Psychological Health NEBOSH International General Certificate in Occupational Safety and Health Unit IG2 Learning Objectives Describe the health effects associated with exposure to noise and appropriate control measures. That couldn’t stop us. And we just went on before the dogs and we would look at them; and we’d go on before the water hoses and we would look at it, and we’d just go on singing “Over my head I see freedom in the air.” And then we would be thrown in the paddy wagons, and sometimes we were stacked in there like sardines in a can.
