• 2The MHRA advises that it may be appropriate to have an MR responsible person for each MR system within an organisation. Duties include: • ensuring that adequate written safety procedures, ethical approvals, work instructions and emergency procedures (local rules) are issued to all concerned in consultation with the MRI safety expert

The MHRA recommends that all equipment that may be taken into the MR ENVIRONMENT is clearly labelled using these markings and where possible, the appropriate descriptive text should be used (see examples in Appendix 5 ). Users should always consult the conditions for safe use that accompany MR_CONDITIONAL

MRI safety zones are delineated areas within an MRI suite that help to manage the potential risks associated with powerful magnetic fields. The American College of Radiology (ACR) has classified these zones into four distinct levels, namely Zones I through IV.

The MHRA has received reports of staff, carers and patients suffering a temporary threshold shift, extended periods (including persistent, chronic) of ringing of the ears and tinnitus after exposure to MR noise without ear protection.

The use of MRI poses significant safety considerations for patients and staff and requires those working in MRI to have knowledge and understanding relating to the risks posed by static magnetic fields, time varying electromagnetic fields and biological effects.
