In today’s mobile society, quick information access via mobile applications (app) has become the norm. In the transportation world that could include apps for airline flight schedules and mass transit routes. The US DOT Pipeline and Hazardous Materials Safety Administration (PHMSA) just rolled out an online Code of Federal Regulations (oCFR) mobile app to both its hazardous materials and pipeline safety regulations. This easy access to current U.S. DOT regulations by the general public, transportation stakeholders and emergency first responders will help advance the safe transportation of energy and other hazardous materials that are essential to our daily lives.
