Crush Hazard - Allow only one person to handle or operate the system at all times.
Operator injury may result if more than one person operates the system. Before working
inside the hazard area between the grips or fixtures, ensure that no other personnel can
operate the computer or any of the system controls.
Crush Hazard - Take care when installing or removing a specimen, assembly,
structure, or load string component.
Installation or removal of a specimen, assembly, structure, or load string component
involves working inside the hazard area between the grips or fixtures. Keep clear of the
jaws of a grip or fixture at all times. Keep clear of the hazard area between the grips or
fixtures during actuator or crosshead movement. Ensure that all actuator or crosshead
movements necessary for installation or removal are slow and, where possible, at a low
force setting.
Hazard - Press the Emergency Stop button whenever you consider that an unsafe
condition exists.
The Emergency Stop button removes hydraulic power or electrical drive from the testing
system and brings the hazardous elements of the system to a stop as quickly as possible.
It does not isolate the system from electrical power, other means are provided to
disconnect the electrical supply. Whenever you consider that safety may be
compromised, stop the test using the Emergency Stop button. Investigate and resolve the
situation that caused the use of the Emergency Stop button before you reset it.
Flying Debris Hazard - Make sure that test specimens are installed correctly in
grips or fixtures in order to eliminate stresses that can cause breakage of grip
jaws or fixture components.
Incorrect installation of test specimens creates stresses in grip jaws or fixture components
that can result in breakage of these components. The high energies involved can cause
the broken parts to be projected forcefully some distance from the test area. Install
specimens in the center of the grip jaws in line with the load path. Insert specimens into
the jaws by at least the amount recommended in your grip documentation. This amount
can vary between 66% to 100% insertion depth; refer to supplied instructions for your
specific grips. Use any centering and alignment devices provided.
Hazard - Protect electrical cables from damage and inadvertent disconnection.
The loss of controlling and feedback signals that can result from a disconnected or
damaged cable causes an open loop condition that may drive the actuator or crosshead
rapidly to its extremes of motion. Protect all electrical cables, particularly transducer
cables, from damage. Never route cables across the floor without protection, nor suspend
cables overhead under excessive strain. Use padding to avoid chafing where cables are
routed around corners or through wall openings.
