Log strikes forwarder cab

Safety Alert Type: 
Yarding and Loading
Location: 
New Zealand
Date of Incident / Close Call: 
2018-01-24
Company Name: 
Innovative Forestry Specialists (NZ)
Details of Incident / Close Call: 

While loading logs with a forwarder grapple in steep terrain, a log on top of the bunk was crossed up.

The machine jerked while clearing the haul track, causing the log to slide over the headboard, hit the windshield and slide right through the cab and out the back window, narrowly missing the operator.

Learnings and Suggestions: 
  • Main cause: a crossed up log on top of the load that slipped over the top of the cab guard
  • Operator must take care loading logs, ensuring that all logs are located beneath cab guard
  • Review harvesting system – i.e. shovel or grapple stems to a safer location to process and then forward logs to skid
  • Cab window failed safety specification – it did not withstand impact of log. This needs reviewing / modification.

Worker's finger in the bight of wire rope caught on stump

Safety Alert Type: 
Yarding and Loading
Location: 
New Zealand
Date of Incident / Close Call: 
2018-08-29
Company Name: 
Forest Management New Zealand Ltd.
Details of Incident / Close Call: 

The incident occurred during a routine line shift, when a worker attempted to release the tail rope which had snagged on a stump.

After stopping the rope and getting slack he went in to throw the rope over the stump. He saw that there was slack in the rope from the stump to the hauler but couldn’t see that down the hill the rope still had weight on it over the gully.

He gave the rope a yank holding the tail rope each side of the stump, the movement caused the rope to move quickly dragging his hand around the stump crushing his middle and ring fingers.

This incident resulted in a lost time injury with the worker losing part of his middle finger, and highlights a work activity that takes place on a regular basis and may be getting overlooked for risk assessment.

Learnings and Suggestions: 
  • Don't rush to un-snag a wire rope without first stopping to properly assess the situation. Complete a thorough risk assessment.
  • Never assume - look for any part of the wire rope that may still be suspended or under tension, slacken ropes further if necessary.
  • Ask for assistance from a co-worker (another pair of eyes and/or hands) if you need to.

Forklift clips load; stacked lumber spills onto work station

Safety Alert Type: 
Sawmills and Reman
Location: 
Acorn Sawmill (Delta, BC)
Date of Incident / Close Call: 
2019-01-16
Company Name: 
INTERFOR
Details of Incident / Close Call: 

A stack of kiln-sticked lumber spilled onto the labelling area when the forklift operator attempted to remove the stack of lumber that was stored in front of it.

The forks clipped the load, which was the top load of a stack of two, causing it to topple over as the operator attempted to remove the two loads in front.

No other workers were in the vicinity at the time of the incident.

Learnings and Suggestions: 
  • Evaluate the condition of the loads and surrounding area prior to handling any loads with mobile equipment
  • Always be aware of the positioning of your forks and the distance between each stack when handling loads
  • Investigate alternative storage stacking arrangements to mitigate interface between loads and workers
  • Slow and steady movements reduce the chance of incidents when operating mobile equipment.

Log in bundle slides, breaking window on boom boat

Safety Alert Type: 
Booming and Towing
Location: 
Castlegar, BC
Date of Incident / Close Call: 
2019-01-15
Company Name: 
INTERFOR
Details of Incident / Close Call: 

A boom boat operator pushed a log bundle onto the cradle. The operator raised the cradle out of the water and stopped just as the bundle cleared the water to check for any logs protruding upstream, as is the normal procedure.

One log was crooked in the bundle and protruded 'upstream' 4-5 feet and needed to be pushed in. As the operator went in to push the log, the log slid on top of the gavel (front tie-off point). The operator put the boat into reverse but the momentum and the time it took for the boat to reverse was too late to prevent the log from striking the protection cage of the windshield. As a result, the log bent the safety cage causing the windshield to fracture.

Learnings and Suggestions: 
  • Keep logs as low as possible to prevent the logs from coming over the top of the boat hull when pushing in logs back into position
  • Ensure the teeth on the front of the boom boat are in good condition so they will bite into the log when pushing.

Trailer loader malfunction damages log truck

Safety Alert Type: 
Heavy Equipment
Location: 
Port Angeles, WA
Date of Incident / Close Call: 
2019-01-15
Company Name: 
INTERFOR
Details of Incident / Close Call: 

A log truck driver was loading his trailer at the trailer loader. The current setup requires drivers to use foot pedals and a pike pole to maneuver the trailer into position.

The trailer got hung up on the stakes causing the hitch to swing down and contact the cab. The driver was unable to stop this action as he could not remove his foot from the down switch before the damage occurred, in addition to the actuator intermittently sticking.

Upon further investigation, there was mud buildup near the foot pedal actuator that was causing intermittent sticking. The driver was wearing appropriate hiking boots.

The resulting damage was a broken windshield, broken fiberglass on cab and a bent deflector.

Learnings and Suggestions: 
  • All lifting equipment should be appropriately inspected and maintained
  • A monthly cleaning preventative maintenance (PM) will be created to ensure housekeeping standards are kept.
  • The foot pedal toe cap will be raised by a ½ inch
  • Stay clear of the bite - never get under elevated loads.

The importance of correct body position while limbing trees

Safety Alert Type: 
Bucking and Limbing
Location: 
Coastal British Columbia
Date of Incident / Close Call: 
2019-01-14
Company Name: 
INTERFOR
Details of Incident / Close Call: 

A helicopter hill crew bucker sustained a laceration behind his left knee after the chain was thrown from the saw bar. The worker was standing on top of an adjacent log while limbing.

