Safety Information

Safety

Stay clear of moving

equipment/avoid crush

points

Know the causes of

unexpected crosshead

motions

Do not use RF

transmitters

Stay clear of mechanical linkages, connecting cables, and hoses that move because you can get pinched, crushed, tangled, or dragged along with the equipment. High forces generated by the system can pinch, cut, or crush anything in the path of the equipment and cause serious injury. Stay clear of any potential crush points. Most test systems can produce sudden, high-force motion. Never assume that your reactions are fast enough to allow you to escape injury when a system fails.

The high force and velocity capabilities of MTS systems can be destructive and dangerous (especially if crosshead motion is unexpected). The most likely causes of unexpected crosshead response are operator error and equipment failure due to damage or abuse (such as broken, cut, or crushed cables and hoses; shorted wires; overstressed feedback devices; and damaged components within the control loop). Eliminate any condition that could cause unexpected crosshead motion.

Keep radio frequency (RF) transmitters away from the workstation computers, remote terminals, and electronics consoles. Intense RF fields can cause erratic operation of the more sensitive circuits in the system.

Hazard Placard Placement

Hazard placards contain specific safety information and are affixed directly to the system so they are plainly visible.

Each placard describes a system-related hazard. When possible, international symbols (icons) are used to graphically indicate the type of hazard and the placard label indicates its severity. In some instances, the placard may contain text that describes the hazard, the potential result if the hazard is ignored, and general instructions about how to avoid the hazard.

The following labels are typically located on the chamber.

Series FEC Environmental Chamber Product Manual Routine Maintenance

• Do not open the chamber immediately after a test to prevent damage or

personal injury caused by high or low temperature.

• To extend the service life of an environmental chamber, eliminate water

vapor in the cabinet or other residue left in the chamber after test.

• Do not use corrosive organic solvents when cleaning chamber.

• During test or after test, do not use any kind of shelter to cover the chamber

so as to avoid the case that the heat or water vapor can not be diffused and damage the chamber.
