INTRODUCTION
1.1 INTRODUCTION TO THE STUDY
Industrial health and safety today mean protecting the life and health of people
from the dangers arising during or through work. Industrial health and safety are one of
the social components of industrialization and technicalization. They are supported to
humanize not only technology and chemicals but also the whole working situation. The
Status of industrial health and safety in a country is therefore determined to a large
extent by the degree of industrialization and technicalization. The status is a good
indicator for the social, political, democratic and cultural standard of the state or society.
Health and safety is a discipline with a broad scope involving many specialized
Fields. In its broadcast sense, it should aim at:
• The promotion and maintenance of the highest degree of physical, mental and
Social well-being of workers in all occupations.
• The promotion among workers of adverse affects on health caused by their
working conditions.• The protection of workers in their employment from risks resulting from factors
adverse to health.
• The placing and maintenance of workers in an occupational environment adapted
to physical and mental needs.
• The adaptation of work to humans.
In other words, industrial health and safety encompasses the social, mental and
physical well-being of worker, which is the “whole person”. Successful health
and safety practice requires the collaboration and participation of both employers
and workers in health and safety programmes, and involves the consideration of
issues relating to occupational medicine, industrial hygiene, toxicology,
education, Engineering safety, ergonomics, psychology, etc.,

1.2 INDUSTRY PROFILE
1.2.1 An Overview of Indian Pump Industry
Pumps play a dominant role in the sectors like agriculture, production of oil and
natural gas, petroleum refining, petrochemicals, power generation, domestic and
household utilities, etc, and contribute a major part in nation’s economy.
Pump is not a new concept in the Indian industry. In fact, the ‘Pichkari’ which Lord
Krishna and his playmates used for splashing coloured water on Gopies, can be termed as
the oldest reference to a pump concept, especially of the reciprocating plunger type.
Thus, pumps must be an Indian invention, but commercial production of pumps in India,
as contemporarily understood, is quoted to be way back in the first decade of twentieth
century.
Manufacturing Scenario
Presently, the gross value of pump’s production in India is estimated to be in the
order of US$ 450 million(approx. 1.2 million No.).The scales of production and corporate
structures of manufacturers range from the small scale industries, medium to large scale
industries, both in the unorganised sectors and also public sector units.
In terms of drive ratings, the range of manufacture extends from fractional horsepower
designs to large pumps of drive rating of the order of three MW. Almost all types of
pumps, manufactured internationally, are also made in India.
Demand and Supply Situation
Indian pumps have contributed to the nation’s economy significantly. Prominent
sectors amongst them are agriculture, onshore and offshore production of oil and natural
gas, petroleum refining, petrochemicals, mining, ship-building and marine duties, power
generation, public water supply and sanitation, domestic and household utilities, process
industries producing fertilizers, insecticides, pesticides, drugs and pharmaceuticals,
textiles, soaps and detergents, cosmetic and health care products, dairies, vegetable oil
and processed and packed food products, breweries, paints, etc.

National and International Standards in Practice
Indian standards on agricultural pumps have been trail-blazing even in the
international context, with respect to minimum efficiency norms which were incorporated
in the standards, since 1979, and they have been reviewed and upgraded periodically.
Comparatively, only the 1994 edition of hydraulic Institute Standards gives a monogram
on estimating efficiency of centrifugal pumps. These are again, not mandatory, because
there is no certification marking system in practice for compliance with the HIS-
monogram efficiencies.
Many companies in the organized sector and some, even in the medium-scale sector,
have attained ISO-9000 certification.
Amongst process pumps, the dimensions and ratings often follow the ISO-2858
specifications, whereas API-610’s technical requirements like centre-line supports for
high temperature applications, vibrations levels, nozzle loads and moments, are also
widely popular.
In the associated field of mechanical seals, Sealol, Durametallic, Mars Cyclam,
Burgmann makes have been manufacturing for quite some time and Flexibox and John
Crane are also known to be actively interested to chip in. Alongside, magdrive and
canned motor pumps have been successfully developed indigenously.
Exports and Share in the Global Market
Exports have been a regular feature of Indian pump industry for years. Indian
pumps have reached more than sixty countries around the world including developed
countries.
Some buy-back arrangements have also consistently been in operation for nearly twenty
in some cases, showing the strong confidence and trust, earned in the process.
But, by and large, the size and potential of the domestic market has itself been so good
that majority of manufacturers take little interest in exports to the global market is
admittedly insignificant. In contrast, the size of domestic markets of most individual
European countries has been so small that perforce of such situation. European
manufactures have developed a culture of being a global player, right from the launch of
an enterprise.

