ContraCostaWaterDistrict’s (District) goalistoprovide everyone withthebenefitsofasafeand healthyworkenvironment. TheDistrictiscommittedtomaintainingaworkplacefreefromwork- relatedinjuriesandillnesses,andtocomplyingwithapplicablelawsandregulations governing workplacesafety.
To help achieve these goals, the District has developed a Contractor/Consultant Safe PracticesHandbook. Thesesafepracticesoutlinedinthishandbookareintendedtofostera safeandhealthfulworkenvironment.
It is theresponsibilityof everyoneto work togetherto identifyand eliminateconditionsand practicesthatcreateanunsafeorunhealthyworkenvironment.

4.Ensurethereisadequatelightingtoperformthejobsafely.
5.Donotenterconfinedspaces(vaults,tanks,buriedreservoirs,andpipes)unlessyouare trained,havemonitoredtheatmosphere, andhaveeliminatedorcontrolledallserious hazards. NotifytheDistrict 24hoursbeforeaconfinedspaceentry. SeeConfinedSpaces sectionforotherrequirements.
6.Keepyourworkareacleanandorderlyatalltimestopreventslips,tripsorfalls. Place barriersorwarningsignsatlocationswithwetfloors.
7.Attendpre-jobsafetybriefings. TheDistricttreatment plantsandLosVaqueros Watershed haveadditional visitorsafetyrules.

FollowtheDistrict’sEnergyControlProcedures,whichincludetheselockandtagprocedures duringallconfinedspaceentriesandallconstructionandmaintenance activitiesonmachineryor equipment whereahazardous releaseofenergyispossibleincludingelectrical,mechanical, chemical,hydraulic,pneumaticandpotential.
1.Notifyallaffectedpersonnel(includingoperatorsofmachinery/equipment/facility)duringa hazardanalysistailgatemeetingbeforetheactivity.
2.Followthe District’sEnergyControlProcedures(ECP) for the specificDistrictequipment/ systems. CoordinatewithDistrictstafftoidentifyallhazardousenergysources,theirenergy isolationdevices(e.g.,circuitbreakers,valves,etc.),controlcircuit-type devices(e.g.,push buttons, selector switches, etc.), block-out points, drain/bleed points and energy indicator devices(e.g.,gauges,panellights).
3.Shutdown. Alloperating controlsshallbeturnedofforreturnedtotheneutralposition(depress stopbutton,openswitch,closevalve,etc.).Deactivate theenergyisolationdevicesothatthe machine/equipmentisisolatedfromtheenergysource.Disablemotor-operatedvalves.
4.Lockout.A lockingdeviceisplacedoneachenergy-isolatingdeviceor projectlockboxto isolate eachenergysource.Eachemployeeinvolvedshallplacetheir own uniquelykeyedlock andtag ateachisolationpoint,oratthelockbox.
