(29 November 2012)  OXYGEN INCIDENTS

Thus far in 2012 there have been in  excess of 430 incidents involving oxygen with the vast majority of them caused by careless handling of medical home oxygen use.  Thoughtless actions such as smoking and cooking at at gas stove while simultaneously breathing oxygen have caused scores of burns.  Extreme care must be taken to avoid all souires of fire while breathing oxygen.

(21 Sep 2011) PRESSED STEEL CYLINDER COMPANY

PST cylinder SP9791 (SU9294 in Canada) has renewed the special permit and these cylinders are authorized for use until 31 January 2015.

(21 Sep 2011)   INTERSPIRO DIVEATOR LITE CYLINDERS

This cylinder was originally approved and manufactured under DOT SP14209 but is now being manufactured as a UN cylinder under ISO standard 11119. Uniquely, the UN cylinder authorized for SCUBA use only requires a visual inspection at time of hydrostatic requalification.  Those SCUBA authorized cylinders manufactured under DOT SP 14209 still require an annual visual administered by a RIN holder.PST cylinder SP9791 (SU9424 in Canada) has renewed the special permit and these cylinders are authorized for use

(21 Sep 2011)   WORTHINGTON ALUMINUM CYLINDERS

In 2010 Worthington Cylinders purchases Hy-Mark Cylinders and began manufacturing aluminum cylinders in New Albany, Mississippi under a separate company called Worthington Aluminum Cylinders, LLC

(21 Feb 2009)  INSPECTING INTERSPIRO DIVEATOR CYLINDERS

Interspiro Diveator Lite cylinder SP-14209 is a unique carbon fiber cylinder with a non-load sharing plastic liner rather than aluminum one.   These cylinders require a yearly visual inspection that MUST BE CONDUCTED BY A RIN HOLDER.  The cylinders are for SCBA use unless marked on their label as being SCUBA cylinders.

(10 Sep 2008)  PSI Oxygen Cylinder Cleaning Technician Course

AT DEMA in Las Vegas, NV this October PSI will be introducing its exciting new training program for Oxygen Cylinder Cleaning Technician.  It has long been PSI policy that ALL EANx cylinders need to be properly cleaned for oxygen service.  Adding this course to the PSI Course catalog just made sense.  You can contact either me or PSI for more information on this new training program.

(10 Sep 2008)  New Training Requirement in Canada

Transport Canada regulation CSA-B340 5.1.2 requires personnel filling cylinders to be trained for that function.  This is Fill Station Operator training.  This same requirement is not as directly required in the US although title 49 of the Code of Federal Regulations does require personnel to have function specific training.

(27 July 2008)  Oxygen Cylinder Explosion

The explosion of an oxygen cylinder was apparently the cause of the hole that was ripped in the in the side of a Quantas Airlines Boeing 747 enroute to Manila.

(1 January 2008)  PSI 18-Step Inspection Protocol Modified

In order to comply with the new DOT regulation requiring all 6351 alloy aluminum cylinders to be eddy current tested at time of requalification, the PSI 18-Step Protocol has been modified to include administering an eddy current test when applicable.  If you are current as a PSI inspector, contact PSI for a copy of the revised version of the 18-Step Protocol.

(1 Jan 2007)  USDOT Reorganization

As part of a reorganization of the US Department of Transportation the Research and Special Projects Administration (RSPA) has been renamed the Pipeline and Hazardous Materials Safety Administration (PHMSA).  PHMSA has a wonderful web site (www.phmsa.dot.gov) that contains a wide variety of information on high pressure cylinders.

(1 Jan 2007)  VE MARKING

DOT requires all 6351 alloy aluminum cylinders to be eddy current tested by the hydro-requalifier at time of hydro and if the cylinder passes hydro, the eddy current test and the visual examination to be marked wit a VE following the requalification markings

(17 May 2006)  Luxfer Composite Cylinder Recall

Luxfer has made DOT aware that a total of 6,325 Luxfer FRP-1 composite cylinders manufactured May through September 2005 failed to undergo the required autoffrettage and hydrostatic tests and have been recalled by the company for proper testing.  These cylinders bear DOT-E 10915, DOT-E 9634, and DOT-E 9894 markings, but not all cylinders with such markings are recalled.  Specific serial numbers for the effected cylinders that have not yet been returned to Luxfer are contained in PHMSA Notice No, 06-02 as published in the federal Register on 1 May 2006 (http://hazmat.dot.gov/regs/notices/sa/71fr-25633.htm) or at www.luxfercylinders.com/ctest.  Once these cylinders have been properly and satisfactorily tested they will be returned to service.

(8 May 2006)  Oxygen Regulator Fires

     The National Institute for Occupational Safety and Health (NIOSH) has received 12 reports in which oxygen cylinders have burned or exploded causing, in some cases, personnel injury.  On 24 April they released an important advisory on this problem. The problem has to do with the sealing washers in oxygen cylinders.  You should immediately read this entire advisory.  You can find it at http://www.fda.gov/cdrh/safety/042406-o2fires.html    

(5 May 06)  6351 Alloy Cylinders

     There is a current controversy over whether or not aluminum cylinders made of 6351 alloy are safe to use and service.  The fact is that they are.  Competent authorities such as the CGA, OSHA, USDOT, and the manufacturers agree that these cylinders are safe to use and service so long as they remain within visual inspection and testing standards.  USDOT has also agreed that these cylinders should be slowly phased out of service and are considering a regulation to establish a 40 life span for 6351 alloy cylinders.  This ruling has not yet been codified.

Some businesses have made a purely business decision that they will no longer service or handle such cylinders.  They have every right to this decision and there is nothing wrong with it.  The business decision just cannot be defended by facts.

(19 Apr 06)  Pressed Steel Tank 

     The latest information on the PST E9791 situation is that the company, in the process of restructuring and moving, is also preparing  the documentation to renew the E9791 Special Permit which is set to expire in August 2007. Additional news articles can be found at www.psicylinders.com.  

(17 Apr 06)  EDDY Current Testing of Luxfer 6061

     Luxfer has approved the use of the Visual Plus 3 and the Visual Eddy Mark V eddy current testers for use on their proprietary 6061 alloy cylinders.  These machines have proven to solve the issue of false positive results when tested by the standard Visual Plus and Visual Eddy equipments.
