The Federal Motor Carrier Safety Administration (FMCSA), in conjunction with the Pipeline and Hazardous Materials Safety Administration (PHMSA), is issuing this safety advisory to provide notice of emergency discharge control equipment connected to and installed on cargo tank motor vehicles, which when improperly installed, do not operate correctly and can result in total loss of power to the cargo tank motor vehicle. This revised safety advisory updates and replaces the
previous advisory of the same title that was originally issued on November 25, 2015. Investigations conducted by PHMSA and the Railroad Commission of Texas identified cargo tanks in metered service transporting liquefied compressed gas to have improperly installed emergency discharge control equipment. Use of the improperly installed devices has resulted in unintentional shut down of the motor vehicle while in motion, resulting in loss of motive power, steering and braking functions.

Federal Motor Carrier Safety Administration (FMCSA) is issuing this safety advisory to provide notice to owners and operators of certain cargo tanks that they have been improperly inspected and tested, and must be re-inspected and retested before being used in Hazardous Materials specification tank service. The tanks in question were tested by H&W Tank Testing, CT#8083, Ohatchee, Alabama, and Christopher Humphries, CT#13131, Jacksonville, Alabama. Cargo tanks that have been inspected and/or tested by either company from April 2011 through March 2016, must be re-inspected and/or retested in accordance with 49 CFR § 180.407 immediately by a cargo tank facility registered with FMCSA.

The Federal Motor Carrier Safety Administration (FMCSA) is issuing this safety advisory concerning pressure relief devices (PRD) that were not manufactured or intended for use on cargo tank motor vehicles. PRDs are an integral part of the safety mechanisms for U.S. Department of Transportation (DOT) specification cargo tank motor vehicles and are vital to ensuring the safety of hazardous materials transportation by highway.  

The Ohio Department of Commerce, Division of State Fire Marshal (SFM) has recently completed training modules highlighting significant changes from the 2007 version to the 2011 version of the Ohio Fire Code (OFC). You can access the modules via links on the SFM’s website “2011 Ohio Fire Code Training Modules”. There you will find links to the International Code Council’s Campus (ICC) (where the modules are housed), a tutorial regarding how to create an account with the ICC and access the 2011 Ohio Fire Code Training Modules, and how to receive a certificate for completing the courses. There is also a technical support phone number for the ICC, and contact information for the SFM where you can provide feedback regarding the modules.

The Environmental Protection Agency (EPA) is amending its hazard categories in the regulations (40 CFR part 370) for reporting under Sections 311 and 312 of the Emergency Planning and Community Right-to-Know Act (EPCRA) due to the changes in the Occupational Safety and Health Administration (OSHA) Hazard Communication Standard (HCS).  OSHA's HCS was revised in 2012 to conform to the United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS).  Under the revised HCS, chemical manufacturers and importers are required to evaluate their chemicals according to the new criteria adopted from GHS to ensure that they are classified and labeled appropriately.  Manufacturers and importers are also required to develop standardized Safety Data Sheets (formerly known as "Material Safety Data Sheets/MSDS") and distribute them to downstream users of their chemicals.  These changes to OSHA's HCS affect the reporting requirements under sections 311 and 312 of EPCRA.

On October 31, 2012 at 6:00 p.m. while anhydrous ammonia (ammonia) field application assembly was making a turn at the end of the field, the hitch connection between the application/toolbar unit and the nurse tank failed. The break-away coupling device failed to disengage, causing the threaded fitting at one end of the withdrawal hose to fail resulting in the air release of ammonia. The video illustrates the ammonia release.
