Rotating Machinery Hazard - Disconnect power supplies before removing the
covers to rotating machinery.
Disconnect equipment from all power supplies before removing any cover which gives
access to rotating machinery. Do not reconnect any power supply while the covers are
removed unless you are specifically instructed to do so in the manual. If the equipment
needs to be operated to perform maintenance tasks with the covers removed, ensure that
all loose clothing, long hair, etc. is tied back. Refit covers as soon as possible.
Hazard - Shut down the hydraulic power supply and discharge hydraulic pressure
before disconnection of any hydraulic fluid coupling.
Do not disconnect any hydraulic coupling without first shutting down the hydraulic
power supply and discharging stored pressure to zero. Tie down or otherwise secure all
pressurized hoses to prevent movement during system operation and to prevent the hose
from whipping about in the event of a rupture.
Hazard - Shut off the supply of compressed gas and discharge residual gas
pressure before you disconnect any compressed gas coupling.
Do not release gas connections without first disconnecting the gas supply and
discharging any residual pressure to zero.
Explosion Hazard - Wear eye protection and use protective shields or screens
whenever any possibility exists of a hazard from the failure of a specimen,
assembly or structure under test.
Wear eye protection and use protective shields or screens whenever a risk of injury to
operators and observers exists from the failure of a test specimen, assembly or structure,
particularly where explosive disintegration may occur. Due to the wide range of
specimen materials, assemblies or structures that may be tested, any hazard resulting
from the failure of a test specimen, assembly or structure is entirely the responsibility of
the owner and the user of the equipment.
Hazard - Ensure components of the load string are correctly pre-loaded to
minimize the risk of fatigue failure.
Dynamic systems, especially where load reversals through zero are occurring, are at risk
of fatigue cracks developing if components of the load string are not correctly pre-loaded
to one another. Apply the specified torque to all load string fasteners and the correct
setting to wedge washers or spiral washers. Visually inspect highly stressed components
such as grips and threaded adapters prior to every fatigue test for signs of wear or fatigue
damage.
