, by code structural welds can't be done below -18 as there is a risk that the metal doesn't heat up enough and you don't get a proper bond.
