SAFETY PRECAUTIONS 1

1-2
150832-639 Operating Manual Safety Precautions
WARNING – PERSONAL INJURY HAZARD:
WARNING – INSTABILITY HAZARD:
WARNING – PINCHING AND TIPPING HAZARD:
Failure to keep the patient properly secured with the patient safety straps at all times could result in
death or serious injury.
The floor locks must be engaged at all times when a patient is on the table. Failure to engage the floor
locks before placing a patient on the table or disengaging the floor locks while a patient is on the table
could result in the table rolling unexpectedly during the procedure.
Keep hands and feet clear of the unloading platform and the table base when unloading the table.
Serious personal injury could result.
Section 4.1, Steps 1-6 in "Operating Table" must be executed before patient is transfered to the table.
Execution of Steps 1-6 with the patient on the table could result in injury to both the patient and the
operating room staff.
Healthcare professionals must ensure patients are positioned and monitored so as to prevent
compromising respiration, nerve pathways or circulation.
When installing any table accessory, check for correct attachment and tighten securely (if appropriate).
Do not use a worn or damaged accessory. Before using any accessory, ensure it has been installed
properly.
Patient must be secured to the table in accordance with recommended positioning practices.
Unanticipated patient or table movement could result in death or serious injury.
When cleaning/disinfecting table, do not use phenolics which may cause patient skin burns if
inadequately rinsed off, or alcohol, which does not have sufficient cleaning/disinfecting properties.
The table leg section is designed to support the patient legs. Do not put upper body weight on the leg
section.
If the integrity of the external protective ground installation or arrangement is in doubt, operate the table
from its internal power source.
If an antistatic path is necessary, STERIS recommends antistatic pads (specifically developed for this
table) in direct contact with the patient. Table must also be positioned on antistatic floor or connected to
equalization device (equipotential connector).
Do not remove table leg section if patient is not properly positioned. Patient's torso and buttocks must
be firmly held in place by table back and seat sections and legs supported by leg supports.
Possible patient or user injury, as well as table or accessory failure, may result from using STERIS table
accessories for other than their stated purpose – or from using accessories manufactured and sold by
other companies on STERIS surgical tables.
Patient injury may result if the operator of this table is not completely familiar with the controls for patient
positioning and table operation.

Safety Precautions Operating Manual 150832-639
WARNING – PERSONAL INJURY AND/OR EQUIPMENT DAMAGE HAZARD:
WARNING – INFECTION HAZARD:
Repairs and adjustments to this equipment must be made only by STERIS or STERIS-trained service
personnel. Maintenance performed by unqualified personnel or installation of unauthorized parts could
cause personal injury, result in improper equipment performance, invalidate the warranty, or result in
costly damage. Contact STERIS regarding service options.
Regularly scheduled preventive maintenance is required for safe and reliable operation of this
equipment. Contact STERIS to schedule preventive maintenance.
Table is factory set to operate at a certain voltage. Use of any other power supply could result in serious
personal injury or table damage.
Use of this table in the presence of flammable anesthetics could result in serious personal injury or table
damage.
Placing a patient whose weight exceeds maximum patient weight limit (patient in normal orientation) of
1100 lb (499 kg) without patient posturing or tabletop slide (except raise/lower), 1000 lb (454 kg) with
patient posturing (except tabletop slide), or 600 lb (272 kg) with full patient posturing (including
tabletop slide) could result in injury to the patient and the operating room staff, and serious equipment
damage.
Failure to perform periodic inspections of the table could result in serious personal injury or equipment
damage.
The Auto Limit Sensors (ALS) System suggested alternative tabletop movement does not take into
account the type of surgery that may be in process or the environment (e.g., other equipment close by)
and might not be compatible with the surgical procedure. To avoid an action that could result in death or
serious injury to the patient and the operating room staff, and/or serious equipment damage, completely
evaluate the feasibility of the suggestion.
ALS System is not active during Backup Control. Ensure proper tabletop movements to prevent patient/
staff injury and/or equipment damage.
During Backup Control, tabletop functions are available even if table floor locks are NOT engaged.
LOCK table before moving tabletop or transferring patient.
Use of accessories, transducers or cables with this table, other than those specified, may result in
increased emissions or decreased immunity of the table.
Do not store items on table base. Doing so may result in equipment damage or inadvertent tabletop
movement placing the patient and/or user at risk of injury.
Failure to keep all personnel and equipment clear of the table before actuating any inertia-driven or
power-driven movement could result in table damage and/or personal injury.
To protect against aerosols being reflected from potentially contaminated surfaces, wear rubber or
plastic gloves, masks and eye protection, and follow OSHA blood-borne pathogens standards when
cleaning.
When cleaning/disinfecting table, do not use alcohol as it does not have sufficient cleaning/disinfection
properties.

150832-639 Operating Manual Safety Precautions
WARNING – DISPOSAL HAZARD:
CAUTION – POSSIBLE EQUIPMENT DAM AGE:
REMEMBER – POSSIBLE TIME DELAY:
This product contains materials which may require disposal through appropriately licensed and
permitted hazardous waste management firms.
When moving the table to or from point of use, roll it carefully at moderate speed and only over smooth
floors. Maximum floor clearance is 1/4" (6.4 mm). Avoid door and elevator jambs, and obstructions
greater than 1/4" (6.4 mm). If necessary, lift table over obstructions, onto trucks, etc. Lift table evenly
and only by the table base. DO NOT transport articles (including accessories) on top of the table, and
DO NOT use a forklift to move the uncrated table.
Hang the hand control from side rail of the table when not in use to avoid possible damage to the
control.
When cleaning/disinfecting table, thoroughly read the cleaning fluid directions for use and follow all
directions and cautions as shown.
Do not spray cleaning fluid into electric receptacles and avoid spraying directly on emergency backup
buttons or into clearance space. Spray or drippage may settle onto electric circuits inside table causing
corrosion and loss of function.
Cleaning procedures requiring articulation of the table should be performed only by persons familiar
with table operation.
Route the hand control cord clear of any pinch points where cord could be damaged.
Use of incorrect hydraulic oil may severely damage the table and/or cause malfunction. Contact STERIS
for proper hydraulic oil.
After performing cleaning procedures, ensure pads, tabletop and X-ray tops are completely dry before
reinstalling. Moisture trapped between pads and X-ray tops may contribute to equipment damage, such
as X-ray top warpage.
Appropriate components of this surgical table have been tested and found in compliance with IEC
