This chapter discusses various strategic and analytical tools for evaluating projects using net present value (NPV). It introduces corporate strategy and how positive NPV projects should increase share prices. Decision trees are presented as a way to model sequential decisions under uncertainty. Sensitivity analysis, scenario analysis, and break-even analysis allow examining how sensitive NPV is to changes in assumptions. Options related to projects, like expanding or delaying, are discussed as having value not captured in basic NPV calculations. The chapter concludes that a project's market value equals its NPV plus the value of embedded managerial flexibility options.
This document discusses incremental rate of return analysis for multiple alternatives. It explains that incremental analysis avoids inconsistent rankings that can occur when alternatives have different lives. Incremental cash flows are calculated as the difference between alternatives' cash flows. The rate of return for the incremental cash flows (Δi*) is computed and compared to the minimum acceptable rate of return to determine which alternative provides the higher return. The analysis can be done using present worth of incremental cash flows or using annual worth of total cash flows for one life cycle.
This document contains sample problems and solutions related to interest rates and time-money relationships. Some key points:
- Problems calculate simple and compound interest rates for various investment amounts and time periods.
- Questions determine future and present values of investments, loans, and annuities using compound interest formulas.
- Examples find equivalent uniform annual costs, retirement fund amounts, loan balances, and other financial calculations.
- Solutions walk through setting up and solving the compound interest and time value of money equations for each problem.
Chapter 8 - ROR Analysis for Multiple Alternatives.pptParmeshworVetwal1
This document discusses rate of return (ROR) analysis for multiple project alternatives. It emphasizes that incremental analysis is necessary to select the alternative with the highest overall ROR when capital is limited. The alternative with the highest ROR may not provide the best return if it ties up too much capital. The document provides steps for performing incremental ROR analysis between two alternatives and between multiple alternatives to identify the option with the highest overall ROR.
This document contains 18 math problems related to inflation and calculating present and future values with inflation adjustments. The problems cover topics like calculating cost per person for a sewage treatment plant adjusted for inflation, determining life insurance needs to provide a constant annual interest amount after accounting for inflation and interest rates, and calculating internal rates of return on investments when adjusting for inflation.
This document discusses various methods for comparing alternative investments or projects, including present worth analysis, annual cost analysis, rate of return analysis, benefit-cost analysis, and break-even analysis. It provides examples of how to use each method to evaluate alternatives and select the superior option. Specifically, it explains that present worth analysis is used to rank alternatives that are mutually exclusive and have the same lifetime, while annual cost analysis handles those with unequal lives. Rate of return and benefit-cost analysis can incorporate incremental analysis to evaluate pairs of alternatives.
This document discusses different methods for evaluating multiple investment alternatives:
1) For non-mutually exclusive alternatives, compute the ROR of each and select those above the MARR.
2) For mutually exclusive alternatives, rank by investment and use incremental analysis, accepting challengers if their ROR exceeds MARR.
3) Incremental analysis also applies when one of the alternatives is a "do nothing" option - select the alternative if its ROR exceeds MARR or the incremental ROR is above MARR.
This document summarizes a lecture on rate of return analysis for multiple alternatives. It covers calculating incremental cash flows, interpreting rates of return on extra investments, and evaluating alternatives using present worth and annual worth. Incremental analysis is necessary when alternatives have inconsistent rankings by present worth and rate of return due to different reinvestment assumptions. The key steps are to order alternatives by cost, calculate the incremental cash flow between each, and compute the rate of return to determine if the extra investment is worthwhile. If the incremental rate of return exceeds the discount rate, the higher cost alternative is preferred.
This document outlines incremental rate of return (ROR) analysis for evaluating multiple mutually exclusive alternatives. It discusses how incremental analysis is necessary when alternatives have different investment levels. The procedure involves ordering alternatives by investment size, calculating incremental cash flows between consecutive alternatives, and finding the incremental ROR to determine if moving to the higher investment alternative is worthwhile. If the incremental ROR exceeds the minimum acceptable rate of return, the higher alternative wins that round. This process continues round-by-round until a single preferred alternative emerges. An example applies this procedure to select the best among four alternatives.

