Would installing the IPC be a “non contact work are exempted” task?
No. Non contact is things like infrared scans or using a non contact voltage detector. It’s just that OSHA separates construction (including “major maintenance” where you essentially rebuild something), operations, and maintenance. Construction has no limitation. Operating tasks have no limitations so long as you wear proper PPE. It includes operating disconnects, using controls, and so forth. It would include an activity like racking a switchgear breaker in or out, or plugging in or unplugging something. It does not include say putting a wire into a mechanical terminal and tightening it. Operations are not restricted so long as proper PPE is used. Only maintenance activities are prohibited without justification. So this is the hard part...is the activity maintenance, construction, or operations?
