Last week, the FAA announced a $350,000 fine for Amazon after the retailer mishandled chemical shipments that resulted in injuries to UPS workers. Today, the agency hit the company with two more fines totaling $130,000 for similar incidents. In 2014, Amazon shipped separate packages, corrosive rust remover and a flammable gas used to clean air conditioners without properly labeling the boxes or sending along the required paperwork. Failure to do so violates the FAA's hazardous materials guidelines. The box containing Rid O' Rust Stain Preventer Acid leaked through, but there were no injuries reported.
