Soft shoulders on newly-constructed road lead to log truck rollover

Safety Alert Type: 
Resource Roads
Location: 
Greenwood, BC (Jewel Lake area)
Date of Incident / Close Call: 
2015-07-30
Company Name: 
Interfor - Grand Forks Division
Details of Incident / Close Call: 

A logging truck steered around a slight bedrock protrusion which caused the trailer to lean outward and track into the soft shoulder. The trailer rolled over the bank and pulled the truck onto its side.

Hazard: Recently constructed road with soft, powdery shoulders concealed a dip in the road’s subgrade.

Learnings and Suggestions: 

Actions to Prevent a Re-Occurrence:

  • Report potentially unsafe road conditions to your site supervisor.
  • Consider the use of a water truck and compacter when constructing roads in dry conditions, particularly when subgrade consists of fine textured soils.
  • Roads must be “set-up” and ready for hauling. If a road is too soft, narrow, has poor alignment or out-slopes, fix it before hauling starts.
  • Always stay alert while driving; even a slight distraction can have major repercussions.
  • Drivers must be cautious when hauling a new load configuration as this can alter the center of gravity and reduce truck stability.

Unseen snag tree in thick canopy impacts excavator during trail construction

Safety Alert Type: 
Heavy Equipment
Location: 
Albert Canyon resource road (east of Revelstoke, BC)
Date of Incident / Close Call: 
2015-05-19
Company Name: 
Downie Timber Ltd. - Woodlands
Details of Incident / Close Call: 

An excavator operator was constructing a pilot trail in the Albert Canyon area. The canopy was much heavier than “normal working conditions” as he was pushing a green tree in some very thick timber.

The green tree brushed up against a snag that was unseen by the operator from his cab. The top of the snag became dislodged when it was struck by the green tree and fell onto the hood of the machine. There were no injuries associated with this incident, however the machine was left with a dented engine hood and a broken off radio antenna.

Another worker in the vicinity who witnessed the incident attempted to grab the radio to alert the excavator operator but the broken snag fell too quickly. It was noted that snag trees were identified as a hazard in the pre-work for the job.

Immediate Cause: Inattention to surroundings – machine operator should not be working “blindly” in thick timber.

Basic Cause: Inadequate risk assessment; inadequate work standards or procedures

Root Cause: Inadequate standards

Learnings and Suggestions: 

Corrective Actions: Improve current Safe Work Procedures (SWP) to include the requirement for conducting daily site walk through assessments for snags and other hazards when working in thick timber.

Prevention Suggestions: The pre-work site assessment should have identified snags as a potential hazard of this particular locale and the issue communicated with the entire crew. A daily site assessment/walk through should be completed in heavy timber sites when conditions may have changed, to ensure that ALL hazards are identified.

Impatience behind the wheel leads to close call on public highway

Safety Alert Type: 
Paved Roads
Location: 
Big Bend Highway (north of Revelstoke, BC)
Date of Incident / Close Call: 
2015-07-28
Company Name: 
Downie Timber Ltd. - Woodlands
Details of Incident / Close Call: 

A worker was driving south on Highway 23 at the end of the day when he encountered a grader pulling a pick-up at a slow speed (estimated at 20 km/h). The worker followed the grader for a couple of kilometres and when a section of highway up ahead looked long enough to safely pass, he decided to overtake the grader with pick-up in tow.

Unfortunately, the worker chose to pass on a stretch of highway marked with a solid double line and on a long curve. While beside the grader, the worker's vehicle was met by an oncoming pick-up truck but managed to complete the passing manoeuvre and avoid a collision. The worker suggested there was "room to spare" but acknowledged the anger of the oncoming driver by way of a “gesture" directed at the worker.

Learnings and Suggestions: 

Immediate Cause: Illegal pass of slow moving vehicle.

Basic Cause: Poor judgement, failure to follow established rules.

Root cause: Inadequate risk assessment, inadequate compliance with standards.

Close Call: ATV loading incident

Safety Alert Type: 
Vehicles
Location: 
Pemberton, BC area
Date of Incident / Close Call: 
2015-06-22
Company Name: 
Chartwell Consultants Ltd.
Details of Incident / Close Call: 

Incident while loading an All-Terrain Vehicle onto a truck bed.

Quad failed to engage in 4x4 prior to loading onto truck, which caused the ramps to get kicked away from the truck, despite the fact that they were secured with cords. The driver of the quad was forced to quickly evacuate the unit, which landed on the tailgate of the truck, damaging the plastic liner.

No injuries were sustained and no damage was done to the ATV.

