SUGGESTED EARLIER FEW GUIDE LINES TO AVOID ANY EVENTUALITY WHILE CARRYING OUT NEWCOMPOSITION & BACTCHES OF HIGHER CAPACITY IN OLD RUSSIAN MIXER. THE SUGGESTIONS ARE GIVEN BELOW
EQUIPMENT CLEARANCE SHOULD BE AUTHENTICATED BY PROJECT AUTHORITIES BEFORE CARRYING OUT ANY OPERATION .i.e FOR BOWL MOVEMENT, ROTATION OF BLADES, LEAKAGE IF ANY AT GLAND JOINTS, CLEANLINESS OF BOWL, VACUUM APPLICATION AND CIRCULATION OF HOT/COLD WATER IN JACKET ETC
ACCEPTED RAW MATERIAL SHOULD BE WEIGHED IN PRESENCE OF QARD REPRESENTATIVE AND SEALED
ENSURING ALL OPERATIONS ARE CARRIED OUT AS PER LAID DOWN SOP AND IN PRESENCE OF QARD REPRESENTATIVE.
ASCERTAINING THE TEMPERATURE OF SLURRY NOT EXCEEDING 35 DEGREE CENTIGRADE.
AFTER MIXING IS OVER, IT SHOULD BE, CLOSED AND SEALED, BEFORE TAKING THE BOWL FOR NEXT DAY FOR CURATIVE ADDITION.
THE CURATIVE SHOULD BE WEIGHED AND ADDED IN PRESENCE OF QARD REPRESENTATIVE
BASED ON THE INSTRUCTIONS A NUMBER OF BATCHES WERE CARRIED UNDER THE SUPERVISION OF QARD REPRESENTATIVE IN THE MIXER WITHOUT ANY PROBLEM/ACCIDENT.. 3 AIR BOOSTER MOTOR AND A FEW AD-I MOTOR WERE CAST AND STATICALLY TEST FIRED W/O ANY PROBLEM.
LATER THESE ASPECTS ARE NOT CONSIDERED AND FOLLOWED
THE FOLLOWING FACTS TO TAKEN IN TO CONSIDERATION:-
QARD HAS TO BE GIVEN FULL AUTHORITY, EVEN TO STOP THE PROCEEDINGS IF ANY DEVIATION IS OBSERVED.
PROJECT IS NOT PREPARED TO ACCEPT THE SUGGESTIONS MADE BY QARD DIVISION. IT INSISTED THAT NDT SHOULD NOT BE WITH PROJECT. DECISION i.e. SENTENCING MOTOR/PROPELLANT FOR NDT CLEARANCE WILL GO IN PROJECT FAVOUR. BUT UNFORTUNATELY IT IS NOW UNDER SRP.
PROJECT IS NOT PROVIDING THE DETAILS OF CHANGES THAT HAS BEEN MADE /INCORPORATED IN THE COMPOSITION TO QARD AND HIDING THE FACTS. FREQUENTLY CARRYING OUT DIFFERENT TRIALS BY CHANGING COMPOSITION AND NOT MENTIONING THE ACTUAL FACTS
WHETHER SAME SOURCE OF RAW MATERIAL IS UTILISED IN THE BATCH, WHICH WENT OFF RECENTLY. EVEN CHANGE OF SOURCE OF RAW MATERIALIS IS ALSO TO BE CONSIDERED FOR ACCIDENT PURPOSE
WHETHER SOLID INGREDIENTS AND BINDER QUANTITY ARE CORECTLY WEIGHED AS PER THE COMPOSITION AND ADDED & AUTHENTICATED BY SCIENTIST
ANY POSSIBILITY OF FOREIGN MATERIAL ENTERING THE BOWL AT THE TIME OF ADDITION OF ALUMINIUM AND AMMONIUM PERCHLORATE WHICH WAS OVERLOOKED/NOTICED
WHETHER VACUUM APPLIED DURING MIXING AND RECORDED
WHETHER TEMPERATURE OF SLUURY AND RPM OF STIRRER RECORDED AND WELL WITHIN THE SPECIFIED LIMIT
ANY QA REPESENTATIVE EITHER HEMRL/OCRI WERE PRESENT AT THE TIME OF MIXING AND INTIMATED WELL IN ADVANCE BY PROJECT
THE MIXER WAS NOT OPERATIONAL QUITE SOME PERIOD. WHAT WAS THE PERIODICITY OF MAITENNANCE WITH SUPPORTED DOCUMENT EVIDENCE FROM PROJECT SIDE
THE COMMITTEE THAT HAS BEEN FORMED TO LOOK IN TO THE ASPECTS AND PROVIDE THE DETAILS IN THE ACCIDENT REPORT. THE REPORT TO BE MADE PUBLIC. OTHERWISE IT WILL BE SOUGHT THROUGH RTI
PROJECT IS NOT GIVING ANY IMPORTANCE/ WEIGHTAGE TO SUGGESTION BROUGHT BY QARD, . IT WAS BROUGHT BY QARD TO THE NOTICE OF PROJECT PEOPLE THAT AT THE TIME OF ADDITION OF FINE ALUMINIUM AND FINE AP, THE DUST PARTICLES STICK TO THE METAL SURFACES AND OCCUPY IN THE SPACE AVAILABLE AT THE TOP SURFACE OF BLADES. PROJECT HAS NOT GIVEN ANY IMPOTANCE/COSIDERATION TO THIS ASPECT. THE SUGGESTIONS WERE SUBMITTED TO SRP FOR THEIR CONSIDERATION WHILE CARRYING OUT THE MIXING .THE ACCUMULATION OF FINE DUST PARTICLES MAY LEAD TO FRICTION ANF FIRE AND DEVOLOPMENT OF GASES IN THE CONFINED BOWL WHICH LEAD TO DETONATION AND SERIOUS ACCIDENT
ADDITION OF SOLID INGREDIENTS TO BE INCREMENTAL AND SLOWLY. BUT DUE TO HURRY AND HAVING THE MINDSETUP TO FINISH THE OPERATION QUICKLY, LEAD TO RISK AND ACCIDENT/
THE LIFE OF TECHNICAL STAFF/OFFICER SHOULD NOT BE AT THE COST NEGLICENCE, IRRESPONSIBILITY OF SENIOR OFFICIAL AND POOR MANAGEMENT.
