HAZARDS IN IRON & STEEL INDUSTRY

Iron and steel industry is a heavy industry, involving a whole range of processes-chemical, metallurgical, mechanical, electrical, construction, road and rail traffic, materials handling, earth moving, nucleonic and many others. Each of these processes has many in-built hazards, falling broadly into three categories.

  • Those that can be eliminated: e.g. leakages of gases, dust in motor house, pollution through plant chimneys, blazing of coke ovens, narrow workspaces, etc.
  • Those that can be controlled: e.g. noise level in pump houses and turbine halls, heat level in cast houses, dust level in sintering plant, gas concentration at working levels etc.
  • Those against which protective measures need to be taken i.e. those that can neither be controlled nor eliminated: Liquid hot metal (Heat and Glare), Noise in Rolling Mills.

    STACKING

    Stacking of rolled products should be done safely, to a safe height and leaving safe moving space in between the stacks so as to prevent sliding or toppling down of the pieces. No piece should project from the stack. Persons should not stand in close proximity to stacks, when pieces are being placed / the removed from these stacks. Magnet cranes are used for shifting rolled products from the cooling bed to the stacks stacks to wagons or on to the finishing beds. Persons should stand at a safe distance from these moving loads. The crane operators should ensure that during movement, the load does not fall with the stacks of materials. Persons should not stand in the wagons while loading finished products in to the wagons. Persons engaged in tilting of rails on the finishing beds should be very vigilant and ensure that the fork fits on the rail properly before applying pressure for tilting the rail. Slipping of fork can result in serious injure to the fork man.
    Stacking of coils should be done in a safe manner. During removal of coils for loading into the wagon, there is a grave hazard of slipping and falling down of adjacent coils. Persons engaged in supervising loading of coils should take a safe position anticipating the above hazard.
    After stacking merchant products, the sling ends should not be left dangling as during movement of crane these may get entangled with the stacks and hit the persons. The second loose eyes of the slings should also be put over the hook.

    INSTRUMENTATIONS AND PROCESS CONTROL

    Mechanical workshops; electrical repair shops; refrigeration and air-conditioning systems; electronic data processing systems; fire services; safety engg. Services and pollution control.

    1. PROJECT AND CONSTRUCTION DIVISION
    2. APPROACH TO HAZARD CONTROL



    One basic approach to any hazard control has been that in the first place, the hazard to be controlled has to be controlled has to be identified. A typical “safety hazards and emergency steps” should be studied. Such studies are made shop-wise and process control sheets are prepared indicating the hazards involved. Safety measures required and the safety appliances needed norms are to be taken from those prescribed under the factories act and rules, environment, water and air pollution act and rules.

    ABOUT TRAINING :

    Merely having updated safety books is not enough If these are to be strictly followed, regular on the job training is essential for the operation on the machines and producer and for the employees in there respective trade. Employees have also to be trained before they are put on the job whenever there is a change of trade or transfer to another department. This is necessary to acquaint themselves fully with the hazards of the new trade and new work place.

    IRON AND STEEL IT HAS THREE ZONES :

    Ø Gas holders and pipe lines.

    2. STEEL ZONE COMPRISING OF -

    Ø Steel melting shop
    Ø Continuous casting shop
    Ø Oxygen plant
    Ø Slag and scrap yard
    Ø Gas holders and pipelines

    3. ROLLING MILLS ZONE COMPRISING OF -

    Ø Different rolling mills,
