Safety Today: ES&H Service Requests and Safety Issue Reporting
STAR Program Receives Boost

Good CalibrationsLike most men with work trucks, SLAC Geodetic Engineer Georg Gassner uses his for hauling equipment. However, when he transports the most accurate field instrument in the world, he takes extraordinary precaution. He places the $140,000 laser tracker in a strapped down case, padded with a 5-inch layer of foam. Portable laser trackers provide incredibly accurate measurements—up to 30 micrometers for distance and 1 arc second for angles. Laser trackers' measurements make them ideal tools for aligning large mechanisms in endeavors demanding extreme precision. At SLAC, laser trackers will allow the heavyweight machinery of the Linac Coherent Light Source (LCLS) to be positioned down to 80 micrometers over short distances and to 300 micrometers over the machine's 140-meter length. "It would be virtually impossible to meet the geometrical requirements for the LCLS without the help of laser trackers," Gassner said. Read more... |

ES&H Service Requests and the Reporting of Safety Issues
The Environment, Safety and Health (ES&H) division recently reviewed the way it handles service requests and safety issue reporting. The lab currently has three telephone numbers relating to safety: emergencies (911), safety service requests (x4554), and hotline issues (x4641). These numbers will remain in service, but their functions have shifted slightly. All environmental, safety and health emergencies should be reported by calling 911. 911 is our lifeline to internal and external emergency assistance and will bring in medical, fire or police assistance, as needed. Please note that calling 9-911 and calling 911 will both connect you to emergency response. By dialing the second number (x4554), a caller reaches the Safety Service desk, where he or she can report any environmental, safety or health concerns not considered to be an emergency or life threatening. This phone number remains in service, ringing in the safety offices and, in the event no one is there, ringing at Security. The third number (x4641) has in the past been known as the "safety hotline." It was originally established to provide SLAC employees with a way to report an anonymous safety issue. As with x4554, this number remains in service, however it is not for emergency use and thus will no longer be considered a "hotline." The 4641 extension is now to be used only if there is an issue you wish to report anonymously, and will from now on be referred to as the "anonymous report line." Remember: Dial x4554 for safety related concerns of a non-emergency nature, x4641 for anonymous reports and 911 for all emergencies. |
