Safety
Attention must be paid during planning to ensure that under emergency conditions in addition to
the marked emergency exits, non-marked entrances and exits to the control area can be used:
▪ Opening of exits and emergency routes during over- or underpressure conditions
▪ Labeling the control area at places that could be used in an emergency, e.g. adjacent win-
dows and escape routes.
2.2.5 Fire prevention
The MR system does not require any dedicated fire prevention. If fire prevention apparatus is to
be used at the installation site, the following notices should be heeded when planning installa-
tion:
▪ Many smoke detectors react to escaping cold helium, small amounts of which can be re-
leased during maintenance work on the magnet. To prevent inadvertent false alarms, detec-
tors that are heat triggered should be used instead.
▪ Heat detectors and sprinklers often require access for regular maintenance work. Attention
should be paid to ensure that these access points are not located in the area above the mag-
net, since maintenance is not possible there while the magnet is on field.
▪ To prevent damage to the magnet and to the MR system's control electronics due to false
alarms, Bruker BioSpin MRI recommends the use of so-called pre-action sprinklers.
2.2.6 Biological safety
In relation to the health and safety of employees and laboratory animals, we refer to compliance
with national specifications and regulations.
Repairs by Bruker BioSpin MRI can only be carried out after decontamination of equipment has
been demonstrated in writing and any damage to the health of Bruker BioSpin MRI employees
has been ruled out.
Appropriate aids, access and procedures that rule out any damage to the health of service per-
sonnel must therefore be provided for maintenance, service, and repair of the MR system.
▪ Measures and aids for cleaning and decontaminating hardware and accessories.
▪ If there a hazard category exists: Planning a physical separation between various hazard
areas for different parts of the MR system, e.g. technical room and its access in a non-haz-
ardous area.
2.2.7 Seismic safety
Installation in areas at seismic risk requires specific measures for making the MR system seis-
mically secure. These expansions are possible, but are not part of the scope of the MR system's
standard delivery. Please note in Chapter
Seismic safety standards [

2.2.8 Safety at work
For the general specifications for safety at work, we refer to compliance with the national regu-
lations.
Particular specifications for safety at work arise for the MR system in relation to:
