Administrative controls reduce exposure by reducing the time a person spends in noise: organising schedules so noisy work happens when only a few workers are present, notifying workers and others in advance so they can limit their exposure, keeping workers out of noisy areas their work does not require them to enter, providing quiet areas for rest breaks, and rotating jobs so workers move to quiet work before their daily exposure exceeds the standard. Where administrative controls are relied on, regular checks should confirm they are being complied with.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
