Dollar General faces $1.68 million in fines for unsafe workplace conditions in four of its stores, the Occupational Safety and Health Administration (OSHA) announced Monday.

The chain has also been fined more than $9.6 million for similar worker safety issues since 2017. OSHA found the most recent violations during inspections in April at locations in Mobile and Grove Hill, Alabama; Tampa, Florida; and Dewy Rose, Georgia.

OSHA cited Dollar General for four willful and 10 repeat violations for failing to keep storage areas clean and stacking materials in an unsafe manner. The matter exposed workers to hazards associated with slips, trips and being struck-by objects, according to the release.

"Once again, our inspectors have found Dollar General stores ignoring federal safety standards and exposing their employees to hazardous working conditions in violation of the law," Assistant Secretary for Occupational Safety and Health Doug Parker said in the release.

"We will use our full enforcement powers to hold Dollar General accountable for its ongoing pattern of behavior until they show that they take worker safety seriously," Parker said.

Dollar General was also cited for various fire safety issues including fire hazards, improper fire exit routes, not enough fire extinguishers, among other violations.

Monday's proposed fines follow proposed $1.3 million in fines for Dollar General in August for workplace safety issues in Georgia.
