The Injury Triangle

Another one of those tragic stories, this one from Kimmes Oil And Tire in northern Minnesota:

When officers and rescue personnel arrived at the scene they learned that a 21-year-old employee had been servicing a Kenworth Dump Truck on the property when the truck moved and rolled over him. The man died at the scene from his injuries.

Police are continuing to investigate the incident, but say preliminary indications are that this was a “tragic accident.” 

The Injury Triangle© is such a simple model of what it takes to get hurt: 
Person + Object + Energy

Here’s a case when person and the object are stunningly obvious. As to where the energy came from, investigators will figure that out: was it an earthquake…..or something more commonplace, like the energy of the truck rolling while a tire is being removed.

Anything is possible, but this one happened at a tire business – in Minnesota. 


The better use of the The Injury Triangle© is before – not after – the event. 

For example, if you’re going to change the tires on a dump truck, you want to keep yourself out of harm’s way. If you have to place yourself in harm’s way, do something to decrease the odds that harm comes your way.

Such as setting the parking break and chocking the tires. 

Doing that won’t guarantee being safe, but it will dramatically increase the likelihood that you’ll go home alive and well at the end of the day.
