A year or so ago a major waste company placed 12 street cleaners, wearing yellow hi viz coats in a busy out of town shopping complex and asked shoppers coming out how many they remembered seeing. The average the shoppers reported seeing was four. A month later they repeated the test with 12 workers in shocking pink hi viz coats. The average the shoppers reported seeing was nine.
A few weeks ago I happened to be home when an employee of my electricity supplier called to read the meter. I noticed that he was wearing full safety boots. After some questioning and examination I discovered that the boots he was wearing were a heavy 200j toecap, steel mid-sole boot with s3 oil and chemical resistance. According to the personal pedometer the man was carrying he reported walking 20+ miles per day.
