Provide adequate lighting
Ensure adequate lighting to minimize the chance of operation errors, equipment damage, and personal
injury. You need to see what you are doing.
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.
