Federal workplace safety officials have issued 25 serious citations and proposed $178,000 in penalties against a Fremont packaging manufacturer after a worker there suffered serious burns in February. The 25-year-old International Cushioning Co. worker's arm burns required a trip to the hospital, the U.S. Occupational Safety and Health Administration said in a statement. The company did not report the incident within the required 24 hours, the agency said, and the local fire department ultimately flagged federal officials about fire hazards at the plant. The plant, which opened in 2020, had already been facing seven other serious OSHA violations from 2021, records show. New Jersey-based International Cushioning makes several types of packaging including foam, bubble wrap, and cardboard products, according to its website. Company officials did not respond to a request for comment.