Abstract: Due to rapid industrialization, industrial workers are exposed to several types of hazards and
accidents, every year lakh of workers are injured due to mechanical, chemical, electrical and radiation hazards
and it leads to partial or total disablement. So in recent years greater attention is given to health and safety to
protect the workers from the hazards present in the industry. The purpose of this study is to evaluate the safety
performance in cement industry. Cement workers are prone to the hazards and this has potential to cause injury
or illness. Because the nature of work, the working condition, the environment in which the employee exposed
are entirely different. Due to the heavy dust exposure the employees become victims of pulmonary disease. So
the employee has to be safe guarded by providing welfare, safety, training and performance appraisal measure to
improve their efficiency and productivity. This paper work intended to evaluate the safety performance of
cement industries.
Keywords: safety audit, HIRA, Cement industries hazards, Safety culture, Accident reporting, at risk behavior.
I. Introduction
Cement Industry is one of the largest industries of the world and occupies predominant place as one of
the basic industries for development and its employment generation capacity. India entered into the Cement Era
in 1914, when the Indian Cement Company Ltd started manufacturing Cement in Porbundar in Gujarat.
However, even before that a small cement factory was established in Madras in 1904 by a company named
South India Industrial Ltd. Indian Cement Company Ltd produced only one type of cement which was designed
by the British standard committee as “Artificial Portland Cement”. Cement is used globally for construction, and
its raw materials are lime, silica and alumina. Cement is a binding agent that gives hardness and binds different
construction materials together and it is a major constituent of concrete. Cement is an essential component of
infrastructure development and most important input of construction industry, particularly in the government’s
infrastructure and housing programs, which are necessary for the country’s socioeconomic growth and
development. It is also the second most consumed material on the planet. The Indian cement industry is the
second largest producer of cement in the world.
II. Hazards of Cement Production
The manufacturing of cement is a long process and at every stage of its production, the environment is
affected in one way or another. Carbon emissions, water pollution, and release of heavy metals in the air are
common problems associated with manufacturing of cement. Fine cement dust is major pollutant and irritant
that not only affects the health of people, but also harms plants. Chronic diseases and respiratory disorders are
observed in people who work in a cement industry and are exposed to the cement constituent and cement dust.
The setting of cement is a long term process and it is alkaline in nature, which may lead to lung and skin
disorders because of the excessive heat normally released during setting and curing. Ensuring healthy and safe
working conditions for employees and contractors is a fundamental key to corporate social responsibility, and
one of the most important issues for the cement industry. Exposure to cement dust can irritate eyes, nose, throat
and the upper respiratory systems. Skin contact may result in moderate irritation to thickening/ cracking of skin
to severe skin damage from chemical burns. Silica exposure can lead to lung injuries including silicosis and lung
cancer. Exposure to wet concrete can result with long sleeves and full length pants, waterproof boots and eye
protection. Unguarded machinery used in the manufacturing process can lead to worker injuries. Workers may
be hit by falling objects from conveyor belt systems, elevators or concrete block stacking equipment. Improper
lifting, awkward postures and repetitive motions can lead to sprains, strains and other musculoskeletal disorders.
III. Litreature Review
Karl-Chiristian Nordby (2016) et al have examined the relationships and established conversion factors
between total dust Respirable, thoracic and inhalable aerosol fractions measured by parallel personal sampling
on workers from the production department of cement plants. The median ratio between the observed results of

the Respirable “total dust” and inhalable fractions relative to the thoracic aerosols fraction were 0.5, 2.4, and 5.9
respectively. Chaib Rachid (2015) et al has presented a case study about Safety and health at work in Algeria
cement plant. Occupational safety and health has become public health priority in industrialized countries and a
primary concern in the context of human resource management and in particular high risk industries. This work
is an opportunity to initiate a goal approach to prevention in cement plant whose purpose is to improve working
condition by technical, organizational, and human solution to improve the health and safety of employee while
engaging in the process of continuous improvement. A.M.Tungu (2014) has assessed changes in respiratory
health among cement workers and unexposed controls after 1 year in a factory implementing a health and safety
campaign with the main aim to increase use of personal protective equipment. The prevalence of respiratory
symptoms among cement workers was reduced after 1 year of follow-up following an intervention campaign to
improve use of personal protective equipment. Meenesh Kummari Tomar (2014) has studied Health, Safety and
Environment related problems in the cement industry. Data is being collected for different activities and
processes of cement manufacturing. Questionnaires and checklists were being used for the study. Occupational,
health and safety aspects were being monitored in the industry. Industry is well equipped with all the necessary
PPE’s required by the workers. Syed Sana Mehraj (2013) et al has said cement industry production is being
recognized to play a hazardous role in the imbalance of the environment and producing air pollutants in the form
of various oxides particulate matter as well as heavy metals which pose a serious threat to living world including
humans, plants, animals, live stock etc. The main route of entry of the cement dust particles in the body is the
respiratory tract and gastrointestinal tract by inhalation or swallowing.

4.1 SAFETY AUDIT
Safety auditing is a core safety management activity, providing a means of identifying potential problems
before they have an impact on safety. Periodically safety audit and inspection is conducted periodically on
India cements for different sections namely
1. Lifting tools and tackles – once in a year
2. Pressure vessels – once in six months
(Specifically for pressure vessel they conduct ultrasonic test – once in Four years).
3. Belt convey – once in a year
4. Building stability – once in three year
5. Safety belt – once in six months
6. Passenger lifts – once in 6 months
7. Factory license & Fire license – once in a year
8. HSDS license – one time license.
4.2 Hazard Identifiacation and Ranking
In cement industry various hazards were find out during auditing. Various hazards were sort out in
various areas and required measure need to eliminate the hazards was recommended to the management.
4.3 Limestone Yard
Lime stone were stored in the yard which placed at left corner end of the cement industry. Huge lime
stone were stored in the yard for the cement manufacturing process. Heavy trucks are running in the yard for
loading and unloading the lime stone. Enormous amount of dust were present in the yard. During transportation
lime stone from the yard to the crusher dust will be high. The dust in the yard cannot be controlled, instead of
controlling the dust water can be sprayed in droplet form to avoid the spread if dust in the atmosphere. Yard
storage area have uneven floor which cause the heavy truck to get upset while transportation. Necessary nose

