® WORKING NEAR MOBILE HEAVY ®For personnel on-foot/on-the-around near operating heavy equipment,follow safe work practices: EQUIPMENT,ON-SITE VEHICLES E • High visibility vests for all personnel in construction vehicle work area,on-site roadways and travel lanes. Hazards: • Maintain unobstructed vision:wear shaded eyewear only in bright sun;don't wear hoods. Struck-by • Erect barriers and post signs to identify and isolate the equipment hazard zone,if possible. Caught between • Stay out of swing radius of equipment,both in front and operating end,as well as at the back of equipment. Run over,roll over • Stay out of the travel path of operating heavy equipment. Overhead hazards/obstructions E • When crossing vehicle pathway behind moving equipment,cross at a distance not less than 30 feet. Elevated loads • When approaching equipment,always be able to see operator so he/she can see you. • Make eye contact with operator and use hand signals or make radio contact prior to approaching equipment. • Operator shall provide"all off"hand signal when it is safe to approach within swing radius of equipment. OPERATION OF MOBILE HEAVY ❑Operators shall follow safe work practices for operation of heavy equipment: EQUIPMENT E • Only trained/qualified persons allowed to operate heavy equipment. Hazards: • Wear seat belts;roll-over protection system present/deployed;do not exceed maximum safe slope. Struck-by • No passengers on moving/operating equipment except where passenger seat/restraint is present. Run over,roll over . Equipment inspected daily upon mobilization;maintained in good repair,backup alarms,windows clear. Caught between(pinch points) • Leaks or defective safety equipment should be repaired before use;fire extinguisher present. Fluid leaks/fuel-/fire-hazards . Maintain eye contact with ground personnel and use hand signals to direct their approach near equipment. Overhead hazards/obstructions • High visibility vests for all personnel in construction vehicle work area,on-site roadways and travel lanes. Potential for body . Cease operation if personnel enter swing radius,travel path or hazard zone of moving parts,elevated loads. entrapment/crushing • Use safe practices for fuel handling/storage/transport;spill equipment available for fuel/fluid leaks. Rotating equipment,moving • Equipment locked,secured,brakes set,buckets/forks lowered,extendable parts retracted,when not in use. parts. • Shut down/lock out equipment to prevent crush situation beneath or between moving parts of equipment. • Ensure personal/support vehicles are parked/located to not obstruct equipment travel lanes/operating zones. • Mark temporary roadways clearly,provide berms/stops where needed. HSE Program Documents: HSE SOP-644:Working Around Heavy Equipment TRENCHING/EXCAVATION ❑Safe work practices when personnel will enter trenches/excavations: Hazards: . Activities under supervision/oversight of Competent Person,conduct daily inspection of excavation. Cave-in,entrapment . Excavated materials placed at least 2'from trench sidewall. Hazardous atmosphere . Prevent water accumulation in trench. Water accumulation • Sloping&shoring for trenches/excavations>20'deep must be approved by a Professional Engineer. Falls into excavations . Sloping/shoring/trench box for excavations>5'when persons enter trench/excavation. Utility-related hazards Undermining structures& • Sloping/shoring/trench box for shallow(<5')trench/excavation with cave-in hazard. foundations • Workers in trenches shall be within 25 feet of ladder or sloped entryway. • Excavations shall be protected by perimeter fencing(not barricade tape),if potential for personnel to fall into. • If potential for atmospheric hazard,see D.12."Confined/Enclosed Spaces" HSE Program Documents:HSE SOP-432:Excavation and Trenching Activities FORKLIFT ❑In addition to general safety practices for heavy equipment(above),as applicable: Hazards: • Qualified operator,per established forklift training(certificate is required);Geosyntec operator must be Struck-by approved by Director of Health and Safety. Run over/roll over/tip over . Equipment inspected daily and documented on Forklift Preoperational Inspection Checklist. Overhead utilities/obstructions • Do not exceed lifting load limits. Caught between(pinch points) • Forklift shall not be moved/driven with empty forks in raised position. Unstable/falling loads . When not in use,forks lowered,brake set,controls in neutral,key removed. Elevated forks -Fluid leaks HSE Program Documents:HSE SOP-436:Safe Operation of Forklifts and Mobile Equipment AERIAL BOOM/SCISSOR LIFT ❑Follow safe work practices: Hazards: • Operators shall be appropriately trained and certified. Falls from basket • Equipment is inspected after mobilization and is in good condition. Overhead utilities/obstructions ' • Harness&lanyard worn when operating a boom lift(optional for scissor lift). Struck-by,run over,tip over . Overhead hazards and surface obstructions shall be reviewed with operators/riders prior to use. Caught between(pinch points) Tip over Fluid leaks. HSE Program Documents: HSE SOP-650:Manlifts and Aerial Lift Platforms(safe operation of mobile equipment) CRANES ❑In addition to general safety practices for Operation of Heavy Equipment(above),as applicable: Hazards: • Only qualified persons operate cranes(certificate required). — electrocution by overhead utility • Critical Lift Plan&Checklist prepared/executed(See Procedure)prior to mobilization. — injury in swing radius • Equipment shall be inspected prior to mobilization and daily by crane operator. — injury from falling load . Crane operator will remain at the controls at all times during operation. — crane tipping over due to . Crane operation must be performed under the direction of an appointed signal person at all times using hand overbalancing,high winds, unstable ground,unsafe slope, signals and/or voice/radio communication. bad placement of outriggers • Crane shall be level and stable(solid ground or crane mats/timbers,outriggers if present,cribbing);over- reaching or exceeding load limits is prohibited. aGeosyntec° Project/Task Name:Well Install,Development,and Destruction THA ver.
