Products manufactured according to substandard standards may inadvertently cause extensive injury or death to its owner, says Alabama liability attorney Keith T. Belt . Praxair, the manufacturer of a portable oxygen cylinder unit has recalled the product after discovering that fires could occur inside it, the FDA said. Praxair of Danbury, Conn., recalled all units of its Grab ‘n Go Portable Oxygen Cylinder manufactured from June 17, 2009, through Nov. 16, 2012. According to the FDA, fires within the cylinder unit may occur as a result of physical impact such as dropping or knocking it over and although the fires are self-extinguishing, they may expose patients to burns or deprive them of oxygen. In a statement, Praxair said it had been informed of “a few isolated incidents of ignition” and that they appeared to involve units with a certain type of O-ring that acts as a seal between the cylinder and the pressure-regulating valve. Praxair notified customers of the recall in a letter sent Nov. 26, 2012. It is being handled as a “field correction” with the device undergoing inspection and modification during regular servicing. “The unit is being inspected and, if necessary, the O-ring that sits between the valve and the cylinder is being replaced. To date, over 50% of the units in the U.S. already have been modified. Modified units have a decal with a ‘T’ affixed to their green shroud,” Praxair said. Praxair is making a minor modification to the affected units as they come in for routine servicing and filling. Praxair initiated this field correction after becoming aware of a few isolated incidents of ignition inside Grab ‘n Go oxygen cylinders that had been knocked over and subject to significant physical impact. Based on the preliminary results of Praxair’s review of these few incidents, it appears that Grab ‘n Go units fitted with certain equipment (a type of o-ring) may be more prone to this type of incident. Out of an abundance of caution to protect patient safety, Praxair has been making a minor modification to affected units. As units come in for routine servicing and filling, the unit is being inspected and, if necessary, the o-ring that sits between the valve and the cylinder is being replaced. To date, over 50% of the units in the United States already have been modified. Modified units have a decal with a “T” affixed to their green shroud. Praxair believes that the affected Grab ‘n Go units may be used safely if proper handling procedures are followed. It is important to practice safe storage and handling practices for the Grab ‘n Go cylinders to protect the cylinder from dropping, knocking over, or other significant physical impact.
