Walking/wading into water,on shoreline, ❑For work over very cold water,have immersion survival suit available.
<br /> riverbank,dock,bulkhead,abutment,coal ash: ❑For tidal,flash flood,dam release hazards,plan/locate work accordingly.
<br /> ❑Wading/walking into/near water,wetland ❑For towing a boat trailer,see D.2."Special Driving/Traffic/Transportation Hazards."
<br /> ❑Hazardous tidal zone or surf ; Wading in water or walking along shore/bank or on dock/pier/abutment:
<br /> ❑Water release,flash flood ! ❑For ice/slip hazards,wear ice creepers,sand work area,use tether,other appropriate measures.
<br /> ❑Coal ash pond,quicksand,soft ground ! ❑For work on ice over water,verify safe thickness,have ring buoy&rope available
<br /> ❑Open culvert,arroyo,drainage/irrigation ditch ; ❑For unsure/slippery footing in water,use wading staff,high-traction soles on waders.
<br /> ❑Ice hazard on or near waterbody ! ❑Have lifesaving skiff/boat available in circumstances where other rescue means are inadequate.
<br /> Diving ❑Monitor hazardous tides,weather for flash floods,know water release schedule.
<br /> ❑Scientific SCUBA diving ! For soft ground,ash ponds,quicksand:
<br /> Hazards(as applicable): ❑Wear personal flotation device(PFD),as appropriate for the work task and work environment.
<br /> Drowning,cold immersion ❑Bring emergency rescue equipment(ring buoy and rope,reaching device)
<br /> Boating collision,navigation,fog,darkness ❑If walking on ash/quicksand,provide stable walking/working surface(4'x8'plywood,or similar)
<br /> Fire/fuel hazards ; For diving:
<br /> Entrapment(mud/silt/coal ash/quicksand) ❑Develop a diving safety plan approved by Geosyntec's diving coordinator
<br /> Slip/fall hazards—ice,mud,silt,wet surfaces For chemical contaminant and/or biological/infectious hazard:
<br /> Weather,heat/cold stress ❑See Section(s)DA.b.,"Biological Hazards,D.13.,"Infectious/Allergenic Biohazards,"
<br /> Equipment failure,hypoxia D.14.,"Commercial Chemical Products,"and/or D.15.,"Site Contaminants,Chemical Wastes"

<br /> HSE SOP-434a:Overhead and Underground Utility Hazards(US-only)
<br /> LADDER/STAIRS ❑Follow safe work practices:
<br /> ❑ Extension/straight ladders . Use ladders according to safe practices and manufacturer's instructions.
<br /> ❑ Stepladders • Maintain 3 points of contact at all times on ladder;keep center of gravity within side rails.
<br /> ❑ Fixed/installed ladders • Do not use metal(conductive)ladder near electrical hazard.
<br /> ❑ Portable/mobile stairs • Extension/straight ladders shall be properly footed,secured,angled,extend above upper work surface.
<br /> El Job-made or scaffold stairs • Stepladders are set on level ground or properly shimmed,spreaders locked;do not climb/stand on top
<br /> step,top cap,or rear non-climbing side;use step ladder of sufficient reach height for work.
<br /> Hazards: . Equip stairs with stair handrails where more than 4 steps,and for stairway height of 4'or more.
<br /> See general fall hazards,above. Ensure portable stairs are stable,plumb,and of sufficient reach height for task.

<br /> HSE SOP-638:Ladders and Stairways
<br /> SCAFFOLD ❑Follow safe work practices:
<br /> ❑Supported scaffold • Identify/coordinate operations with the scaffold"Competent Person."
<br /> ❑Suspended scaffold • Supported scaffold level,stable,proper attachments,tiebacks,planking,
<br /> ❑Free-standing/mobile scaffold • Suspended scaffolds anchored properly.
<br /> • Guardrails or personal fall apparatus required above 10 feet.
<br /> Hazards: • Proper means of accessing scaffold(proper ladders,stair tower);don't climb scaffold frames.
<br /> See general fall hazards,above • Total height of free-standing scaffold shall not exceed four times the minimum base dimension.
<br /> Equipment collapse • Don't exceed load limits,distribute loads evenly,stage materials in quantities sufficient for immediate use.
