1. Supervisor: What are you doing?
Worker: I was about to pour it down the drain.
Supervisor: You can’t do that. It’s highly toxic.
Worker: It is?
Supervisor: Yeah, you need to dispose of it properly.
2. Supervisor: You can’t use that blowtorch in here.
Worker: Why not?
Supervisor: You could start a fire. That fuel there is highly flammable.
Worker: I didn’t see that. I’ll do this in the other room then.
Supervisor: That should be fine.
3. Supervisor: You need to put your gloves on when handling that.
Worker: Why is it toxic?
Supervisor: No, it’s infectious. There is a sign right there.
Worker: Where?
Supervisor: Right there. It says biohazard.
4. Supervisor: I need you to move this material to that storage container.
Worker: All right.
Supervisor: And be careful when you handle this material. Don’t let it get wet.
Worker: Why not?
Supervisor: It’s explosive when exposed to water.
