Log Unloading Methods Top

Hazard/Solutions:

Logs that are released improperly due to poor work practices may crush workers.

  • Release binders only from the side on which the unloader operates, except when released by remote control devices or when the person making the release is protected by racks or stanchions or the equivalent. 1910.265(d)(1)(i)(c)

  • Loads on which a binder is fouled by the unloading machine must have an extra binder or metal band of equal strength placed around the load, or the load must be secured so the fouled binder can be safely removed. 1910.265(d)(1)(i)(d)
  • The tripping mechanism that releases the stake or chocks must be on the opposite side of the load being tripped. 1910.265(d)(1)(i)(a)

  • Do not release binders on logs prior to securing with unloading lines or other unloading devices. 1910.265(d)(1)(i)(b)

The following sequence of pictures depicts a safe unbinding and unloading procedure:

The carrier truck approaches from the far side and places carrier mechanism over load and secures it for the approaching truck drivers. Note: The load binders are still secured in place.

Log Unloading Equipment Top

Hazard/Solutions:

Loads could fall and strike or crush workers due to equipment failure.

  • Machines used for hoisting, unloading, or lowering logs must be equipped with brakes capable of controlling or holding the maximum load in midair. 1910.265(d)(1)(ii)(a)

  • The lifting cylinders of all hydraulically operated log handling machines must be equipped with a device that prevents uncontrolled lowering of the load or forks in case of a failure in the hydraulic system. 1910.265(d)(1)(ii)(b)

  • A limit switch must be installed on powered log handling machines to prevent the lift arms from traveling too far in the event the control switch is not released in time. 1910.265(d)(1)(ii)(c)

  • When forklift-type machines are used to load trailers, a means of securing the loading attachment to the fork must be installed and used. 1910.265(d)(1)(ii)(d)

  • A-frames and similar log unloading devices must provide safe clearance for swinging loads, crotch lines and spreader bar devices. 1910.265(d)(1)(ii)(e)

  • Log handling machines used to stack logs or lift loads above operator's head must be equipped with adequate overhead protection. 1910.265(d)(1)(ii)(f)

  • All mobile log handling machines must be equipped with headlights and backup lights. 1910.265(d)(1)(ii)(g)


  • Unloading devices must be equipped with a horn or other noise-making device. 1910.265(d)(1)(ii)(h)

  • When the operator's vision is impaired or when operating in the vicinity of other employees, coordinate the movement of unloading equipment with audible or hand signals. 1910.265(d)(1)(ii)(i)

Unloading and Storage Areas - General Top

Hazard/Solutions:

Workers may be struck by loads or equipment in unsafe log dumps, booms, ponds, or storage areas.

  • Log dumps, booms, ponds, or storage areas used at night must be illuminated in accordance with the requirements of American National Standard A11.1-1965 (R-1970) Standard Practice for Industrial Lighting, which is incorporated by reference as specified in Sec. 1910.6. 1910.265(d)(2)(i)(a)

  • Log unloading areas must be arranged and maintained to provide a safe working area. 1910.265(d)(2)(i)(b)

  • Where skids are used, maintain a space adequate to clear a man's body between the top of the skids and the ground. 1910.265(d)(2)(i)(c)

  • Post signs prohibiting unauthorized foot or vehicle traffic in log unloading and storage areas. 1910.265(d)(2)(i)(d)

Dry Deck Storage Top

Hazard/Solutions:

Logs that are stored in an unsafe manner could move or fall, then strike or crush workers.

  • Dry deck storage areas must be kept orderly and maintained in a condition that is conducive to safe operation of mobile equipment. 1910.265(d)(2)(v)(a)

  • Logs must be stored in a safe and orderly manner, and roadways and traffic lanes must be maintained at a width adequate for safe travel of log handling equipment. 1910.265(d)(2)(v)(b)

  • Logs must be arranged to minimize the chance of accidentally rolling from the deck. 1910.265(d)(2)(v)(c)

Hazard/Solutions:

Workers could be struck by logs or crushed due to unsafe work practices.

  • Safe access to the head rig must be provided. 1910.265(d)(3)(i)

  • Log decks must be provided with adequate stops, chains, or other safeguards to prevent logs from rolling down the deck onto the carriage or its runway. 1910.265(d)(3)(ii)

  • Erect a barricade to stop any log between the sawyer's stand and the log deck. 1910.265(d)(3)(iii)
