The worker killed in a rock crusher in Swampscott Monday has been identified as Christopher Perry, 37, of Lynn.

Police were called to the scene of Aggregate Industries at 30 Danvers Road, Swampscott, at about 1 p.m. Monday for what the Essex District Attorney’s office in a brief statement described as “a problem in a rock rusher” suspended above the quarry.

Perry and another worker were cleaning the inside of the device “when an apparent mechanical malfunction occurred,” according to the DA’s office statement.

Perry was pronounced dead at the scene, while the other worker was not injured.

The incident is being investigated by State Police detectives assigned to the DA’s office, Swampscott Police, the federal Mine Safety and Health Administration and the Occupational Safety and Health Administration.

Aggregate Industries has been cited by OSHA 15 times in the past decade, and its parent company, Holcim US Inc., has been cited 25 times in the same period, according to an analysis of OSHA records by worker rights organization MassCOSH.

“It is especially discouraging to look back on the history of extensive warnings this company and its affiliates have received over the last decade, only to have those warnings culminate in this incredibly tragic and preventable event,” MassCOSH Chief of Strategy and Engagement Al Vega said in a statement Thursday, before the worker’s name was divulged.

A Holcim spokeswoman said that the investigation is ongoing by local authorities and that the company “will provide additional details as appropriate.”

“The safety of our employees and contractors, and the communities in which we live and work, are our top priority. We’d like to express our sincere condolences to the family of the individual who passed away at our Swampscott site,” said Holcim chief U.S. spokeswoman Lynn Safranek in a statement to the Herald. “This is a tragic and very difficult incident.”
