sir,I am of 34 yrs(male) have undergone the open heart surgery on last dec.2010.It was the pericardial patch closure of ASD done by Dr. Devi shetty.The surgeon had used a stainless-steel wire to keep hold the rib-cage initially and advised me not nessary to remove it out and it will be inside for life time.Now as a metallurgical Engineer ,I am working in a high magnetic field area in an aluminium extraction plant.This magnetic field is created by high current(86000 amperes) passing through the conductors which is necessary for electrolysis process.All the iron and steel instruments being used for years in that area has been turned in to magnets. After working there for 15-20 days I felt that the wire is being magnetised gradually.This I tested by keeping the steel pins,blades ets on my chest.These are being sticked to the chest without dropping down.Secondly my job needs hard physical work in a heat and flourine exposure .I also feel migraine headache during duty period in left side only which lasts upto 2-2.5 hrs.please advice me wheather I could work there or it may give rise to any other problem in future.Otherwise I will request the management to change my department after getting the reply from you. manoj kumar rout(orissa)(mail - YYYY@YYYY )
