Safety Management System in a Steel Plant A safety management system (SMS) is a systematic approach to managing safety, including the necessary organizational structures, accountabilities, policies and procedures. It is a systematic and explicit approach in the organization defining safety activities by which safety management is undertaken by the organizational management in order to achieve acceptable safety levels. It is a term used to refer to a comprehensive management system designed to manage the safety elements in the work place. Safety management system is a systematic approach designed to identify safety hazards and risks, control all safety elements and reduce the risks to a more acceptable manner by ensuring that the controls are effective. Safety manage system can be defined as “a businesslike approach to safety’. It is a systematic, explicit and comprehensive process for managing safety risks. As with all management systems, a safety management system provides a way for setting goals, planning, measuring the performance, control documentation and continues improvement. It becomes part of the culture, the way people do their jobs There are three imperatives for adopting a safety management system for the organization. These are ethical, legal and financial. There is an implied moral obligation placed on the management to ensure that the work activities and the place of work is safe. There are defined statutory requirements which are to be met effectively. Safety management system,  since reduces the risks in the work place,  can reduce the financial exposure of the organization by reducing the direct and the indirect costs associated with accident and incidents. To address these three important elements, an effective safety management system is to include the following. To define the organization which is set up to manage safety risks. To identify the workplace safety risks and implement suitable...

Methods of Shutting Down a Blast Furnace...

Methods of Shutting Down a Blast Furnace A blast furnace, after it is blown in and the production of hot metal starts, runs for a large number of years  before it is put down for relining. This continuous run of the blast furnace is known as campaign life. In modern blast furnaces  a campaign life of 15 years to 20 years is expected. When a furnace has reached the end of its campaign, it was usually blown out/blown down. Between the blown in to blown out/blown down, the blast furnace may have to be shut down for short periods due to various reasons. The various types of shut downs of a blast furnace are described below. (Fig 1) Fig 1 Important methods of shutting down a blast furnace  Fanning Very often while running of the blast furnace, a situation can arise when the full productive capacity of the furnace is not required for a period of time. This can be due to some problems which may arise in downstream or upstream facilities. When this occurs, the problem can be solved either by the shutting the blast furnace down or curtailing the operation of the blast furnace by reducing the quantity of hot blast. The hot blast rate is usually reduced until the hot blast pressure at the tuyeres is very low. However, it is a must that a positive pressure is kept in the hot blast system to assure that there is no danger of blast furnace gas coming back from the blast furnace into the blower system. The technique of reducing the hot blast volume to less than 20 % to 25 % of normal is known as fanning. Fanning has the advantages of keeping the blast furnace gas system pressurized and furnishing...
