BOISE, Idaho (AP) - Federal investigators have started looking into a weekend explosion at a hazardous waste site south of Boise, Idaho, that killed one worker and injured three others.

The explosion occurred Saturday morning at a US Ecology site about 50 miles south of Boise, and heavily damaged a building.

The company said in a press release Sunday that investigators from the Environmental Protection Agency and the Occupational Safety and Health Administration were on the scene, along with company officials.

US Ecology says 48-year-old Monte “Alex” Green of Grand View, Idaho, died of his injuries from the explosion.

The company says three other workers received treatment for non-life threatening injuries.

The company takes in contaminants such as arsenic, lead and other hazardous metals and converts them to non-hazardous residues.
