The second letter reads:

Important Notice-Action Required

We wish to advise you of an important addendum to the DuPont Tychem Level A garment inspection policy. DuPont is recommending that all Tychem Level A suits purchased from May 2002 through June 2007 need to have a valve diaphragm replaced.
The valve manufacturers, Auer and Pirelli, recommend routine replacement of the valve diaphragm every two years as part of routine maintenance.

To assist you in making this replacement, DuPont offers to provide, free of charge through October 1, 2007, valve diaphragms for Tychem Level A garments purchased between May 2002 and June 2007. This replacement does not apply to garments purchased prior to May 2002, as in accordance with Dupont recommendations on useful shelf life, these garments should be taken out of service and considered for training purposes only.

You may Contact Dupont Personal Protection directly to obtain the replacement Auer or Pirelli valve diaphragm free of charge through October 1, 2007

To obtain the free valve diaphragm from DuPont, the following information is required from you:

Dupont will have replacement diaphragms in stock within the next two weeks and will expedite shipment to you once the diaphragms are in stock.

As a reminder, as part of routine maintenance, DuPont requires inspection of Tychem Level A suits upon purchase, prior to each use and annually. These inspections should include pressure testing the garments and examining the valve diaphragm and zipper. This annual routine maintenance plan is the responsibility of the end user. Instructions on this routine maintenance plan are included in DuPont product literature and are also located on the DuPont website.
