I'm impressed by the intelligence represented by this decision. As climate change heats up we'll all end up learning new methods for working in extreme heat, but in regions where there is no training and equipment it's thinking like this that saves lives.
I worked in a glue factory on night shift for three months in a harsh winter where internal temperatures got over 90, and have seen the special procedures and equipment they use on summer days when it gets over 112. It takes training in awareness of self and others, PPE such as chillled wetting vests and forearm bands, hydration measures, building infrastructure, and management techniques all in place to work over 100 degrees.
Thank you for working safe, Paizo.
