They make plastic lids for all kinds of bottles. Now the folks at the Berry Kerr Company in Hertford County can put the lid on a new award's case, showcasing their one million safe hour designation. In the last three years, there has not been one injury that resulted in a lost workday. For Berry Kerr's efforts, the North Carolina Department of Labor honored the company Thursday, in a safety milestone celebration. So how big a deal is this award? Well, more than 200,000 companies are regulated by the state labor department. Last year, only 88 received this honor.
