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.

Operator sustains injury as loader drops log, shakes violently

Safety Alert Type: 
Heavy Equipment
Location: 
Coastal Woodlands (Vancouver Island)
Date of Incident / Close Call: 
2019-01-09
Company Name: 
INTERFOR
Details of Incident / Close Call: 

A Front End Loader Operator sustained a serious cut between fingers, requiring surgery. The loader (966H) was travelling on a dry land sort carrying a very heavy load of 3 Hemlock logs (max. load or overweight). Operator was wearing seat belt.

The operator slowed and turned on the approach to a log bunk. Inertia caused the front of machine to dip with the grapple hitting pavement. The back end of loader lifted off the ground and the operator released a large log from the grapple. This caused the rear to abruptly drop.

The loader violently shook and the operator’s hand flung approximately 8 inches, catching a finger in a metal latch (originally hood latch type, with after market change made).

Learnings and Suggestions: 
  • Equipment must be inspected and records kept for unsafe working conditions. This includes: sharp objects, guarding, escape hatches and other safety devices, hazards from modifications, ergonomics and maintenance issues.
  • Manufacturer’s specified payloads must not be exceeded and operators must travel at safe speeds. Extra time is required to stop when carrying loads.
  • Supervisors must regularly observe equipment for care and control while logs are handled/moved.
  • Unsafe equipment must be locked out immediately, with repairs done and/or hazards removed prior to operating.

Pup trailer detached while leaving loading area

Safety Alert Type: 
Loading and Shipping
Location: 
Grand Forks Sawmill
Date of Incident / Close Call: 
2019-01-02
Company Name: 
INTERFOR
Details of Incident / Close Call: 

A driver entered the yard with his rear trailer on top of the front trailer and had attached the two trailers before he was loaded.

The fifth wheel had some accumulation of grit and ice which the driver tried to remove before attaching the trailer. After being loaded and driving forward 60 metres, the fifth wheel detached between the two trailers of the Super B and the rear trailer brakes locked up (photos in attached pdf).

The rear trailer slid 4 metres and stopped, resting on the landing gear. A post incident inspection determined that grit and ice in the locking mechanism prevented the “dogs” from fully locking into place and securing the connection.

Learnings and Suggestions: 
  • A Supervisor must complete a Hazard Assessment on trailers that are stacked and have to be attached before loading to ensure fifth wheel connections are free of debris
  • Trailers that are stacked must have their fifth wheel covered to prevent dirt and debris from building up on the locking mechanism.

Forklifts collide in lumber yard

Safety Alert Type: 
Heavy Equipment
Location: 
Chase, BC (Adams Lake Sawmill)
Date of Incident / Close Call: 
2018-12-19
Company Name: 
INTERFOR
Details of Incident / Close Call: 

Forklift 2 was loaded and travelling through a lumber yard in reverse heading towards the planer infeed. Forklift 2 came around a blind corner and collided with loaded forklift 1 who was travelling, also in reverse, into the lumber yard.

Forklift 2 collided into oncoming forklift 1’s load, narrowly avoiding a direct collision with the operator cab (see photos in attached pdf).

This incident had the potential for a head on collision at a combined relative speed of 36 km/h, as indicated on the dash cam footage of both forklifts.

Learnings and Suggestions: 
  • Lumber runways are not to encroach into roadways causing large blind spots
  • Slow down, stop, and look prior to proceeding around blind spots in lumber yards
  • Use additional care and attention when merging from secondary roadways to primary roadways
  • Drive at safe speeds! Loaded mobile equipment takes longer to slow down and stop
  • Maintain communication when entering congested areas
  • Outfit mobile equipment with blue lights or safety whips/flags for better visibility.

Forestry worker falls through ice while snowshoeing on a day off

Safety Alert Type: 
Other
Location: 
Wilson Lake (near Peachland, BC)
Date of Incident / Close Call: 
2019-01-06
Company Name: 
Gorman Bros. Lumber Ltd.
Details of Incident / Close Call: 

While enjoying a day off, a forestry worker fell through ice and into the lake. He was leading a group of people snowshoeing when he suddenly fell though the ice, ending up chest deep. He had crossed this same location many times throughout the years, but never had fallen through the ice. Fortunately, people in his group were able to reach him with their hands from the edge and pull him out.

It is not easy to extract yourself with snowshoes on and felt packs full of swamp water (not to mention feeling a bit panicky, as he could not touch the bottom). Had he been alone he quite possibly would not have been able to escape.

Another factor on his side was the outside temperature of minus -3. Any colder and the 1.5 kilometre walk out would have been dangerous, being soaking wet from the extremely cold water.

Learnings and Suggestions: 
  • Avoid waterways unless absolutely sure of ice conditions
  • Don’t trust any ice conditions when working alone
  • Always pack extra socks and some small plastic bags to put over your feet if they do get wet.

Lake Ice Conditions:

  • 7 cm (3 inches) or less - STAY OFF
  • 10 cm (4 inches) - ice fishing, walking, cross country skiing
  • 12 cm (5 inches) - one snowmobile or ATV
  • 20 - 30 cm (8 - 12 inches) - one car or small pickup truck • 30 - 38 cm (12 - 15 inches) - one medium truck (pickup or van)

Lift truck fork strikes kiln track, worker impacts steering assist knob

Safety Alert Type: 
Heavy Equipment
Location: 
Port Angeles, WA
Date of Incident / Close Call: 
2018-12-12
Company Name: 
INTERFOR
Details of Incident / Close Call: 

A lift truck traveling at 14.8 km/h stopped immediately when the right fork struck a kiln track. The operator’s chest impacted the steering assist knob. As a result, the employee was taken to the emergency room and diagnosed with internal bruising to the sternum area.

Learnings and Suggestions: 
  • Forklift operators need to know where their forks are at all times.
  • Forks should be carried approximately front axle height or a reasonable minimum distance from the operating surface (Hyster 155FT front axle height is about 16 inches high – this is at or below knee height and should be adjusted to a reasonable minimum distance).
  • Never travel with the mast tilted forward.
  • Make a production plan. A safe and acceptable production pace can be maintained to reduce pressure for crew members. Pre-staging or increasing manpower during fast product runs needs to be addressed before every production run.

Wagner strikes parked vehicle in log yard

Safety Alert Type: 
Log Sorting
Location: 
Grand Forks, BC
Date of Incident / Close Call: 
2018-12-10
Company Name: 
INTERFOR
Details of Incident / Close Call: 

A Wagner operator returned to the scale shack equipment cache in the Wagner to retrieve gear.

After retrieving the gear, the operator proceeded to run the Wagner north and out of the sample yard.

The operator lost track of a parked sand truck and made contact with the left drive tires of the Wagner causing significant damage to the parked vehicle.

Learnings and Suggestions: 
  • All mobile equipment must slow down, never rush, and wait for assistance if necessary. Meet with operators frequently to discuss rules of the log yard.
  • Log yard unloading cycle times must never take precedence over site safety!
  • In this log yard, parked vehicles or equipment will no longer be stored in close proximity to the Wagner’s normal travel route.
  • Should there be an upset condition, all equipment operators must request a hazard assessment be completed by a Supervisor prior to proceeding.
