Health and safety meetings and plans are part of a lot of work places. The idea is to reduce the unexpected - that is anticipate the things that can cause a safety issue. The picture below shows a safety issue that has caught me and recently gave an associate a problem.
The cobble beach makes for tricky footing as the cobbles shift while walking and can also be slippery. Hence, one gets preoccupied with watching carefully where to place a step. Hence, it can be easy to loose site of a large sharp log sticking at out at 5 feet 8 inches above the ground.
It is sort of a funny thing to receive a hard joust from a stationary spear or log. Its even funny when it happens to you, but it sure can hurt while at the same time making one feel very silly.
