Fertilizer Manufacturer Fined $400K for Washington Worker Death from Toxic Gas

March 24, 2025

A fertilizer manufacturer has been fined $394,200 for the death of a worker killed by toxic gases at a work site.

The Washington State Department of Labor & Industries fined Two Rivers Terminal LLC for safety violations following the death of Viktor Voloshin, 56, at its Pasco facility.

On June 7, 2024, surveillance footage showed Voloshin entering a tanker truck to clean it, where toxic hydrogen sulfide gas from fertilizer residue killed him.

Voloshin, who worked for the company for 11 years, was also a father of 12.

L&I cited the company for multiple willful and repeat serious violations, including failing to provide air monitoring, ventilation, or protective equipment. Two Rivers Terminal, which has a reported history of safety infractions, is still appealing previous fines totaling $672,320.

The company is appealing the latest penalties. Fines go toward the workers’ compensation supplemental pension fund.
