HAZARD ASSESSMENT AND ITS CONTROL IN BULK MATERIAL HANDLING PROCESS OF AN INTEGRATED STEEL PLANT
Abstract – The proliferation of conveyor systems in various industrial sectors has fueled a growing demand for conveyors that surpass the capabilities ofconventionalsystems.Theneed to transport bulk materials over longer distances at higher speeds and with greater efficiency has necessitated the development of a comprehensive and safe working methodology.
However, the widespread use of conveyor systems has sometimes led to overlooking potential hazards and hazardous activities, putting workersatriskoffatalaccidents. To address this, it is imperative to continuously monitor all activities and identify potential hazards through a Hazard Identification and Risk Assessment with Controls (HIRA) approach. This research aims to determine the hazards associated with various activities of conveyor systems using HIRA andensure a safer workingenvironmentforallinvolved. The implementationof increasinglycomplexconveyorsystems without a thorough understanding of the system can result in inefficiencies and decreased productivity. This study seeks to address this issue by identifying hazards through HIRA and creatingstandard operatingproceduresfordifferentmaterial handling activities. The conclusions drawn from this research will provide valuable insights and offer recommendations for future work to further enhance the safety and efficiency of conveyor systems.

1. INTRODUCTION
The steel industry is a highly sophisticated and technologically advanced sector, characterized by interdependentmaterialflowsandrevenuestreams.Itisa crucial productinthemodernworld,witha widerangeof applications, from infrastructure building and industrial machinerytoconsumergoods.Theindustryisalsodiversein termsofthetechnologiesused,whicharedependentonthe natureandquantityofrawmaterialsutilized.InIndia,steel hasaprofoundimpactontheeconomy,witha1.4Xmultiplier effectonGDPanda6.8Xemploymentmultiplierfactor.
AtthetimeofIndia'sindependencein1947,thecountry onlyhadthreesteelplants-theTataIron&SteelCompany, theIndianIronandSteelCompany,andVisveswarayaIron&
SteelLtd-andahandfulofelectricarcfurnaceplants.Despite itssmallcapacityof1milliontonnes,thesteelindustrywas robust and entirely in private hands. Today, India is the second largest crude steel producer in the world and the largest producer of sponge iron, with the Iron and Steel Industrycontributing2%totheGrossDomesticProductand employingaround25lakhindividualsdirectlyorindirectly. The Indian steel industry, once with a negligible global presence,isnowrecognizedforitsproductquality,having successfully navigated the challenges of the businesscycle overitslonghistorysinceindependence.
In the year 2021, the global production of crude steel reachedastaggering1911.9milliontonnes,demonstratinga growthof3.6%comparedtothepreviousyear.TheWorld SteelAssociation'srankingsrevealedthatChinaemergedas the leading producer of crude steel, with a production of 1032.8milliontonnes,followedbyIndia,with118.1million tonnes,Japanwith96.3milliontonnesandtheUnitedStates with 86.0 million tonnes. The per capita finished steel consumptionin2020was228kgglobally,withChinaleading thewaywith691kg,whileIndiarecordedaconsumptionof 70kg.
In the domestic scenario, the Indian steel sector has enteredanewphaseofgrowth,followingde-regulation,asa result of the resurgence of the economy and increased demand for steel. This has led to a significant rise in production,andIndiaisnowthesecondlargestproducerof crudesteelintheworld,surpassingitspreviousthirdlargest status.Inaddition,IndiawasthelargestproducerofSponge Iron and the second largest consumer of finished steel globally, as per rankings released by the World Steel Association.
Ina de-regulatedandliberalizedmarketsuchasIndia,the role of the government is to act as a facilitator, providing policy guidelines and creating an institutional mechanism thatpromotesefficiencyandperformanceinthesteelsector. Inthisregard,theNationalSteelPolicy2017,releasedbythe government,outlinesthebroadroadmapforthelong-term growth of the Indian steel industry, both in demand and supply,by2030-31.Thegovernmenthasalsointroduceda policythatprovidespreferencetodomesticallymanufactured ironandsteelproductsingovernmentprocurement.Table2 showstheproductiondataofIndiansteelindustryasshared byjointplantcommittee.Table3showsthedataonimport and export of total finished steel in the past five years respectively.

The powered pulley is known as the drive pulley, while the unpowered pulley is referred to as the idler. The Belt Conveyor system can be classified into two industrial categories, namely general material handling, which involves the transfer of boxes within a factory environment, and bulk material handling, which encompasses the transportation of industrial and agriculturalmaterialssuchascoal,grain,andmustardsacks, generally in outdoor settings. It is important to note that companies specializing in general material handling Belt Conveyors typically do not provide conveyors for bulk materialhandling.
Furthermore,theBeltConveyorhasseveralcommercial applications, including in grocery stores. The belt is
composed ofone or morelayers of material, whichcanbe made of rubber. The majority of belts used in general materialhandlinghavetwolayers,includingacarcasslayer, whichprovideslinearstrengthandshape,andacoverlayer.

5. RESULT
Hazard Identification, Risk Assessment and Control method of assessing hazards in a worksite is a comprehensiveandextensiveapproachaimingtomakethe workplace safe and healthy. However, due to the comprehensive, cumbersome and laborious nature of the approach, it is not possible to assess each activity or task duringthedifferentstagesofconveyorsystemTherefore,in thisresearchtheHazardIdentification,RiskAssessmentand Control method is applied to three major operations that involvesextensiveman-machineinteraction.Theoperations underassessmentare:
