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.
