History

1959-1973

SAIL traces its origin to the Hindustan Steel Limited (HSL) which was set up on January 19, 1954. HSL was initially designed to manage only one plant that was coming up at Rourkela. For Bhilai and Durgapur Steel Plants, the preliminary work was done by the Iron and Steel Ministry. From April 1957, the supervision and control of these two steel plants were also transferred to Hindustan Steel. The registered office was originally in New Delhi. It moved to Calcutta in July 1956 and ultimately to Ranchi in December 1959.

A new steel company, Bokaro Steel Limited, was incorporated in January 1964 to construct and operate the steel plant at Bokaro. The 1 MT phases of Bhilai and Rourkela Steel Plants were completed by the end of December 1961. The 1 MT phase of Durgapur Steel Plant was completed in January 1962 after commissioning of the Wheel and Axle plant. The crude steel production of HSL went up from 1.58 MT (1959-60) to 1.6 MT. The second phase of Bhilai Steel Plant was completed in September 1967 after commissioning of the Wire Rod Mill. The last unit of the 1.8 MT phase of Rourkela - the Tandem Mill - was commissioned in February 1968, and the 1.6 MT stage of Durgapur Steel Plant was completed in August 1969 after commissioning of the Furnace in SMS. Thus, with the completion of the 2.5 MT stage at Bhilai, 1.8 MT at Rourkela and 1.6 MT at Durgapur, the total crude steel production capacity of HSL was raised to 3.7 MT in 1968-69 and subsequently to 4MT in 1972-73.

1973-present

The Ministry of Steel and Mines drafted a policy statement to evolve a new model for managing industry. The policy statement was presented to the Parliament on December 2, 1972. On this basis the concept of creating a holding company to manage inputs and outputs under one umbrella was mooted. This led to the formation of Steel Authority of India Ltd. The company, incorporated on January 24, 1973 with an authorized capital of Rs. 2000 crore, was made responsible for managing five integrated steel plants at Bhilai, Bokaro, Durgapur, Rourkela and Burnpur, the Alloy Steel Plant and the Salem Steel Plant. In 1978 SAIL was restructured as an operating company.

Since its inception, SAIL has been instrumental in laying a sound infrastructure for the industrial development of the country. Besides, it has immensely contributed to the development of technical and managerial expertise. It has triggered the secondary and tertiary waves of economic growth by continuously providing the inputs for the consuming industry.

SAIL today is one of the largest industrial entities in India. Its strength has been the diversified range of quality steel products catering to the domestic, as well as the export markets and a large pool of technical and professional expertise.

Ownership and Management

The Government of India owns about 86% of SAIL's equity and retains voting control of the Company. However, SAIL, by virtue of its ‘Navratna’ status, enjoys significant operational and financial autonomy.

Job analysis

Ergonomics:

``Adjustment of Man & Machine``

Ergonomics is defined as the science related to man and his work, embodying the anatomic, physiologic, and mechanical principles affecting the efficient use of human energy.

It is Application of human biological sciences with engineering science to achieve optimum mutual adjustment of man & his work, the benefit being measured in terms of human efficiency and well being.

Manual Handling (According to Ergonomics) –

Back Injuries:

All forces which come down the spine compresses discs and as a result of Continuous squeezing they can rupture and bulge causing severe pain. Most back injuries are built over along period of time by repetitive pounding on discs caused by improper methods. After sometime some minor lift can produce such rupture

``Straight back rule``

‘Thinking before lifting’

Control any risk by reducing necessity for manual handling by using

Alternative means of handling

*consider the load; size, awkward shape, etc*consider need for mechanical or manual assistance

*position legs apart - one foot level with the load*keep back straight, look up

*bend from the hips, avoid ‘twisting’ the body*tighten the stomach muscles, but don’t hold breath*BEND THE KNEES

*keep the load close to the body*lift with the legs, not the back*keep carrying distance short*avoid changing grip or ‘jerking’ the load*deposit the load by bending the knees and keeping the back straight

USER`S-ERGONOMIC GUIDELINES

SEATING POSITION

*Seat height to be adjusted so that thighs are horizontal & feet are resting flat on the floor*Thigh-torso angle is not less than 90 degrees, with 100 degrees as preferable*Chair should have ``Backrest’ with support for curvature in lumbar area
