Improper access to vessels, spaces, dry docks, and
marine railways increases the risk of fall, struck-by, and crushing
hazards.
Inadequate guarding of drydock and marine
railway equipment exposes workers to crushing and caught-between hazards
such as
pinch-point. Deck edge and work surface guards are critical in
preventing elevated falls.
Note: Confined space entry is one of the leading hazards associated with barge cleaning. Review the Ship Repair: Confined or Enclosed Spaces and Other Dangerous Atmospheres chapter for information on how to protect workers from this hazard.
