Did you know that machinery can be very, very  dangerous for us humans and animals. Machinery is what you drive in everyday and it has an engine that will run on petrol or diesel. What you drive to school in everyday is a machine. People have been run over before by machines. That's why we have to have safety around these dangerous Physical Machines that are used in Forestry to Tear down Trees.

Firstly, if you stand behind a car it could come back and hurt you very badly, you could end up in hospital. You could even die to the simple mistake. That is why you  Gotta think Before you act. It Just might give you a second chance at life. Thousands of people a year get killed in car crashes and that is a machine.  Forestry workers have been run over by the forestry equipment. Like heavy duty logging trucks and machines that pick up the logs and saw them down.

Secondly people wear orange things that glow in the lights of cars. It is for safety, so at night they don't get hit while working at the site.

Finally, did you know that people can only move houses through towns at night time? So it is very important to think about safety for the House Movers.

Safety is about keeping yourself good and safe from dangerous equipment. We can keep ourselves safe if we don't take risks. Don't listen to people that want you to do dangerous things. Stay safe around large machinery!
