Event Description

Siemens became aware of an incident that occurred on the magnetom symphony unit.Siemens customer service engineer (cse) mounted the current lead into the magnet and checked the mag voltage to ramp down the system.The mag voltage was out of tolerance, therefore, the engineer tried to take out the current lead; during this activity a sudden system quench started.When quench occurred, the engineer tried to close the current lead port but lost consciousness (possibly due to low oxygen levels caused by high helium leak).The engineer fell down the magnet ladder to the floor and suffered a cold burn to the right hand as well as numbness and loss of sensation in his left leg.The cold burn was treated with antibiotic burn cream.A neurologist and orthopedist examined the left leg and performed an mri scan of the lumber.The engineer had to receive physical therapy following the incident.However, the treatment did not have the expected effect.The engineer continues to experience numbness and loss of sensation in the left leg.Therefore, it was decided to perform a surgery after the covid pandemic.The incident has already been investigated.The incident occurred due to a working error as the engineer did not wear the correct ppe (personal protection equipment).The reported incident occurred in (b)(6).
