Warm clothes can only go so far, you have to still be able to move. Workers need a heat source to replenish themselves, not just to bundle up. To wear all the necessary clothing to keep myself warm for a 45 minute walk adds 15 minutes on to the walk because of how much it bogs me down.
Warm can be done easily enough with the right clothing, but yeah, safety is another matter.
