Operations and Maintenance Manual Universal Vacuum System
Version 1.2—March 2004 Page 7
• Recommendation Only: Avoid long-term exposure to low frequency electromagnetic
fields. The data concerning low-frequency electromagnetic health effects is
inconclusive, but a 1995 IEEE engineering publication recommends “prudent
avoidance” of prolonged and continuous exposure. Maintenance personnel are advised
to avoid standing at open power panel doors for extended periods with the power on.
Pregnant women, in particular, should heed this advice. Closing cabinet effectively
shields all personnel from any perceived hazardous fields. Studies are being conducted
by the U. S. Department of Energy to determine what risks, if any, are posed by low
frequency electromagnetic field exposure.
• Always consult with your supervisor if your task or procedure is unclear or if you
believe that your assignment could result in unsafe conditions or equipment damage.
REMEMBER:
The safe way is the best way.
HAZARDS INHERENT IN DEVICE
The machine is moderately heavy. It should remain upright and not be dropped. During
transport it should be secured so as not to impact other objects.
The machine is tall with a narrow footprint. It should not be set down in such a way as to
break through the floor surface or cause any floor sagging that could throw it out of level. It
should be placed and secured so that there is no foreseeable danger of tipping over in an
earthquake, flood, fire or other accident. See Seismic Protection section.
INHERENT HAZARDS PREVENTABLE BY USER PRECAUTIONS
• Danger of being struck, shocked or burned by internal parts if the interlock door is
bypassed or becomes inoperative.
• Danger of discharge of pressurized air.
• Danger of moving parts damaging the machine or rupturing the cabinet.
• The risk of this machine causing a fire through electrical or mechanical causes.
CONCLUSION
Built-in safety devices and warnings are sufficient to protect against all these dangers when
the machine is installed and used responsibly in accordance with established safety
procedures.
