SAFETY PRECAUTIONS
WARNINGS:
CHAIR OPERATION BY QUALIFIED, TRAINED MEDICAL PERSONNEL ONLY
The chair is intended to be operated only by qualified, trained medical staff. Operation of chair by
unauthorized / untrained / lay people must be avoided.
USE CAUTION ON RAMPS
Control chair when traversing ramps. If a collision occurs, serious injury to patient, bystanders, or medical
personnel could result, as well as, damage to chair or medical facility could occur.
LOCK CASTERS BEFORE PATIENT EGRESS / INGRESS
Prior to patient egress / ingress, casters must be locked by depressing red tab completely down on either
left- or right-side brake pedal.
AVOID PINCH POINTS AND OTHER INJURIES
To prevent serious injury, ensure extremities of patient and bystanders are clear of all mechanical systems
when operating motors for lift and positioning functions.
To prevent pinch / crush injury, ensure extremities of patient and bystanders are clear of locking
mechanism when raising and lowering side rails.
To prevent patient strangulation, use approved hand pendant storage location when not in use. (see
PENDANT section)
BATTERY CAN EXPLODE DUE TO OFF-GASSING WHEN CHARGING
At end of charging process (or with overcharge conditions), battery can produce mixture of explosive gases
(including hydrogen and oxygen). Avoid exposing battery to open flames, cigarettes, sparks, and
incandescent materials.
Never charge battery in enclosed, unventilated spaces.
Do NOT store battery in sealed container. Store in fresh, well-ventilated area protected from direct sunlight
and heat sources.
Do NOT use water to extinguish battery fire. Use dry powder, foam CO
2
extinguisher.
USE CAUTION WHEN STORING OXYGEN CYLINDER UNDER CHAIR
To prevent severe gas leakage / rupture of compressed gas cylinder, when placing cylinder under chair,
ensure adequate clearance between cylinder and its attached gas equipment (i.e. regulator, gauges,
fittings, knobs) and all adjustable chair sections / features (i.e. seat, back, leg, rails, actuators).
To prevent fire / explosive hazard, do not leave chair (and stowed oxygen equipment) near heat source.
To prevent gas equipment damage during transport, ensure cylinder sets in cradle properly and strap
mechanisms are secured tightly. Chair is intended to accommodate up to an E-size cylinder (4-3/8
” outer
diameter x 25” length).
DO NOT PLACE EXCESSIVE WEIGHT ON ENDS
Position patient’s body weight uniformly over the patient surface. Use caution when shifting patient’s body
weight towards either end of the stretcher-chair. Excessive weight on either end of the device could cause
the stretcher-chair to become unstable.
Do not sit or stand on the ends of the stretcher-chair. Instruct patients to not stand on footrest during
egress / ingress.
Due to the unique nature of each patient’s body shape, caregiver should exercise sound judgment when
positioning patient on the device.
