Summary
A crew member received an electrical shock while stripping insulation during replacement motor work. The isolation omitted a space-heater supply in the test position, and a generic motor drawing had been used. The flash stresses equipment-specific drawings in permit-to-work and lockout/tagout procedures when determining isolation.