Learnings and Suggestions: 
  • Always ensure that the ATV is engaged in 4x4 before loading. If it won’t engage, use a winch to load the equipment.
  • 4x4 disengagement was the result of faulty circuitry – ensure regular maintenance is being done on all equipment and vehicles (ATV was immediately taken to the shop for repair).
  • Ensure that ramps are securely attached to truck or trailer, prior to loading.

Driver narrowly escapes serious injury from falling log

Safety Alert Type: 
Log Hauling
Location: 
Big Bar Area (central interior region)
Date of Incident / Close Call: 
2015-06-16
Company Name: 
Katchmar Construction (1997) Ltd.
Details of Incident / Close Call: 

A log truck driver backed his rig into the usual spot to take on his second load of logs that morning. The loaderman loaded the first bunk of the trailer and instructed the driver to pull ahead so he could start loading the second bunk.

The driver then exited his truck and went around the front of the truck to check the first bunk’s load. As the driver did this the loaderman was loading the second bunk. The driver then returned to the driver’s side of the cab and the loaderman honked to get his attention.

They then noticed two short logs had slipped through the frame rails on the middle bunk. As the driver walked beside the first bunk to check out the short logs in second bunk, the loaderman began picking up some of the logs in the second bunk, causing a rocking of the trailer as the driver walked along side.

A 4.4metre log up to 18cm’s in diameter fell approximately 4 metres from the top of the first bunk, brushing the driver’s hard hat and striking his left shoulder which knocked him to the ground.

The loaderman immediately noticed the truck driver on the ground and rushed to his aid. After assessing the driver (who was responsive throughout the incident), the loaderman helped him up then radioed for the supervisor as well as a coworker, who transported the driver to hospital. This serious incident could very easily have been far worse.

Learnings and Suggestions: 
  • Always have good communication between the loaderman and driver
  • Always follow safe work procedures-they are there for your safety
  • The driver needs to be in a safe zone while truck is being loaded with logs
  • Never load a truck or move the logs while the driver is in an unsafe location
  • When loading a truck be sure all logs are contained by the stakes
  • Regular safety meetings to ensure that all safe work procedures need to be met
  • Supervisor to initiate more observation

Log truck tips, spills load - Driver knocked unconscious, suffers neck/head injuries

Safety Alert Type: 
Log Hauling
Location: 
Echo Lake (west of Campbell River, BC)
Date of Incident / Close Call: 
2015-07-20
Company Name: 
Thibault Logging Ltd. / Critical Site Logging Inc.
Details of Incident / Close Call: 

It was mid-morning (approximately 10:00 a.m.) when a log truck tipped over spilling its load on Highway 28, adjacent to Echo Lake, 15 kilometres west of Campbell River.

The driver was knocked unconscious and suffered head and neck injuries. The incident is under investigation.

Learnings and Suggestions: 

The following reminders to truck drivers may or may not be related to the incident:

  • Be familiar with the truck operator’s manual and know its safety aspects.
  • Ensure commercial vehicle inspection is up to date on the tractor and trailer.
  • Conduct daily pre-trip inspections looking for mechanical defects or deficiencies.
  • Ensure cables, bunks, stakes, lift straps, couplings and other critical components are free of defects and in good working order. If damage is observed that can impact safe operation of the truck park it and have it fixed before using it again.
  • In addition to legally required brake checks, conduct “in service brake checks” each cycle and adjust as necessary.
  • Ensure you have an escape route (eg - the passenger door is unlocked before driving the truck).
  • Wear seatbelt whenever the vehicle is in motion.
  • Drive defensively and to road conditions. Abide by posted speed limits and drive defensively. Be wary of tourist traffic especially in the summer.
  • Do not accept an overweight, unbalanced or insecure load.
  • While in transit, stop and check load and tires periodically, especially before entering a public highway. Check cinches and tighten if necessary.
  • Listen for unusual sounds. Feel the braking and tracking response of the tractor and trailer. Stop and check if something doesn’t seem right.
  • Exercise extra caution on corners where incidents have occurred or where there is evidence of trucks having difficulty negotiating them.

Cougar encounter: big cat emerges from hiding, startles field worker

Safety Alert Type: 
Wildlife encounter
Location: 
Quilchena Area, 73km East of Merritt
Date of Incident / Close Call: 
2015-07-09
Company Name: 
Cabin Forestry Services
Details of Incident / Close Call: 

While a worker was traversing an NCD riparian feature, a cougar jumped out from behind a root wad and lands five metres in front of worker.

Cougar stared at worker and held its ground. Worker responded by pulling out bear spray and calling for co-worker that was nearby. Cougar backed off without taking eyes off worker.

Afterwards workers continued working together for the remainder of the day.

