Federal workplace safety regulators have issued citations and fines against three businesses for violations in the deaths of six people last year at a Colorado dairy. The U.S. Occupational Safety and Health Administration announced penalties for the dairy owner, Prospect Ranch, and a dairy service provider, Fiske Inc's subsidiary High Plains Robotics, for failing to protect workers against hazardous gases that led to the deaths of five men and a teenager.
Why it matters
