4 Lckut/Tagut Prgram 3.0 IDENTIFICATION OF ENERGY SOURCES UCSD Maintenance and research departments, which have hazardus energy surces, must identify all machinery and equipment that is subject t LOTO. Panel schedules will be maintained and updated by the department r cntractr perfrming any mdificatins r wrk in the area. 4.0 ENERGY CONTROL PROCEDURES Each written prcedure fr the cntrl f hazardus energy will cntain the fllwing steps. 4.1 Lckut/Tagut f Equipment Prcedures When servicing r maintenance f machinery r equipment is required, the fllwing steps shall be taken. Ntify affected emplyees. The authrized emplyee shall identify the type(s) and magnitude(s) f energy that the machine r equipment uses. The authrized emplyee shall understand the hazards f the energy, and shall knw the methds t cntrl the energy. If the machine r equipment is perating, shut it dwn by the nrmal stpping prcedure (depress the stp buttn, pen switch, clse valve, etc.). De-activate the energy islating devices(s) s that the machine r equipment is islated frm the energy surce(s). Lck ut the energy islating device(s) with assigned individual lck(s) and tags. Stred r residual energy (such as that in capacitrs, springs, elevated machine members, rtating flywheels, hydraulic systems, air, gas, steam, water pressure, etc.) must be discharged, dissipated r restrained by methds such as grunding, repsitining, blcking, blanking r bleeding dwn t remve r islate stred energy ptentials. Ensure that the equipment is discnnected frm the energy surce(s) by first checking that n persnnel are expsed, then verify the islatin f the equipment by perating the start n/ff buttn r ther nrmal perating cntrl(s) r by testing t make certain the equipment will nt energize r perate. Cautin: Return perating cntrl(s) t neutral r "ff" psitin after verifying the islatin f the equipment. The machine r equipment is nw lcked ut. Remve machinery guards r access panels necessary t perfrm wrk. 4.2 Restring Equipment T Service When servicing r maintenance is cmpleted and the machine r equipment is ready t return t nrmal perating cnditin, the fllwing steps shall be taken.

6 Lckut/Tagut Prgram The assessment will be designed t identify and crrect deficiencies. During the assessment, prcedures will be reviewed by authrized emplyees wh will assist in the identificatin f deficiencies and the develpment f slutins. Dcumentatin f the assessment will include the machine r equipment evaluated the date f the assessment, the peple invlved and any crrective actin taken. These recrds will be kept fr at least five (5) years in the department ffice. 7.0 TRAINING The department, supprted by EH&S, will be respnsible fr training t ensure the purpse and functin f the LOTO prgram is understd by all authrized and affected emplyees. Authrized emplyees will receive training in the recgnitin f applicable hazardus energy surces, the type and magnitude f the energy available in the wrkplace, and the methds and means necessary fr energy islatin and cntrl. The training will be dcumented n Frm #2 in Appendix III. Affected emplyees will be instructed in the purpse and use f the energy cntrl prcedure. The training/instructin will be dcumented n Frm #3 in Appendix III. Other emplyees whse wrk peratins are r may be in an area where energy cntrl prcedures may be utilized, will be instructed abut the prcedure and abut the prhibitin relating t attempts t restart r re-energize machines r equipment which are lcked ut. The instructin will be dcumented n Frm #4 in Appendix III. Retraining will be cnducted when emplyees n lnger demnstrate an understanding r prficiency with the LOTO prgram, when jb assignments change, when equipment r prcesses are mdified r when new equipment is installed. In the event that Tagut devices must be utilized the training will include the fllwing: Tags are warning devices they d nt prvide any type f physical restraint. Tags cannt be remved ther than by the authrized persn wh applied the tag and must fllw the same steps when remving a lckut device. Tags must be legible and understandable. Tags must be made ut f material that is capable f withstanding the envirnment in which they are used. Tags must be securely attached. 8.0 CONTRACTORS Cntractrs must have a written LOTO Prgram in place that is as stringent as the UCSD prgram.
