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.
Handle chemicals safely
Whenever you use or handle chemicals (for example, cleaning fluids, hydraulic fluid, batteries, contaminated
parts, electrical fluids, and maintenance waste), refer to the appropriate MSDS documentation for that material
and determine the appropriate measures and equipment required to handle and use the chemical safely.
Ensure that the chemical is disposed of appropriately.
Know system interlocks
Interlock devices should always be used and properly adjusted. Interlock devices are designed to minimize
the chance of accidental damage to the test specimen or the equipment. Test all interlock devices for proper
operation immediately before a test. Do not disable or bypass any interlock devices as doing so could allow
hydraulic pressure to be applied regardless of the true interlock condition. The Reset/Override button is a
software function that can be used to temporarily override an interlock while attempting to gain control of the
system.
Know system limits
Never rely on system limits such as mechanical limits or software limits to protect you or any personnel.
System limits are designed to minimize the chance of accidental damage to test specimens or to equipment.
Test all limits for proper operation immediately before a test. Always use these limits and adjust them properly.
Do not disturb sensors
Do not bump, wiggle, adjust, disconnect, or otherwise disturb a sensor (such as an accelerometer or
extensometer) or its connecting cable when hydraulic pressure is applied.
Ensure secure cables
Do not change any cable connections when electrical power or hydraulic pressure is applied. If you attempt
to change a cable connection while the system is in operation, an open control loop condition can result. An
open control loop condition can cause a rapid, unexpected system response which can result in severe
personal injury, death, or damage to equipment. Also, ensure that all cables are connected after you make
any changes in the system configuration.
