This photo is out of focus and shows motion blur. But, it got a dangerous working condition fixed. Most of us have cell phones that have cameras in them. When you see a dangerous working condition use that phone for more than calling your boss. Take a picture of the problem.
Sometimes problems are temporarily cleaned up by the time a manager is able to come over and investigate a situation, only to return again later. In this case contractor employees, one of whom is pictured, were doing work that intermittently blocked emergency egress of an SJSU building. By taking a picture I was able to to send it from my phone in an e-mail to head of risk management at SJSU. The photo may not win any awards, but it sure got the job done. The problem was immediately resolved.
