The best way to avoid danger from self-propelled units, such as cranes, dozers and trucks, is to keep your eyes open and stay out of the way. The operator does his best to not cause any accidents but with all the commotion on the construction site, it can become a challenge.
You must be especially careful when a vehicle is backing up. The operator should ask his foreman to direct him around the construction site, but sometimes that isn't possible. If nobody is directing him, the operator might not always see you, so you have to look out for him. Never take a chance and dart behind a vehicle that is backing up.
Riding On/In Vehicles
Don't ride on any vehicles except those intended to transport you on or between jobs. This includes the running board or drawbar of a unit, loaded trucks or the bucket of a bucket loader. Riding on the top of a load is especially dangerous. You may fall off if the load shifts or be crushed when going under low clearances. When riding in transport vehicles, keep your arms and legs inside to stay safe.
Walking Beside Vehicles
Don't walk alongside moving equipment. You can be killed or injured if the vehicle slides or turns, or if the load shifts. Do not walk under loads on cranes or hoists. Be especially careful not to touch the frame of a crane when there are power lines in the area. If the crane touches one of them, you'll be electrocuted. Remember, electricity can jump several feet, depending on voltage and weather conditions.
Not only vehicles, but moving equipment of any kind is dangerous. If, for example, you're working on portable staging, scaffolding or work platforms, stay off while it is being moved unless it is designated for you to be on it.
Stay ahead by not getting behind or along moving equipment. The more you are alert, the less chance you will have of getting hurt.
