Today is the first day of October. This means different things to different people. For some it means fall is here, the leaves change, and weather starts to get colder. For the U.S. Government, it means the beginning of a new fiscal year. The new fiscal year brings about new editions of the Codes of Federal Regulations (CFR). Updated every year, they are published and available for purchase starting in November. This is important because a cylinder requalifier needs to have on hand the latest regulations in order to satisfy the requirements of the U.S. Department of Transportation under section 180.205(a)(4). If you are party to a unannounced compliance inspection, one of the first questions a DOT enforcement inspector will ask during an audit is "show me your latest CFR book". If you show them a previous edition it could be a $600 - $1200.00 fine. Ensure that you are not out of compliance by procuring the latest edition when published.
