Job Safety Analysis: Debris Removal from Streams

Print
Step Potential Hazard Control
Assess stream and access area Fast water, unstable banks, deep pools, slippery rocks, wildlife Conduct site walk; choose safest access point; probe soft or underwater areas; avoid working on undercut banks
Inspect tools and equipment Damaged chainsaws, dull blades, broken hooks, faulty ropes or rigging Perform pre operation inspection; verify chainsaws, hand saws, hooks, and rope gear are in good condition
Don required PPE Waterborne hazards, sharp debris, insects, cold water exposure Wear waders or waterproof boots, gloves, safety glasses, and hard hat; apply insect repellent
Establish safe work zone Crew entering unstable zones, falling branches, equipment contact Mark safe areas; keep workers out of downstream hazard path; maintain communication among crew
Evaluate debris type (wood, trash, sediment, vegetation) Unknown hazards, hidden sharp objects, contamination Identify debris visually; avoid reaching into water blindly; use tools to probe material
Remove debris manually Slips, cuts, heavy lifting, rolling logs Use hooks, rakes, or rope assists; maintain firm footing; avoid twisting while lifting; use team lifts for heavy items
Cut large woody debris Chainsaw kickback, slipping into water, falling limbs Only cut from stable ground; never cut while standing in water; maintain two handed grip; keep bystanders clear of drop zones
Use mechanical equipment (excavator, skid steer) Equipment rollovers, struck by bucket, crushing hazards Establish exclusion zone; keep workers away from swing radius; operate on stable ground only
Manage water flow Sudden surge if blockage releases, worker swept downstream Remove debris in small portions; keep lookout downstream; maintain escape route if water rises
Handle trash or hazardous materials Contact with chemicals, sharps, contaminated water Use puncture resistant gloves; avoid opening containers; place hazardous items in separate containers; follow municipal disposal protocols
Stabilize streambank if disturbed Unstable slopes, erosion Place riprap or erosion control materials as needed; avoid standing on loose soil; work from stable surface
Inspect for upstream or downstream impacts Slipping, wading hazards Move carefully; probe depth before stepping; ensure water flow is unimpeded
Clean up and collect removed debris Trips, heavy lifting, contamination Place debris away from water; bag lightweight waste; load larger debris with mechanical equipment
Final inspection Missed debris, unstable banks Walk area safely; verify stream flow is restored; remove any remaining hazards
Remove traffic control (if roadway adjacent) Worker exposure to traffic Remove cones and signs in reverse order; maintain lookout; keep PPE on until clear

Suggested Personal Protective Equipment

  • Hard hat

  • Safety glasses or face shield

  • High visibility vest or jacket (if near roadway)

  • Waterproof boots or chest waders

  • Cut resistant gloves

  • Steel toe boots (if using heavy tools or equipment)

  • Long pants and long sleeves

  • Hearing protection when using chainsaws or power tools

  • Respirator if exposed to mold, decaying organics, or sediment dust

Always have a complete, well-stocked first aid kit available.
