General Safety Practices: Hydraulic Power Units and
Safety
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.
Provide proper
hydraulic fluid
filtration
If the system is equipped with a non-MTS hydraulic power unit, ensure proper
filtration to the hydraulic distribution system and testing components. Particles
present in hydraulic fluid and cause erratic or poor system response.
Protect accumulators
from moving objects
Protect accumulators with supports or guards. Do not strike accumulators with
moving objects. This could cause the accumulator(s) to separate from the
manifold resulting in equipment damage and personal injury.
Do not exceed the
Maximum Supply
Pressure
For hydraulic grips and fixtures. make sure that the hydraulic supply pressure is
limited to the maximum pressure defined by the grip or fixture identification (ID)
tag.
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.
Use appropriately
sized fuses
Whenever you replace fuses for the system or supply, ensure that you use a fuse
that is appropriately sized and correctly installed. Undersized or oversized fuses
can result in cables that overheat and fuses that explode. Either instance creates a
fire hazard.
Provide adequate
lighting
Ensure adequate lighting to minimize the chance of operation errors, equipment
damage, and personal injury. You need to see what you are doing.
Provide means to
access out-of-reach
components
Make sure you can access system components that might be out of reach while
standing on the floor. For example, ladders or scaffolding might be required to
reach load cell connectors on tall load units.
Wear appropriate
personal protection
Wear eye protection when you work with high-pressure hydraulic fluid,
breakable specimens, or when anything characteristic to the specimen could
break apart.
Wear ear protection when you work near electric motors, pumps, or other devices
that generate high noise levels. Some systems can create sound pressure levels
that exceed 70 dbA during operation.
Wear appropriate personal protection equipment (gloves, boots, suits, respirators)
whenever you work with fluids, chemicals, or powders that can irritate or harm
the skin, respiratory system, or eyes.