Reservations or Constraints?
It is not easy to explain why manufacturing technologies, like on-line welded
sheet metal fabrication do not have an appeal for real large-scale production as the truly
appropriate technology. Such a venture is bound to be very capital-intensive and Indian
enterprises are typically shy of big
Investments. Alongside, there are natural apprehensions of being able to garner a market
position, which would give an assured and sustainable returns on such large-scale
investments. Yet conveyorised assembly lines have been there, especially, in the
production of agricultural pumps, CNC machines have also been in vogue for long. So,
Indian psyche is shy but definitely open-minded, often needing only an attitude
adaptation.
1.2.2 Future of the Industry
The resilience exhibited by the Indian economy, in the midst of the turmoil in
South Eastern economics and politically motivated economic sanctions, has underscored
the basic growth-prospective characteristics of the Indian economy. That should be a
strong enough base to reason that except for the place of the growth rate, growth by itself
will be always there. Since pumps are needed in every sector of the economy, the Indian
pump industry will always grow.

HEALTH AND SAFETY ISSUES IN TEXTILE INDUSTRY
The major Health and safety issues can be stated as under:
1. Exposure to cotton dust.
2. Exposure to chemicals
3. Exposure to noise
4. Ergonomic issues
1. Exposure to cotton dust
The workers engaged in the processing and spinning to cotton are exposed to
significant amounts of cotton dust. Exposure to cotton dust and other particulars leads to
respiratory disorders including tightening of the chest, coughing, wheezing and shortness
of breadth among textile workers.
In the year 1938 in USA, it was estimated that the disease had already affected
about 35000 people, while 100000 other people were at risk of contracting it. Hence the
Occupational safety and Health Administration i.e. OSHA made it compulsory for
employers in the textile industry to protect their workers from over exposure to cotton
dust and its evil effects.
As per those guidelines, the employer is required to inform the employees in
writing of the dust level present in the atmosphere as well as the steps that the
management is planning to take for its reduction. If the dust level cannot be reduced, it is
the duty of the management to provide respirators to the employees. The OSHA cotton
dust standard was amended in the year 2000.
A study conducted by R. Steinberg, J. Hannak and K.Balakrishnan regarding textile units
in India revealed that pulmonary function in textile workers decreased significantly with
8/7/2019 Chapters i,II,III
http://slidepdf.com/reader/full/chapters-iiiiii 14/51
14
exposure to cotton dust over a long period of time. Another study conducted on textile
units in Mumbai, India indicated as 11-33% incidence of chronic Bronchitis in textile
workers.
2. Exposure to chemicals
Workers in the textile industry are also exposed to a number of chemicals,
especially those engaged in the activities of dyeing, printing and finishing. Contact of the
chemicals with skin as well as inhalation of the chemicals can lead to several serious
health effects.
3. Exposure to noise
High levels of noise have been observed in most of textile industries, particularly
those in developing countries. In the long run, exposure to high noise levels has been
known to damage the eardrum and cause hearing loss. Other problems like fatigue,
absenteeism, anxiety, reduction in efficiency, changes in pulse rate and blood pressure as
well as sleep disorders have also been noted. Lack of efficient maintenance of machinery
is one of the major reasons behind the noise pollution in a majority of the units.
A study of 77 employees in textile mills in Nagpur was conducted by Ruikar MM,
Motghare DD and Vasudeo ND. This study revealed that 76.6% of the employees were at
risk for developing noise-induced hearing loss. The study of Indian textile units by
R. Steinberg, J. Hannak and K. Balakrishnan indicated that 21.3% of the workers studied
suffered from noise-induced hearing loss.
4. Ergonomic Issues
8/7/2019 Chapters i,II,III
http://slidepdf.com/reader/full/chapters-iiiiii 15/51
15
Ergonomic issues are observed in majority of the textile units in India. Most of
these units have a working environment that is unsafe and unhealthy for the workers.
Workers in these units face a number of problems such as unsuitable furniture, improper
Ventilation and lighting, and lack of efficient safety measures in case of emergencies.
The workers in such units are at risk for developing various occupational diseases like
lower back pain, neck pain, shoulder pain, and osteoarthritis of the knees.
As per a study by parimalam, Kamalamma N. and Ganguli AK in the year 2006,
there is a considerable difference in the heights of the stools and the tables used for
