Today I had a couple of guys working in an assisted living facility relamping the main lobby area. One employee set a step ladder on its side and went to shut off a circuit breaker. The two minutes that he was gone a lady in a cane with poor vision ran into the ladder and fell over. The lady, fortunately was alright after being checked out by the nurse at the facility. All I have to say is to be constantly aware of your surroundings and look out for other people. What you may not see as a hazard might be dangerous to others. Work safe.
