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.
