without pulling and unplugging the cord. had previously worked machine operator an
electrical cable manufacturer and maintenance person for large university. Responsibility for safety was
assigned the engineer charge his particular section the lab.
The laboratory subjected the cables number different tests that simulate aging, lightning
strikes, and other conditions that would affect the high-voltage cables. Entry into the areas was through identically made doors built

All electrical testing was done inside several fenced-in areas constructed the laboratory. Each
area was surrounded six-foot high fence constructed light gauge wire fencing mounted to
two-by-four inch wood framing. The laboratory tested samples high-voltage electrical cables submitted by
electrical utilities, cable manufactures, and government agencies for quality-control purposes. Photos
