High/Low Temperature Hazard - Wear protective clothing when handling
equipment at extremes of temperature.
Materials testing is often carried out at non-ambient temperatures using ovens,
furnaces or cryogenic chambers. Extreme temperature means an operating
temperature exceeding 60 °C (140 °F) or below 0 °C (32 °F). You must use
protective clothing, such as gloves, when handling equipment at these temperatures.
Display a warning notice concerning low or high temperature operation whenever
temperature control equipment is in use. You should note that the hazard from
extreme temperature can extend beyond the immediate area of the test.
Crush Hazard - Take care when installing or removing a specimen, assembly,
structure, or load string component.
Installation or removal of a specimen, assembly, structure, or load string component
involves working inside the hazard area between the grips or fixtures. When
working in this area, ensure that other personnel cannot operate any of the system
controls. Keep clear of the jaws of a grip or fixture at all times. Keep clear of the
hazard area between the grips or fixtures during actuator or crosshead movement.
Ensure that all actuator or crosshead movements necessary for installation or
removal are slow and, where possible, at a low force setting.
Hazard - Do not place a testing system off-line from computer control without
first ensuring that no actuator or crosshead movement will occur upon
transfer to manual control.
The actuator or crosshead will immediately respond to manual control settings
when the system is placed off-line from computer control. Before transferring to
manual control, make sure that the control settings are such that unexpected
actuator or crosshead movement cannot occur.
Robotic Motion Hazard - Keep clear of the operating envelope of a robotic
device unless the device is de-activated.
The robot in an automated testing system presents a hazard because its movements
are hard to predict. The robot can go instantly from a waiting state to high speed
operation in several axes of motion. During system operation, keep away from the
operating envelope of the robot. De-activate the robot before entering the envelope
for any purpose, such as reloading the specimen magazine.