The worker was under bucking a loaded limb with the chainsaw positioned across his body. While bucking the limb the saw chain came off the bar and whipped around the back of the workers left knee, resulting in a small laceration.

Learnings and Suggestions: 
  • Avoid limbing across the body with a chainsaw
  • Ensure safety devices on the saw are working correctly including chain catcher
  • When bucking loaded limbs, put in a series of tension relief cuts
  • Follow procedures and information contained in the BC Faller Training Standard InfoFlips.

Board contacts grading machine photoeye

Safety Alert Type: 
Sawmills and Reman
Location: 
Castlegar, BC
Date of Incident / Close Call: 
2019-01-11
Company Name: 
INTERFOR
Details of Incident / Close Call: 

The Lineal High Grader (LHG) operator went to pull the LHG out in order to clean the scanner. At the same time, the Planerman was doing an adjustment to the Planer.

As the LHG was being backed out to be cleaned, the Planerman jogged a board forward, pushing it into the LHG. The board made contact with the infeed photo eye.

The LHG was shut down, stop button pushed, and permissive button pressed to prevent the rolls from moving. The PLC controls stopped the “planer feed auto” but did not stop the “jog” function. The PLC controls did not allow this fuction previously and had been changed at some point to allow this to happen.

This procedure did not require a lockout because employees were never entering the bite and only cleaning from outside of the area using an air wand. Potential for LHG damage or possibility of boards protruding from the feed line exist.

Learnings and Suggestions: 
  • The Safe Work Procedures for the LHG now requires a full lockout of the LHG when cleaning or inspecting. This means that a lockout is required any time the LHG main frame is moved to the “out” position or out of the feed line.
  • The LHG frame acts as a safety barrier and when in the “out” position, the potential for someone to enter the bite exists. Serious injury could occur.
  • PLC Controls cannot be used as a safe guard when removing guards or barriers, where potential for injury or damage exists.

Packaging worker's thumb gets stapled

Safety Alert Type: 
Sawmills and Reman
Location: 
Castlegar, BC
Date of Incident / Close Call: 
2019-01-09
Company Name: 
INTERFOR
Details of Incident / Close Call: 

At the mill's paper wrap station, there was a package of mixed length lumber to tag. The economy packages do not require to be paper wrapped, only tagged. The tags are required to be stapled to the package.

The operator stapled the top of the tag and the tag curled up from the bottom. The operator held the bottom of the tag. When he was attempting to staple the bottom left corner, he inadvertently put a staple into his left thumb.

The operator had the trigger depressed while he was applying staples. He was wearing Gander Brand Ninja X4 gloves.

Learnings and Suggestions: 
  • OMER Brand tools are equipped with a safety mechanism and can only fire when the safety and trigger are depressed at the same time.
  • Operator was holding trigger and using the safety to fire the tool.
  • Cap Staple Tools were used on all products except for cedar and for “tag only” packages.
  • Ensure proper hand placement while stapling and using the trigger to fire OMER tools.
  • Cap Staple Tools function the same as OMER Staple tools. Cap tools automatically place caps, and will now be used to staple tags on all packages.
  • Cap Staple Tools require less manual hand use for opposite hand and have a wide safety mechanism that helps to keep the tool farther away from the opposite hand.

Log loader mechanical failure on boom and stick hinge point

Safety Alert Type: 
Yarding and Loading
Location: 
Adams Lake Woodlands (Chase, BC)
Date of Incident / Close Call: 
2019-01-10
Company Name: 
INTERFOR
Details of Incident / Close Call: 

A log loader was swinging a grapple of long logs onto a truck trailer and a mechanical failure in the boom hinge occurred resulting in the load of logs dropping.

The steel pipe on the stick side of the boom/stick hinge-point broke away. After the break, the boom and stick assembly were supported by the cylinder and hoses. A post-incident inspection found that only half the pipe was welded --- there was not a continuous weld all the way around.

During regular greasing of the hinge point, this location is greased remotely near the grapple end as there is no practical method to regularly service or inspect this location.

The truck driver was in the clear and not at risk of being struck by a log.

Learnings and Suggestions: 
  • Always stay in the clear around active equipment and overhead hazards.
  • At regular intervals, a qualified person should thoroughly inspect and test machine components and welds that regularly receive heavy loads.
  • Operators using a 2015 Tigercat 875 log loader should inspect the hinge for weld defects.

Lockout violation due to unfamiliarity with disconnect locations

Safety Alert Type: 
Sawmills and Reman
Location: 
Acorn Sawmill (Delta, BC)
Date of Incident / Close Call: 
2019-01-10
Company Name: 
INTERFOR
Details of Incident / Close Call: 

A sawmill lockout violation occurred when an employee entered the barker infeed conveyor to conduct maintenance work.

Although the employee had sufficiently locked out the barker, locking out of the hydraulic log loaders located on another MCC was missed. The Lockout verifier was also unaware that the disconnect for the log loaders had to be locked out at a different location.

Both employees are relatively new to their positions, however they have been trained. Prior to the actual work commencing, the violation was discovered and the employee in the barker infeed was pulled from the work area.

Learnings and Suggestions: 
  • Take the required time to identify all pieces of equipment, energy sources and disconnect locations when locking out. Multiple locations and energy sources could be required to lockout one piece of equipment.
  • Ask more experienced employees to explain the different lockout locations and energy sources of each piece of equipment.
