Injection hazard demonstration

BlastOne’s Master Technician, Kerry Cooper, demonstrates a simulated high pressure injection incident and discusses an action plan should it occur


So, the airless gun and tip that we talked about before has the capacity to inject me.
So, to give you an indication of just how powerful that is; this particular airless pump that we’re using today for this topcoat polyurethane and this is very thin.

What we’ve done is we’ve put a piece of meat on the wall up here to show you how
easy this is to penetrate your skin.

So, say for example, I had that up against me or I bumped myself and I pulled the trigger. That’s this sort of injection I’m talking about.

So, basically, what that’s done is that’s gone way into that piece of meat. So, that is the same configuration as your skin. So, if I do it again, there you go. You see it’s got a fester and then the paint is running out. Fine! But there’s also a significant amount of paint that’s actually penetrated that piece of meat.

So, it fills it up. It loads it up with the hydraulic capacity of the material and of course, it’s shoved it straight into that piece of meat.

So, this piece of meat, guys, is exactly the same as your skin. So, if you’re not careful and you pull that trigger, you can see here how it’s cascading out of the hole. But as I push it, more paint runs out. That’s exactly what will happen to you if you’re not very, very, very, very careful.

So, the tip itself is a dangerous piece of equipment. Always put the safety on when you’re not using it. Always keep it clean.

So, we can see that the backing washer is sealing onto the tip appropriately and periodically during the day. I’ll always wash this.
