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.
