Contain small leaks
Do not use your fingers or hands to stop small leaks in pneumatic hoses. Substantial pressures can build up,
especially if the hole is small. These high pressures can cause the gas to penetrate your skin, causing painful
and dangerously infected wounds. Turn off the pneumatic supply and allow the pneumatic pressure to dissipate
before you remove and replace the hose or any pressurized component.
Stay clear of moving equipment/avoid crush points
Stay clear of mechanical linkages, connecting cables, and hoses that move because you can get pinched,
crushed, tangled, or dragged along with the equipment. High forces generated by the system can pinch, cut,
or crush anything in the path of the equipment and cause serious injury. Stay clear of any potential crush
points. Most test systems can produce sudden, high-force motion. Never assume that your reactions are fast
enough to allow you to escape injury when a system fails.
Know the causes of unexpected actuator motions
The high force and velocity capabilities of MTS actuators can be destructive and dangerous (especially if
actuator motion is unexpected). The most likely causes of unexpected actuator response are operator error
and equipment failure due to damage or abuse (such as broken, cut, or crushed cables and hoses; shorted
wires; overstressed feedback devices; and damaged components within the servocontrol loop). Eliminate
any condition that could cause unexpected actuator motion.
Do not use RF transmitters
Keep radio frequency (RF) transmitters away from the workstation computers, remote terminals, and electronics
consoles. Intense RF fields can cause erratic operation of the more sensitive circuits in the system.
Crush Zone
A crush zone exists between the T-slot base and crosshead which is highlighted in red in the following figure.
Keep clear of this area when the actuator is in motion. Press the Emergency Stop button on the frame-mounted
control to shut off power to the motor and stop actuator motion.
