H6: investigation summary: scope of issue: the scope of issue is only limited to facscanto ivd 10 color configuration, part # 657338, serial # (b)(6).Problem statement: customer reported a complaint regarding a waste leakage not contained within the instrument.Manufacturing defect trend: there are zero qns (quality notifications) related to the reported issue.Date range from 03mar2021 to date 03mar2022.Complaint trend: there are 4 complaints related to the issue of a waste leakage not contained within the instrument.Date range from 03mar2021 to date 03mar2022.Manufacturing device history record (dhr) review: dhr part # 657338, serial # (b)(6), file # (b)(6), was reviewed.The instrument met all the manufacturing specifications prior to release.Investigation result / analysis: the investigation was performed and based on the review of the complaint trend, defect trend, dhr, risk analysis and servicemax, the root cause of the waste leakage not contained within the instrument was due to a worn waste probe and waste tank baffle.Tank baffles are flat plates attached to the inside of a tank that limit liquid movement and prevent swirling.The customer had initially reported the leakage from the wet cart and an fse (field service engineer) came onsite for the repair.The fse confirmed the leakage to be from a worn waste probe and replaced the part (pn 338978).The fse also found that the waste tank baffle was cracked and replaced that part as well (pn 33850507).No parts were requested for evaluation as the replaced parts are not returnable and were discarded.After the repair, the instrument was performing as expected with no further leaks.The part was not requested for evaluation because it is not returnable and was discarded.Although the leakage was of a biohazardous material, the customer confirmed that they did not come in contact with the leakage and were not harmed in any way.Additionally, the leakage was not under pressure and thus did not increase the risk of exposure.Proper daily and monthly cleaning and maintenance can help in preventing lowered performance of the system, and can be found in the bd facscanto flow cytometer instructions for use (ifu), #23-14730-03 rev.1/vers.A.The safety risk of this hazard has been identified to be within the acceptable level.Service max review: review of related work order #: (b)(4), case # (b)(4).Install date: (b)(6) 2013.Defective part number: 33850507 - baffle spa 10l waste tank ext - service, 338978 - snsr 2-level-sw 120vac 10.6in stem 7-pin.Work order notes: subject / reported: fluid under wet cart, problem description: fluid under wet cart.Work performed: found: 1) fluid under wet cart -top of waste probe is leaking - replaced waste probe 2) waste tank baffle is cracked - replaced waste tank baffle.Cause: 1) waste probe 2) waste tank baffle.Solution: instrument operating with in bd specifications.1.Was the leak contained within the instrument? no.2.Was the leak in a customer accessible location? yes.3.What was the fluid that leaked? waste.4.What is the source of leak -- waste line or non-waste line? waste line.5.Was the customer exposed to blood or bodily fluids? no.6.Was there any physical harm to the customer as a result of the leak? no.Returned sample evaluation: a return sample was not requested because the replaced parts are not returnable and were discarded.Risk analysis: risk management file part #335860-08ra, rev.08/vers.A, bd facscanto fluidics fmea was reviewed.No new hazards have been identified and the current mitigations are sufficient.Hazard(s) identified? yes, no.Item: 6.Waste tank, function: 6.1 contain waste, potential failure mode: 6.1.1 waste not contained, potential effect(s) of failure: 6.1.1.1 biohazard, potential cause(s)/mechanism(s) of failure: waste container overflows, current controls: level sensor, recommended actions: actions taken: n/a, initial severity: 9, initial occurrence: 2, initial detection: 1, rpn: 18.Mitigation(s) sufficient: yes, no.Root cause: based on the investigation results the root cause of the waste leakage not contained within the instrument was due to a worn waste probe and waste tank baffle.Conclusion: based on the investigation results the root cause of the waste leakage not contained within the instrument was due to a worn waste probe and waste tank baffle.The fse confirmed the issue and replaced the waste probe and waste tank baffle.After the repair, the instrument was rebooted, tested, and functioning as expected.No one was harmed or injured, and no medical treatment was performed due to the biohazardous leak.The safety risk of this hazard has been identified to be within the acceptable level.Supporting document: n/a h3 other text : see h10.
