While sawing some boards for a project at home, Jim got sawdust in his eye. After playing with his eyelid for a bit, he was OK again. Then, without putting on his safety glasses, he cut more boards.
The next morning, he put a cup of water in the microwave to make tea. This always makes the cup handle hot, so he used an old, thin potholder to remove the cup. He slightly burned his fingers.
Once at work, he retrieved his DMM. He always meant to find the pouch that had come with it, but meanwhile just wrapped the test leads around it. Today, the leads got caught on something and when he yanked them the insulation separated at the probes. He was taping them up when his boss came by, gave him a lecture about getting shocked, and told him to throw those leads away. But Jim didn’t take this advice.
Jim still had the test leads from his first DMM (bought in 1995). Under the theory, “These test leads haven't shocked me yet,” he continued to use them. Later that day while working with Jim and holding the leads, coworker Gary received a serious shock.
Jim was right, “These test leads haven't shocked ME yet.”
There’s a lot of blame to be spread around in this particular scenario. Who do you think is at fault, and why?
