Appreciate your reply. Thanks.In direct answer to your question. No. At least in Feeders.
Why? Well, define "should". Why wasn't the word "will" or "must" used?
To wit: We "should" do a lot of things........is that the same as has to, will or must?
Large pallets of bottled water are regularly stocked in our feeder operation.This water is regularly iced down in coolers). We had a global message not to drink while driving. Hands on the wheel(drink only when stopped at say your TA). This was questioned(message) and we were quickly told to disregard and drink when needed. The initial global message was sent in response to the in cab camera chaos. Seems the ORS's were/have been inundated with video reports. This led to discipline being started(coaching/talk with about distracted driving). There are ice and water dispensers sprinkled throughout the building. Fans all around including load/unload. Compliance? Seems to be. Is it a cake walk....hardly.
I read over some of the in-depth info from OSHA on heat. Acclimatization seems to be the focus. Taking a few days.
The "regulations" stated are nebulous enough to require more definitive wording....IMO.....to determine compliance.
