2.2 Magnet
Safety
A magnetic shielding system has been installed on each sidewall opposite of the magnet, and on
the rear wall of the mobile unit. The magnetic shielding system is extremely effective, and designed
to meet or exceed the Mobile MRI site plan requirements of the medical equipment manufacturer.
This system is proprietary.
1. All personnel with pacemakers, metal implants and neurostimulators should avoid entering
the exclusion zone of the magnetic field. The medical equipment manufacturer defines the
exclusion zone of the magnetic field.
2. Do not bring ferrous materials into the exclusion zone. These items may become
projectiles and cause serious injury, and / or property damage.
3. Watches can be damaged and credit cards can be erased if brought into the exclusion
zone.
2.3 Chemical
Safety
1. When working in the presence of liquid helium, make sure the work area is well ventilated.
2. Inhalation of helium or nitrogen can cause rapid suffocation. If any personnel inhale gas,
quickly move them to fresh air and seek medical attention at once.
3. The gases used in mobile MRI units to cool the magnet can cause severe frostbite. If
frostbite occurs, seek medical attention at once.
4. Liquid or gas can freeze air inside of vent lines. Check periodically to be certain that the
vent screen is open.
2.4 Electrical
Safety
Use and follow the appropriate Lockout/Tagout procedures as required by
OSHA Standard 1910.147 when performing maintenance or servicing any
electrical, hydraulic or pneumatic systems. See Appendix E for Lockout/Tagout
procedures.
Before connecting or disconnecting from shore power, it is imperative that the
shore power connections be moved to the “OFF” position. Failure to do this
can result in injury or death to the operator of the mobile unit.
It is the operator’s responsibility to verify that the shore power receptacle is of
the same type and voltage as the connection that is supplied by Oshkosh
Specialty Vehicles. Failure to do this can result in injury or death to the
operator of the mobile unit as well as irreparable damage to the mobile unit.
Always inspect the power cable, connectors, and fasteners prior to usage. If
during inspection, it is suspected that either internal or external damage has
occurred, have a certified electrician inspect and repair the damage before
using.
When working with the electrical system for the mobile unit. Follow the warnings and cautions listed
above.
