The device history record (dhr) was not performed during this investigation as the lot number was not received with the complaint.All dhr¿s are reviewed and approved by quality prior to the release of the product.It is also important to note that a series of tests are performed during every lot of production.More specifically, inspections are performed to test the seal strength for both the inner seal, where the product would activate and the outer seal.During the test, the pouch is first activated, the inner seal is broken.The pouch is then placed between two plates.The pouch is compressed until the pressure required per the procedure is reached, 350 lbs.Minimum.The pouch is left to dwell in the machine for 20 seconds, using a calibrated stopwatch to time it.After the dwell time the pouch is removed and visually inspected for leaks or spreading of the seam.A pouch with any deficiency would be rejected at this time and the machine adjusted.If the pouch passes the dwell test it is returned to the machine and the pouch is the compressed until the pouch breaks or reaches over 1000 pounds.A sample in the form of a photo in the complaint report shows the heel warmer pouch and the hand and clothing of a person which are covered with the chemical mixture.While a definitive root cause could not be determined without a returned sample, a likely contributor for this issue is as the vertical sealer bar is sealing the top of two consecutive pouches, there could be a localized weak region just prior to the midpoint of the vertical sealer bar causing an incomplete seal.It is not always possible to immediately see the issue as one of the materials used is clear.It has been determined there are indicators within the manufacturing process which will assist in verifying the materials are lined up correctly.The results of the manufacturing facility investigation were able to identify the most probable cause of the condition is associated with the manufacturing process.A quality alert has been issued to heighten awareness of the operators and associates of what some of the indicators are of mis-aligned material.A formal corrective/preventative action has been opened to verify the root cause and determine actions to prevent recurrence of the issue.