various operations. This led to the workers having to sit in as uncomfortable position for
entire work days. The stools were not padded and did not have backrest in most of the
units, leading to increased discomfort on the part of the workers. Also, the level of
lighting was low and improper placement of lighting fixtures led to low lighting at the
point of work, leading to eyestrain.
Apart from this, lack of efficient measures for the safety of the workers was also
observed. Lack of essential items such as first aid kits, fire extinguishers, and alarms was
noted in most of the units. This puts the workers under great risk in times of an
emergency. Protective equipments like metallic gloves were not provided to the workers
in several units for protection against potential accidents and injuries. Thus safety and
health measures play an important role in any industry. It is essential that the workers be
aware of the various occupational hazards in the industry. At the same time, it is
necessary that the management take the necessary steps to protect workers from potential
hazardous situations.
MEASURING THE IMPACT OF PSYCHOLOGICAL CONTRACT FOR
HEALTH AND SAFETY
8/7/2019 Chapters i,II,III
http://slidepdf.com/reader/full/chapters-iiiiii 16/51
16
Safe behavior at work is a managerial challenge. Traditionally, research into
occupational health and safety has focused on safety culture and safety climate to explain
risk-taking and safety behaviors. Managers in high-hazard industries have therefore
concentrated on creating positive safety cultures and climates.
Recently, 1 proposed that a “Psychological contract for health and safety” may
offer an alternative explanation for individual risk-taking and safety behaviors at work.
The psychological contract is used to explain general areas of the employment
relationship and has been investigated by examining the fulfillment of promises or
obligations from both employees and employers’ perspectives. It should be noted that
different occupational groups (if not different individuals in the same group) may have
their own perceived obligations about health and safety. Therefore, organizational and
occupational contexts need to be considered carefully.
A study was conducted to develop a psychological contract measure for health
and safety. It aimed to discover whether employees with a positive psychological contract
would trust line managers more with respect to health and safety, would perceive a better
safety climate (i.e., would have more positive perceptions about what their line managers
say and do about health and safety).
The results showed participants had high expectations of what their employer had
promised with respect to health and safety. Most notably training about the risks in their
jobs, personal protective equipment and an incident reporting system. On average,
perceived obligations or promises were seen to be slightly unfulfilled, especially with
regard to investigating accidents.
The main finding was that there were significant positive relationships between
the psychological contract, trust and safety climate measures. This suggests that line
managers play a key role. To ensure that employees develop appropriate expectations,
line managers should be involved in the development of organizational health and safety
policies and procedures so they will be better able to live up to their expectations.
THE MAIN THEME OF THE PROJECT
8/7/2019 Chapters i,II,III
http://slidepdf.com/reader/full/chapters-iiiiii 17/51
17
2.1 NEED FOR THE STUDY
The project work entitled “A Study on Workers’ attitude towards health and
safety measures” in Sam Turbo Industry Ltd.,Coimbatore, was undertaken with a view to
have a descriptive study of health and safety conditions prevailing in the firm.
The selection of the topic has its own importance in the present industrial
scenario. The concept of health and safety has gained importance right from the onset and
has been in transition since it began that most of the industrial accidents can be avoided
with a bit of care and better planning.
Work plays a central role in people’s lives, since most workers spend at least
eight hours a day in the workplace, whether it is on a plantation, in an office, factory, etc.,
Therefore, work environments should be safe and healthy. Yet this is not the case for
many workers. Every day workers all over the world are faced with a multitude of health
hazards, such as:
• Dusts
•
Gases
• Noise
• Vibration
• Extreme temperature
Unfortunately some employers assume little responsibility for the protection of
worker’s health and safety. In fact, some employers do not even know that they have the
moral and legal responsibility to protect workers. As a result of the hazards and a lack of attention given to health and safety, work related accidents and diseases are common in
all parts of the world.
According to Factories Act, 1948

