I think you are incorrect if you are saying that instrumentation is better inside a building. It is built to operate in specified temperature ranges and can be ordered to work in the harshest environments.

"Human Interdiction" is a nuclear term. It just means human interaction. Operating on delicate equipment requires reasonable ambient conditions. Process equipment does not. Maintenance and inspections happen in all temperatures in all conditions. They are fairly infrequent. Airplane maintenance is measured in hours/hour of flight time.
