General Safety Practices
Multi-Pump Control Manager Safety
11
Have first aid available
Accidents can happen even when you are careful. Arrange your operator
schedules so that a properly trained person is always close by to render first aid.
In addition, ensure that local emergency contact information is posted clearly and
in sight of the system operator.
Know potential crush
and pinch points
Be aware of potential crush and pinch points on your system and keep personnel
and equipment clear of these areas.
Remember, when hydraulic power is interrupted on a servohydraulic system, it is
likely that stored accumulator pressure will persist for some time within the
system. In addition, it is likely that as stored energy dissipates, gravity will cause
portions of the system to move.
Be aware of
component movement
with hydraulics off
The actuator rod can also drift down when hydraulics are turned off hitting
anything in its path. This uncommanded movement is because of oil movement
between the pressure/return ports and oil blow by across the piston hub. Be aware
that this can happen and clear the area around the actuator rod when hydraulics
are turned off.
Know electrical
hazards
When the system electrical power is turned on, minimize the potential for
electrical shock hazards. Wear clothing and use tools that are properly insulated
for electrical work. Avoid contact with exposed wiring or switch contacts.
Whenever possible, turn off electrical power when you work on or in proximity
to any electrical system component. Observe the same precautions as those given
for any other high-voltage machinery.
Make sure that all electrical components are adequately grounded. Grounds must
remain connected and undisturbed at all times.
Keep bystanders
safely away
Keep bystanders at a safe distance from all equipment. Never allow bystanders to
touch specimens or equipment while the test is running.
Wear proper clothing
Do not wear neckties, shop aprons, loose clothing or jewelry, or long hair that
could get caught in equipment and result in an injury. Remove loose clothing or
jewelry and restrain long hair.
Practice good
housekeeping
Keep the floors in the work area clean. Hydraulic fluid that is spilled on any type
of floor can result in a dangerous, slippery surface. Do not leave tools, fixtures,
or other items not specific to the test, lying about on the floor, system, or decking.
Protect hoses and
cables
Protect electrical cables from spilled hydraulic fluid and from excessive
temperatures that can cause the cables to harden and eventually fail. Ensure that
all cables have appropriate strain relief devices installed at the cable and near the
connector plug. Do not use the connector plug as a strain relief.
Protect all system hoses and cables from sharp or abrasive objects that can cause
the hose or cable to fail. Never walk on hoses or cables or move heavy objects
over them. Consider hydraulic distribution system layout and route hoses and
cables away from areas that expose them to possible damage.
Do not disable safety
devices
Your system may have active or passive safety devices installed to prevent
system operation if the device indicates an unsafe condition. Do not disable such
devices as it may result in unexpected system motion.