2.5 RESEARCH METHODOLOGY
Research Methodology is a way to systematically solve the research problem. It
may be understood as a science of studying how the research has to be done
scientifically. From this we analyze and study the various steps that ate generally adopted
by the research and study the research problem along with the logic behind them.
RESEARCH
Research is common parlance refers to search for knowledge. One can also define
research as a scientific and systematic search for pertinent information on a specific topic.
RESEARCH DESIGN
Research Design is a framework or plan for a study that guides the collection and
analysis of the data. A research design is the arrangement of conditions for collection and
analysis of data in a manner that aims to combine relevance to the research purpose with
economy in procedure.
The research design can be broadly classified into 3 categories namely
exploratory, descriptive and experimental. The design used in the study was Descriptive
research design.
POPULATION
The entire group of people, events or things that the researcher desires to
investigate. Total number of employees in the production department of the organization
constitutes the population.
8/7/2019 Chapters i,II,III
http://slidepdf.com/reader/full/chapters-iiiiii 25/51
25
SAMPLE SIZE
A subset from which data are collected and used to estimate parameters of the
total population. Here the sample size is 100.
SAMPLING TECHNIQUE
The sampling technique used was Simple Random Sampling. It is a probability
sample in which each population element has a known and equal chance of being
included in the sample and in which every combination of n population elements is a
sample possibility and it’s just as likely to occur as any other combination of n units.
DATA COLLECTION
For this study the data was collected by means of primary sources and secondary
sources.
METHODS OF DATA COLLECTION
The primary data was collected through questionnaire and the secondary data was
collected through books, journals, websites and company brochure.
STATISTICAL TOOLS USED
The statistical tools used were Percentage Analysis and Chi-Square Analysis
8/7/2019 Chapters i,II,III
http://slidepdf.com/reader/full/chapters-iiiiii 26/51
26
PERCENTAGE ANALYSIS
Percentage refers to a special kind to a special kind of ratio. Percentage is used in
comparison between two or more series of data. It is used to describe relationships, to
compare relative terms and distribution of two or more series of data.
Percentage of respondents = Sample / Total respondents * 100.
CHI- SQUARE ANALYSIS
The most widely used non-parametric test of significance is the
Chi-Square test. It is particularly useful in tests involving nominal data but can be used

3.1 SUGGESTIONS
Based on the study “Workers’ attitude towards health and safety Measures at Sam Turbo
Industry Ltd., it is understood that the company is providing good health and safety
measures and the required precautions.
8/7/2019 Chapters i,II,III
http://slidepdf.com/reader/full/chapters-iiiiii 47/51
47
However the awareness about safety measures is less among the helper category of
employees. Hence the organization should take care and ensure that proper training and
awareness is provided to them.
The study also indicated a few areas where improvements can be made and some
corrective measures can provide much more satisfaction to the employees.
The following recommendations made are purely the opinion of the workers and they
are:
To provide good and clean drinking water facility
To maintain clean toilets
To bring in more mechanization of work to ease the work of production so that idle time
of the workers can be reduced.
To increase the space of work area.
3.2 CONCLUSION
From the present study, it is concluded that most of the employees are aware of
the health and safety measures of the firm. Also the employees have an overall positive
attitude on health and safety measures provided by the firm and the study provides a
8/7/2019 Chapters i,II,III

suggestion that the attitude of the employees can be increased by improving some of the
measures as mentioned in the suggestions above.
