    Why workplaces rely on Perry Weather for OSHA heat regulation compliance

    “As an EHS manager with GridWorks, I have a ton of things to do. I have paperwork, I have meetings, I have reports, plus I have to watch over the personnel on our site, plus my personnel. Perry Weather makes my job easy because I don’t have to constantly monitor the weather to see if we have storms or extreme heat for the day. Any weather event happens. It notifies me. That way I can take action.”
