Aware date for the event was (b)(6) 2020, and the initial assessment of reportability concluded that the incident was not reportable.The instrument was returned to the manufacturer for investigation.The investigation shows small marks on the instrument cover, and on the power supply plug.The customer reported that when the incident happened the power supply was connected to the wall outlet before she attempted to insert the power supply into the instruments.The user manual for the instrument instructs the user to connect in the following order: - connect the power cable to the power cord adapter - insert the plug from the power cord adapter into the power socket in the back of the analyzer plug the power cord to wall a outlet.The connector at the low voltage end of the power supply is to be connected to the instrument.The investigation showed that it's highly likely that sparks occurred when the two poles on the power supply connector at the low voltage end of the power supply were shorted against the instrument cover at the back side of the instrument.Power supply fail-safe mechanism immediately disables the output voltage until short is removed.When short is removed, output voltage is enabled automatically.This mechanism limits the number of sparks.Testing has shown low likelihood of sparking representing a fire hazard.A medical review has since concluded that this incident was reportable in the event of harm.The incident is therefore reported as a conservative approach.
