Logging trucks in B.C. must be equipped with bullboards behind the cab. Bullboards—also known as cab guards or bulkhead guards—are intended to protect drivers from loads that might shift. Even when properly secured, a load of logs might strike and enter the cab during collisions or loss of control.
Bullboards must be properly designed and installed. However, over time they can weaken and begin to show signs of wear. Logging truck owner-operators, drivers, and employers should know how to recognize the signs of deteriorating strength—such as rust and cracked welds. Some logging truck companies have found that aluminum bullboards develop cracks more quickly than steel bullboards. Failing to thoroughly inspect and properly maintain bullboards can have fatal consequences.
Safe work practices:
- Ensure that all logging trucks are equipped with substantial barriers behind the cab. These barriers must be at least 15 cm (6 inches) higher than the cab and at least as wide as the cab. The barriers on self-loading logging trucks, however, can be just as high as—but no lower than—the cab.
- Ensure that bullboards are marked with a permanently affixed label or stamp or identified in an engineer's or manufacturer's letter that is carried in the truck. The stamp or letter must include the bullboard's model or serial number and its rated capacity in terms of cargo weight. The letter must include an accurate description of the bullboard and the manufacturer's or professional engineer's signature.
- Install bullboards according to one of these two methods acceptable to WorkSafeBC:
- Follow the manufacturer's instructions and any standard the bullboard must meet.
- Follow a professional engineer's specifications.
- Consult either the permanent label on the barrier itself or the professional engineer's letter stored in the logging truck for the truck's maximum acceptable cargo weight.
- Inspect bullboards regularly, paying close attention to the welds. Remedy any defects immediately. Ensure that repairs that may change the bullboard's rated capacity are certified by a professional engineer.
- Ensure that any modifications that may change the bullboard's rated capacity are certified by a professional engineer.
