Nitrogen kills sandblaster while wearing respirator hood (Pressure testing)

At 5:00 p.m. on February 4, 2021, an employee was working for a firm that manufactured fabricated structural metal. He was performing abrasive blasting with steel shot. He was wearing a supplied air respirator (SAR). While using the supplied air hood, he lost consciousness.

A pressure testing operation downstream on the plant airline allowed nitrogen to backfill into the compressed air line.

This test introduced an asphyxiant into the system.

The employee was killed.