mask and hard cat must be issued to the workers working in the lime stone yard. Trucks drivers must attend the
training program and should know the operation of the vehicle.
4.4 Crusher Area
Crusher area present next to the lime stone yard. The lime stone were place in the crusher by the trucks,
by lifting up the truck carrier. Vibration and noise was high in the crusher area which can’t be avoided, instead
of that required ear muff and hard cat should be provided to the workers. The barrier guard near the crusher is
damaged and it is in dangerous condition, which needs to be replaced. The lime stone powder was spilled over
the crusher area which will fly when heavy air passed it creates the dusty environment.
4.5 Conveyor Belt
The conveyor belt which used for transporting the cement from one to another place has spillage over
the area near the silo. The spillage needs to be cleaned in short time period, over spillage of material will cause
problem in maintenance time and it will cover the floor area which creates hazardous environment near the
conveyor area. The conveyor areas before the silo has low lighting were the area is not clearly visible. Adequate
lighting must be done in the area for the clear vision.
4.6 Silo
Enormous amount dust was present around the silo area which causes the dusty environment. The
electrical line installed in the silo has damaged line which kept in opened condition. The joint made on the wire
kept open which has not taped or insulated.
4.7 Kiln
Conveyor which installed in the kiln area has the damaged guarding which needs to be replaced. The
joint made in the guard and the conveyor has loosed and it gets off from the conveyor.
4.8 Coal Mill
The hand rails in the coal mill are in damaged condition the steps of the hand rail have to be replaced
with the new one. The damaged parts have placed over the walk path which needs to be removed immediately.
4.9 Cooler Area
The cooling area has many pipeline connection, many joints were made on the pipelines. The joint the
cooling tower line has water leakage which flows over the pipeline.
4.10 Packaging House
In packaging house lighting has done poorly. Adequate lighting needs to be done. Vibration is high in
the packing machine; dust will fly over the packing area. Required personal protective equipment must be issued
to the workers and awareness about the hazards of dust must be thought to the workers.
4.11 Coal Yard
Coal yard has placed next to the packing area. The coal has been stored in the open area in fine powder
form. The transportation of coal is done using heavy trucks. Dust is a major hazard placed on the coal yard.
V. Result and Discussion
5.1 Corrective Measures for the Minimize/Eliminate Hazards
The dust present in the lime stone and coal area are unavoidable, the workers are requested to wear the
nose mask, goggles and hard cat while working. In packing area the floors mats are recommend to reduce the
vibration produced by the machine, adequate lighting has recommended installing on the packing area. Nose
mask and hand gloves are PPE suggested while working. The safety signs and warning signs are recommended
to place on the railway track area and marking in the electrical line are needs to be done in the conveyor areas.
The spillage in the conveyor belts are avoided by changing the angle of the conveyor belts. Housekeeping must
be done weekly once in the conveyor areas to reduce the deposition of cement under the conveyor belt. The pipe
fitting in the cooler area must be checked and during maintenance time necessary changes must be made on the
cooler area. Damaged hand rails needs to be replaced with the new one. Damaged floorings also need to be
reconstructed to avoid the human falls. Adequate lighting must be done on the required areas. Floor mats can be
installed in the crusher areas to reduce the vibration effect produced by the crusher.

5.2 Suggestion And Recommendations For Avoiding Accidents In Future
Dust is one of the major hazards in the cement industry. To control the dust necessary steps had been
taken. Dust monitoring system had been installed inside the company and the output screens have been placed
on the entrance of the company. Based on the dust emission I had recommended the company to provide the
nose mask and single strap dust mask for the employees working in the packing section, crushing area and
dispatch area. Crushing and lime stone quarry area has a noise hazard. Safety helmet and nose mask had been
issued by the management for workers safety. I recommended the management to provide the ear plug to the
employee working in the crushing area and ear to the employee working in the quarry area. Conveyor belt areas
have a raw materials spillage hazard. Monthly maintenance need to be done once in a month. Modification in
the design of the conveyor belt had been recommended to avoid the spillage hazard.
VI. Conclusion
This paper has said about the safety management system in the cement industry. Recommendation had
said for the hazards present in the cement industry and also to prevent the employees from the hazards present in
the cement industry. Proper safety training for the usage of personal protective equipment had given to the
employees for safeguarding themselves from the hazards present in the working environment.
VII. Future Work
Recommendations had given to avoid hazards in the cement industry and to protect the employees from
the hazards. After the management conformation the changes need to be done to reduce or eliminate the hazards
in the plant areas.
