URGENT RECALL: DAN, Divers Alert Network LSP Oxygen Regulators

Feb 25, 2005 | Cyber Divers News Network

DAN, Divers Alert Network, has announced a recall of oxygen regulators it sold in the DAN Standard, Dual, Mini, Charter and Training Unit oxygen systems.

All oxygen regulators sold under the Life Support Products (LSP) brand are being recalled to replace aluminum components in the unit's high-pressure chamber with brass components. This action is being taken in response to reports of fires and explosions, the exact causes of which remain unknown.

Over the past five years the Food and Drug Administration has received 16 reports of aluminum regulators used with oxygen cylinders burning or exploding. These incident caused severe burns to 11 healthcare workers and patients.

DAN has sold two regulators that are affected by the recall. The two regulators (pictured) are the LSP 270-020 and the LSP 280-020. These regulators were sold in the DAN Standard, Dual, Mini, Charter and Training Unit oxygen systems from 1985-1997.

This recall does not affect the DAN Rescue Pak, Rescue Pak Plus and the regulators that are sold with those systems, the B & F Regulator (Part # 84025G) and the Allied Spectrum Regulator (Part # 32-29-5551).

The recall is being undertaken in cooperation with the United States Food and Drug Administration (FDA) to minimize a potential for fires and explosions, an inherent risk with any high-pressure oxygen delivery system.

In May 1997, Allied conducted a recall to add a sintered bronze filter to the regulator. All regulators should already be fitted with this sintered bronze filter.

Any regulators without a sintered bronze filter, and all regulators manufactured by LSP's predecessor corporation, Robertshaw Controls Company, Inc., should be taken out of service immediately.

If the regulator was bought after May 1997 or retrofitted pursuant to the May 1997 recall, the regulator should already have the sintered bronze filter installed.

This, in conjunction with present recall efforts, will result in the replacement of all-aluminum high-pressure parts with brass parts. This interim measure will enable the regulators to be used during the period required to manufacture non-aluminum regulators.

This information has been provided to the FDA. It is Allied's understanding that the FDA is recommending the elimination of all aluminum in oxygen regulators. Users can reduce the risk of oxygen fire and explosion by keeping in mind the following precautions:

The oxygen cylinder, cylinder valve and regulator should be free of all contaminants.

The cylinder valve should be opened slowly whenever the unit is used in order to minimize heat of rapid compression in the regulator.

Users who refill their own oxygen cylinders should take extra care to avoid the introduction of contaminants during the filling process.

DAN has established a relationship with Riley's Emergency Medical Repair Center Inc., an Allied authorized service center, that will be equipped to handle the recall within the next few weeks. DAN Members who have purchased any DAN Oxygen Unit will receive a mailing with details about how to have their regulators serviced.
