Personal Protective Equipment for Safety of Employees...

Personal Protective Equipment for Safety of Employees Personal protective equipment (PPE) is the equipment or a device which is intended to be worn or otherwise used by an employee at work and which protects the employee against one or more risks arising from the operation to the employee’s safety or health. It includes any addition or accessory to the equipment designed to meet a similar objective. It protects the employee from hazards and any harmful conditions (existing and potential) which may result in injury, illness, or possibly fatal injury. PPE can be an item worn on the body, such as gloves, or a device, such as a protective shield or barrier. Besides face shields, safety glasses, helmets, and safety shoes, personal protective equipment also includes a variety of devices and garments such as goggles, coveralls, gloves, vests, earplugs, and respirators. Examples of some of the personal protective equipments are given in Fig 1. Fig 1 Examples of personal protective equipments PPE is an important means of preventing work injuries. Ideally, the best approach is to maintain a safe work environment and eliminate any potential hazards. PPE is only to be relied upon as a last line of defense in places where it is not practicable to control the hazards at source. PPE is designed to protect the employee from serious workplace injuries or illnesses resulting from contact with chemical, radiological, physical, electrical, mechanical, or other workplace hazards. It is one of the ways to protect employees. However, it does not eliminate or reduce the hazard. It only places a barrier between the employee and the hazard. If the PPE fails or is not used, then the employee is not protected from the hazard. The use of PPE generally implies working in a potentially hazardous...

Determination of Product Cost in a Steel Plant...

Determination of Product Cost in a Steel Plant The term ‘product cost’ means the amount of expenses [actual or notional] incurred on or attributable to the production of the specified product. Product cost refers to the costs used to produce the product. It is the measurement in monetary terms of the amount of resources used for the purpose of production of the product. For effective monitoring, specific product cost (cost per unit of product produced) is usually determined. A steel plant consists of several processes which are integrated. These processes produce many intermediate products as well as semi-finished and finished products. Many of intermediate products and semi-finished products along with all the finished products are saleable products. There are also a large number of by-products which are being produced from these processes. These by-products are used either internally within the plant or are being sold to different customers. In such a situation, the cost of the saleable products is determined in the steel plant in several stages. Each stage has a product for which the cost is determined. This product may be a saleable product or may be an intermediate product used as a raw material for the next stage. In case the intermediate product of a certain stage is the raw material for next stage then the determined cost of the product along with the cost of handling losses for the product is assigned to the next stage to the extent the product is consumed in the next stage. The product cost in a steel plant is determined the way it is done in any other manufacturing organization. The total cost of producing a product basically consists of two components (Fig 1) namely (i) fixed cost, and (ii) variable cost. Fig 1 Component of...

Steel Scrap and Scrap Sorting and Preparation Processes Jan23

Steel Scrap and Scrap Sorting and Preparation Processes...

Steel Scrap and Scrap Sorting and Preparation Processes Recycling of steel scrap is receiving increased impetus these days due to the focus of an emerging environmental initiative since the increased consumption of scrap reduces the needs for additional resource extraction and hence reduces the environmental impact. Recycling of steel scrap is also a part of wise management of iron resources. Recovery of 1 metric ton of steel from scrap conserves iron ore, coal, and limestone.  As per the world steel association, the integrated steelmaking route, based on the blast furnace (BF) and basic oxygen furnace (BOF), uses 1,400 kg of iron ore, 800 kg of coal, 300 kg of limestone, and 120 kg of recycled steel to produce 1,000 kg of crude steel and the electric arc furnace (EAF) route on average uses 880 kg of recycled steel combined with varying amounts of other sources (DRI, hot metal, and granulated iron), 16 kg of coal and 64 kg of limestone, to produce 1,000 kg of crude steel.  On an average, recovery of 1 ton of steel from scrap conserves an estimated 1,030 kg of iron ore, 580 kg of coal, and 50 kg of limestone. Steel scrap recycling also saves the energy consumption.  In the production of steel, 99.9 % of scrap melted is consumed in the production of new steel while producing negligible environmentally undesirable waste. Steel scrap is classified in three main categories namely (i) home scrap, (ii) new scrap, and (iii) old scrap depending on when it becomes scrap in its life cycle. Home scrap is the internally generated scrap during the manufacturing of the new steel products in the steel plants. It is also known as runaround scrap and is the material in the form of trimmings or rejects generated...

Ferrous Scrap and its Collection and Recycling...

Ferrous Scrap and its Collection and Recycling Ferrous scrap also referred to as, iron and steel scrap, or simply scrap comes from end of life products (old or obsolete scrap) as well as scrap generated from the manufacturing process (new, prime or prompt scrap). It is metal that contains iron. Iron and steel scrap can be processed and re-melted repeatedly to form new products. Due to the value of metal in the ferrous scrap, it is recycled or reused wherever it is possible.  In fact, ferrous scrap is being recycled long before current awareness of environmental concerns started. Ferrous scrap is generated during the production of iron and steel, fabrication or manufacture of iron and steel products, or when the product made of iron and steel reaches its end of life. Due to the high value of the metal, the ferrous scrap is largely being recovered. Given the chemical and physical properties of the material, iron and steel produced from ferrous scrap can, in almost all applications, compete with primary iron and steel produced from ore. However the amount of scrap collected and finally recovered depends on many factors, such as the collection system, the possibility and techniques used for the collection, etc. as well as a variety of legislation. The main sources for ferrous scrap are those products, for which iron and steel is the main constituent. These are namely, vehicles (including ships and rail coaches and wagons), products of construction, machinery, electrical and electronic equipment, and packaging etc. There is a difference between carbon steel scrap and stainless steel scrap since the carbon steel differs from stainless steel by composition and treatment. Carbon steel scrap is mainly used for the production of steel in induction furnace (IF), electric arc furnace (EAF) and partly...

Employee Relationship Management...

Employee Relationship Management Employees are the major assets of an organization. They are among the organization’s most important audiences with the potential to be its most effective ambassadors. It is essential that the employees perform together as a collective unit and contribute equally towards the realization of a common goal. Employees share a certain relationship with their colleagues at the workplace. The relationship which the employees can have can be between co-employees, supervisors, managers and higher management. It is important that the employees share a healthy relationship for delivering their best performances. Employees are the focal point of an organization during its journey towards success. If the employees work together and share a good relationship with management then the organization achieves its tasks and objectives much faster. Management of the employee relationship is both important and valuable for the organization in the achievement of the competitive advantage. It is necessary to have a strong relationship between employees as well as between employees and management since it leads to better organizational productivity and performance. Employee relationship management (ERM) is a term which refers to relationship development and management between the organizational management and the employees. There are a lot of different issues in ERM which can affect employee satisfaction and which has a direct result on employees’ productivity and overall corporate culture. ERM refers to managing the relation between the different employees of the organization. The relationship can be between employee and the management as well as between employees at the same level. It is nothing but a technique which brings employees and management together on a common platform and guides them so that the organization achieves the desired targets without fighting with each other. In a layman’s language, ERM is nothing but managing interaction...
