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

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. |

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. |

inspector, contact PSI for a copy of the revised version
of the 18-Step Protocol. |

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. |

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

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. |

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

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. |

Luxfer
has approved the use of the Visual Plus 3 and the Visual
Eddy Mark V eddy current testers for use on their
