A worker cleaning a Raani Corp.chemical tank in llinois last year was burned over 80 percent of his body when by a 185-degree solution of water and citric acid – and his supervisor refused to call 911. Carlos Centeno arrived at Loyola Hospital Burn Center 98 minutes later – after having first been driven to a local occupational health clinic by a co-worker. He died of his injuries three weeks later.

The call from in from the Cook County (Illinois) medical examiner: a Raani Corp. worker had died from burn injuries caused by high-temperature water and a solution that erupted while the worker was beneath an open tank hatch.
