Hannaford Supermarkets intends to implement new ergonomic standards at its South Portland distribution center in the wake of a federal safety investigation.

The Scarborough-based grocery chain agreed to hire an ergonomic consultant to improve safety in activities such as lifting boxes and wrapping pallets to reduce the risk of injury to its approximately 300 workers there.

“Hannaford worked closely with the Occupational Safety and Health Administration through the review process, and our team is pleased with the enhancements we have underway,” said company spokesman Eric Blom in an email. “We appreciate the collaboration with OSHA and its contribution to supporting a safe and productive workplace.”

A settlement was announced Wednesday by the federal Department of Labor between Hannaford and OSHA. After inspections in 2013 and 2014, OSHA cited Hannaford for failing to keep its Schodack Landing, New York, and South Portland distribution centers free from recognized hazards likely to cause musculoskeletal disorders, such as sprains and strains. Hannaford initially contested the citations, but reached a settlement July 20 to institute new worker protection safeguards at both distribution centers. The company also agreed to pay a $9,750 fine.

During the OSHA visits, federal inspectors observed workers leaning over too far before lifting heavy boxes and performing other tasks that could result in injuries. In addition to hiring an ergonomics consultant, the federal safety authority also recommended Hannaford revise some of its inventory selection practices and automate some of the packaging and delivery processes.
