A magnetic resonance system and a safety control method for a magnetic resonance scan are provided. In the magnetic resonance scan, a local volume of a scanned subject is excited using a coupling coil, and the coupling coil is configured to receive a radio frequency (RF) excitation pulse from a body coil of the magnetic resonance system to generate an RF field for exciting the local volume. The safety control method includes: obtaining a whole-body SAR value monitored in real time, wherein the whole-body SAR value is obtained based on the body coil; determining a conversion coefficient during the magnetic resonance scan, and converting the current whole-body SAR value to a current local SAR value of the local volume based on the conversion coefficient; and determining a safety state of the magnetic resonance scan based on the current local SAR value.