Learnings and Suggestions: 
  • Always carry bear spray.
  • Do not run. Flight might trigger pursuit.
  • Face the cougar. Don’t turn your back on a cougar. Stand up.
  • Maintain eye contact with the cougar. Cougars prefer to ambush prey from behind. If the cougar knows you have seen it, an attack is less likely.
  • If you are working with a partner or crew use your radio to notify them that you have encountered a cougar. Let others within radio contact know your situation and location.

Log falls on truck driver at de-wrap station

Safety Alert Type: 
Log Hauling
Location: 
Northern Interior Region
Date of Incident / Close Call: 
2015-06-29
Company Name: 
CANFOR
Details of Incident / Close Call: 

A truck driver was pulling his wraps at the de-wrap station when a log came down and struck him on the head.

The weighmaster and two other drivers responded before finding the driver lying on the ground unconscious.

The driver was transported to the hospital and was held for several hours before being released. The driver is unable to drive for a few days as a result of the concussion.

Learnings and Suggestions: 

Hazard:

• The driver hadn’t delivered to the log yard or used the particular de-wrap station in over a year.

• A shorter log was loaded on top of the load and not within the load, as per the log transportation procedures.

• The de-wrap station arms were resting against the trailer stake and not the load, which created room for the log to pass through and make contact with the driver (see photo).

Corrective actions to be taken:

• Log yard Supervisor will initiate more observations at the de-wrap station to ensure all safe work procedures are followed and equipment is used correctly.

• Contractor will review proper loading procedures with entire crew to ensure proper loading procedures are understood.

• Short logs must be contained within the bundle and not on top of the load.

• Drivers are responsible for the safety of the load before leaving the loader and before arriving at the scale.

• Incident will be reviewed with all drivers so they are aware of the risk associated when de-wrap arms are not resting against the load.

Mechanical Alert: Steering bracket failure on off-highway log truck

Safety Alert Type: 
Log Hauling
Location: 
Vancouver Island
Date of Incident / Close Call: 
2015-04-28
Company Name: 
Western Forest Products Inc.
Details of Incident / Close Call: 

A 1980 model Pacific P-16 off highway log truck was backing out of a fuelling site when the driver heard a bang. The driver noticed that his steering had stopped working.

Upon investigation, it was discovered the bracket that connects the steering ram to the draglink had broken. The failed bracket was supplied by a machine shop in Campbell River, BC. A bracket of the same design had failed a few months prior to this incident. However the supplier was unknown.

The manufacturer of the part did a failure analysis and found that the way the brackets were made could cause a premature failure. The bracket is now made in a different way and reinforced to avoid the failure (see photos in attached pdf).

Learnings and Suggestions: 
  • The steering brackets on all off-highway trucks with a Vickers Steering Ram on the driver’s side should be checked to see if they look like the failed bracket. The failed brackets have short gussets that do not extend past the bore for the draglink ball stud. They also have a tapered boss welded into the bottom plate for the ball stud to be anchored to.
  • These brackets with shorter gussets and welded-in ball stud bosses could have been made by different manufacturers over several years. If your truck has a steering bracket with shorter gussets it should be removed and replaced with a bracket that has been engineered to withstand the steering load of these trucks. Consult your Parts supplier for the correct bracket.
  • Brackets that have a solid 2” bottom plate that has the taper for the ball stud machined into it and has gussets that extend past the ball stud bore are proven in this application.
  • Any time a draglink steering bracket is removed it should be cleaned and inspected for cracks.

Attempt to remove key ring on water pump intake leads to sliced finger, stitches

Safety Alert Type: 
Firefighting
Location: 
Martin Mountain (near Monte Creek, BC)
Date of Incident / Close Call: 
2015-05-19
Company Name: 
Interfor (Adams Lake Div.)
Details of Incident / Close Call: 

Logging crew was actively fighting an operation fire. A supervisor (in a rushing state) was attempting to replace a non-functional water pump with a working one.

In the process of unbuckling the intake connection, the supervisor had to pull extremely hard on the key ring (he had no knife to cut the zap strap) to break the seal.

The key ring could not sustain the pulling force and quickly spread apart – the sharp end of the ring sliced through the supervisor’s middle finger. He was not wearing work gloves.

The supervisor required medical attention and received 3 stitches in his finger. He just missed cutting the tendons.

Learnings and Suggestions: 
  • Force yourself to slow down in high pressure situations. Give yourself time to think things through.
  • Always wear appropriate PPE (including work gloves).
  • Consider changing out key rings on suction hose intakes. Possible solutions could be zap-straps, nylon coated aircraft cable key rings, etc.
  • Consider always carrying a pocket tool (leatherman, knife, etc.)
