Are heatstroke prevention, cooling, cold protection and moisture-proof facilities not occupational disease protection facilities correct?

Not correct. Occupational disease protection facilities are the general name of equipment, facilities, devices and structures to protect workers' health. According to their different functions, occupational disease protection facilities mainly include dustproof, antivirus, noise prevention, vibration prevention, heatstroke prevention and cooling, and it is wrong to say that heatstroke prevention and cooling, cold protection and moisture-proof facilities are not occupational disease protection facilities.
