Someone needs prison time ... and those 'someones' are almost sure to carry briefcases, not tool belts.
And why is that?
Do you think a briefcase person was the one that decided to jury rig the fuse?
Apparently, the appropriate replacement fuse was not available (or there was trouble getting it to work properly), and the coworker had taped a renewable fuse link to the outside of the melted, nonrenewable fuse cartridge. The production worker removed the rigged fuse to inspect it, and then reinserted it into the fuse holder.
Regardless of any pressures from the bean counters those of us out in the field working with the tools need to be responsible for our own actions.
