Busses in high temperature weather
Quick one for the collective, what are the rules or more importantly the additional safety aspects that Bus drivers and Bus companies should be doing if temperatures get unusually hot for your area.
Background Irish Bus driver, our temperature normally doesn't get higher than low 20's degrees C. (Less than 73f) And a similar bus driver problem world wide, can't drink too much because lack of toilet facilities. AC doesn't really exist in most of the buses for cab area. No known guidelines from company or national transport because high temperature isn't common in Ireland.
So any guidance would be appreciated.
