A snowblower operator who lost his hand while clearing sidewalks in Charlottetown earlier this month was probably suffering from fatigue, says the Workers Compensation Board.

The worker was trying to clear snow that had jammed the blower when the accident happened, said George Stewart, director of occupational health and safety for the board. Stewart believes the man was tired and made a mistake.

"Probably fatigue was one of the contributing factors. These types of blowers, they plug regularly. That's one of the issues that they have with them," said Stewart.

Normal procedure in that situation, he said, is to shut the machine off, get out and unplug the blades.

"In his mind, and what he told us, he had shut the machine off," Stewart said.

The worker's hand could not be reattached.

The man will be eligible for worker's compensation, Stewart said.
