NASHVILLE — Bridgestone Americas Inc. is investigating a Feb. 27 breach of its network that forced the company to disconnect computers and send workers home early from its U.S. production facilities.
"Out of an abundance of caution," the company disconnected computers at certain manufacturing and retreading facilities in North America and Latin America.
"Until we learn more from this investigation, we cannot determine with certainty the scope or nature of any potential incident, but we will continue to work diligently to address any potential issues that may affect our operations, our data, our teammates and our customers," the company said in a Feb. 28 statement.
Bridgestone sent workers home early from several manufacturing shifts spanning Feb. 27-28, including those in Des Moines, Iowa; and in La Vergne, Tenn.
According to media reports, Bridgestone workers have been affected at a truck and bus radial factory in Warren County, Tenn.; a passenger and light truck radial tire plant in Aiken County, S.C.; and Canadian media reported Feb. 27 that there was disruption to the night shift at a Bridgestone plant in Joliette, Quebec.
United Steelworkers Local 1155L, which represents Bridgestone employees at a truck and bus tire plant in Warren County posted on its Facebook page that workers' shifts on Monday were canceled at that location, as well.
