Alberta Occupational Health and Safety officers are inspecting all sand and gravel crushing worksites in the province after two fatal accidents this year.

The province says it's trying to determine whether the industry still needs to improve its health and safety records.

OHS officers will be looking for worksite hazards, workers who lack necessary certifications, workers not wearing personal protective equipment and worksites without proper safeguards.

Officers can issue on-the-spot fines of up to $500 to employers and employees, an enforcement tool the province added this year.

“These inspections will shine a light on sand and gravel operators. I’m hopeful we’ll see improvement over last year’s performance, but recent tragedies certainly raise the question whether that’s the case,” said Kyle Fawcett, Alberta’s labour minister in a written release.

Last month, a 15-year-old boy was killed while operating a gravel crusher at a pit in Drumheller.

The teenager was still being trained at the time of the accident.

In a similar inspection blitz conducted by OHS last year,  the province said the worst violation discovered related to inadequate equipment guards.
