What are the six keys to avoiding slips and falls?
Look before stepping
Establish firm footing
Adjust to weather
Don't run, walk at a brisk pace
Stay off chutes, rollers, slides and belts
Don't skateboard and get caught on camera.
I think I posted in another thread about putting yourself in a situation where your integrity can be questioned, this is an example. Imagine if this person hurt himself legitimately say a week later on UPS time and out of nowhere this photo surfaced. Doing stuff like this while in uniform is a train wreck looking for a place to happen, it's a matter of when, not if.
