Damper System Operation Safety 23
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.
Provide test area
enclosure
Use protective enclosures and special laboratory layouts when you work with
hazardous test specimens (for example, brittle or fragmenting materials or
materials that are internally pressurized). Also use protective enclosures to limit
access to a running system.
Specimen temperature
changes
During cyclic testing, the specimen temperature can become hot enough to cause
burns. Wear personal protection equipment (gloves) when handling specimens.
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 servohydraulic
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 start the hydraulic power unit and 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.
Stay alert
Avoid long periods of work without adequate rest. In addition, avoid long periods
of repetitious, unvarying, or monotonous work because these conditions can
contribute to accidents and hazardous situations. If you are too familiar with the
work environment, it is easy to overlook potential hazards that exist in that
environment.
