MTS Criterion Series 60 - Manual (Page 26)

On rare occasions, a fastener can fail even when it is correctly installed. Failure usually occurs during
torquing, but it can occur several days later. Failure of a fastener can result in a high velocity projectile.
Therefore, it is a good practice to avoid stationing personnel in line with or below assemblies that contain
large or long fasteners.
Practice good housekeeping
Keep the floors in the work area clean. Industrial chemicals, such as hydraulic fluid, that are 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 fluids 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. Use a cable cover or cable tray where cables are in traffic locations. Never walk on hoses or cables
or move heavy objects over them. Route hoses and cables away from areas that expose them to possible
damage.
Provide proper hydraulic fluid filtration
For hydraulic systems equipped with a non-MTS hydraulic power unit, make sure that hydraulic fluid
filtration is established to maintain fluid cleanliness standards as stated in the Hydraulic Fluid Care Manual
(see the System Documentation CD). Particles present in the hydraulic fluid can cause erratic or poor
system response.
Protect accumulators from moving objects
For systems equipped with accumulators, 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.
Record changes
If you change any operating procedure, write the change and the date of the change in the appropriate
manual.
Provide test area guards
Use protective guards such as cages, enclosures, and special laboratory layouts when you work with
hazardous test specimens (for example, brittle or fragmenting materials or materials that are internally
pressurized).
Do not exceed the Maximum Supply Pressure
For hydraulic systems and components, make sure that hydraulic supply pressure is limited to the maximum
pressure defined by the system operating limits. Read and review “System Operating Limits” for the system.
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.
