A Caesarstone Technologies employee was killed in an accident Monday at the company’s manufacturing plant in Richmond Hill, a spokeswoman said.

The worker’s name was not released.

“We can confirm that on Monday, February 6, 2023 an unfortunate accident occurred at our Richmond Hill facility ... which resulted in the loss of a valued Caesarstone employee,” Caesarstone’s Gail Conroy said in an email Wednesday. “We want to offer our sincerest condolences and support to the family, friends and co-workers affected by this incident.”

The plant, which manufactures quartz materials used in countertops, opened at the Belfast Commerce Centre in Richmond Hill in 2015. It employs an estimated 200 workers.

Conroy, the company’s vice president of marketing in North America, said Caesarstone officials have notified the Occupational Safety and Health Administration and that agency has begun looking into the incident.

“We are fully cooperating with local agencies and OSHA has been advised and commencing their review. In addition, we are taking multiple steps to support our employees including grief counseling along with full support to the affected family,” she said.

Caesarstone’s plant here has been the subject of three OSHA investigations since 2018, according to the agency’s online database. In one instance, an informal settlement was reached. In another, a citation was deleted and the most recent, from 2020, is being contested by Caesarstone.

Conroy said the company can’t say more while the accident is being looked into.

“With respect to the family’s wish for privacy and on-going investigation into the matter, there are no further details we can offer at this time,” she said. “But we want to reassure Caesarstone remains committed to the health and safety of all our employees at our plants, distribution centers and offices around the world. We will continue to adhere to the highest health and safety practices and always strive for continuous improvement to avoid such tragedies.”
