One opened sample was returned for evaluation.Visual inspection did not reveal product damage.The safety mechanism was found activated and the needle engaged inside.During functional testing, the needle was pushed out of the safety mechanism and the device was pull tested to measure the amount of force required to re-engage the needle into its safety mechanism.The amount of force was found to be out of manufacturing specification (0.5 lbf < x < 1.5 lbf).To test further, thirty-two units were taken from the production floor and pull tested.All samples were found to operate as intended; the force required to engage the safety mechanisms was in specification.The exact root cause for the returned sample's safety mechanism operating outside of specification could not exactly be determined; a potential cause is related to a supplier manufacturing issue.A supplier notification was issued to the product supplier notifying them of the received product complaint and a request to review current processes.In addition, production personnel were notified of the report to heighten awareness of this issue.
