Event Description

The customer reports a cracked freezing bag 500 (7200600613).The bag was not investigated.A filled questionnaire and pictures were available.According to the questionnaire the following investigation and statements could be made: the event was observed during freezing/storage.The customer did use a metal cassette for freezing.No statement is made, if it was used for storage.A controlled rate freezer was used.An overwrap bag was not used.The filling volume was 100 ml (55-100 ml are recommended).The freezing bag was stored in the vapor phase of ln2.According to the pictures the freezing bag is cracked over the entire bag.The pictures show, that there was a big loose label attached to the freezing bag and was put onto the bag inside the metal cassette.The issue is likely caused by physical stress, e.G.Mechanical impact in combination with a wrong user handling.There are several deviations from the recommended freezing procedure.An overwrap bag was not used for freezing.Another deviation is the labeling.It is recommended to place an identification tag into the label pocket of the freezing bag.It cannot be excluded, that a loose label attached to the freezing bag and put into the metal cassette during freezing affect the product safety during the freezing process.A typical cause for this pattern of cracks is the presence of air bubbles.According to the pictures, in this case, no air bubbles are visible inside the freezing bag, but it cannot be ruled out.Air should absolutely be avoided in the sealed freezing bags as it will expand after during thaw and may cause a bag breakage.For the freezing bag 500 batch 7200600613, no deviation concerning the manufacturing process occurred.No anomalies occurred during the process.(b)(4).
