Two Iranian workers died and four were injured in an explosion at a paint factory west of Tehran.

Police officials say the explosion happened Wednesday night, originating in the factory’s raw material warehouse.

Labour activists have repeatedly spoken out against the lack of safety in workplaces and factories.

Labour sources report that according to Social Security Find statistics, at least 15,019 people under social security insurance coverage have been in workplace accidents in the past year.

ILNA reports that more than a thousand workers have become disabled in the past year due to workplace accidents caused by the lack of adequate safety tools, clothes or regulations.
