<strong>DOE</strong>-<strong>STD</strong>-<strong>1090</strong>-<strong>96</strong> (Rev-l)7.5 OPERATIONa. The following shall apply to all personnelinvolved in overhead <strong>and</strong> gantry crane operation.b. At the initial stage ofthe planning process,an appointed person shall classify each lift intoone ofthe <strong>DOE</strong>-specified lift categories (ordinary,critical, orpreengineered production).7.5.1Conduct of Operator.a. Do not engage in any practice that willdivert your attention while operating the crane.b. Do not operate cranes without complyingwith the requirements of Chapter 6. Yourimmediate supervisor shall participate in thisdetermination.c. Operators shall be held directly responsiblefor the safe operation oftheir equipment.Whenever there is any question as to the safety ofthe activity, an operatorhas the authority to stop<strong>and</strong> refuse to h<strong>and</strong>le loads until the matter hasbeen resolved by supervisory personnel.d. Sound a warning signal (iffurnished) duringtravel, particularly when approaching personnel.e. Ifyou fmd the crane's main or emergencyswitch open when starting on duty, do not close ituntil it has been determined that no one is on orclose to the crane. Ifthere is a warning sign on theswitch, do not remove it unless you placed it there.Do not close the switch until the warning sign hasbeen removed by the person who placed it there.f. Before closing the main switch, ensure thatall controllers are in the OFF position.g. Ifa power failure occurs during operation,immediately switch all controllers to the OFFposition.h. , Become familiar with your equipment <strong>and</strong>its proper care. Ifadjustments or repairs arenecessary, or any defects are mown, report thempromptly to the responsible supervisor. Also,notify the next operator ofthe defects at shiftchange.i. Contacts with runway stops or other cranesshall be made with extreme caution. Ifyou areordered to engage with or push other cranes, dothis with particular care for the safety ofpersonson or below the cranes, <strong>and</strong> only after makingcertain that any persons on the other cranes areaware ofwhat action is to be taken.j. Secure outdoor cranes before leaving them.Ie. When the wind-indicating alarm is given,anchor the bridge on outside cranes.1. Lock <strong>and</strong> tag the main positive electricalcontrol switch in the OPEN position before anycrane maintenance is performed.m. Operate all controls before beginning a newshift. Ifany controls do not operate properly,adjust or repair them before operations begin.n. Do not hoist two or more separately riggedloads in one lift, even though the combined loadiswithin the crane's rated capacity.o. Ensure that a 10BC or larger fIreextinguisher is installed in the cab ofcab-operatedcranes. The extinguisher shall be maintained in aserviceable condition.p. Do not lift, lower, or travel the crane whileanyone is on the load or hook.7.5.2 Hoist-LimitSwitch/Devicea. At the beginning ofeach work shift, or thefIrst time the crane is used during a shift, test theupper-limit switch/device ofeach hoist under noload. Exercise extreme care to avoidtwo-blocking; "inch" the block into the limitswitch or run it in at slow speed. Iftheswitch/device does not operate properly,immediately notify the supervisor.b. Ifa lift is in progress during a shift change,this testing requirement is considered to have beensatisfied for the completion ofthat lift. However,test the limit switch again before the next lift.c. Do not use the fmal hoist-limit switch!device that controls the upper limit of travel oftheload block as an operating control.7.5.3 <strong>St<strong>and</strong>ard</strong> H<strong>and</strong> SignalsThe st<strong>and</strong>ard h<strong>and</strong> signals for <strong>DOE</strong> use shall be asspecified in the latest edition ofthe ASME B30st<strong>and</strong>ards for the particular type of crane or hoistbeing used (see Figure 7-4).7·13Chapter 7Overhead <strong>and</strong> Gantry Cranes
