Introduction
1/4/20164
Ppe is ‘’specialized clothing or equipment worn by
an employee for protection against infectious
materials” (OSHA)
These injuries and illnesses may result from contact
with chemical, radiological, physical, electrical,
mechanical, or other workplace hazards.
Personal protective equipment may include items
such as gloves, safety glasses and shoes,
earplugs or muffs, hard hats, respirators, or
coveralls, vests and full body suits.
5. Statement of the problem
1/4/20165
When studying the various accidents as well as
claims & their causes; it is observed that there is
a large percentage attributable to personal
injuries, most of which are because the crew
members did not use the Personal Protective
Equipment properly.
In most cases it is documented that the PPE were
used but still we encounter too many accidents.
This problems occurs mostly due to lack of
knowledge
how, when and where to use these ppe’s
6. Significance of the study
1/4/20166
Making the workplace safe includes providing
instructions, procedures, training and supervision
to encourage people to work safely and
responsibly
Even where engineering controls and safe
systems of work have been applied, some
hazards might remain. These include injuries to:
the lungs, e.g. from breathing in contaminated air
the head and feet, e.g. from falling materials
the eyes, e.g. from flying particles or splashes of
corrosive liquids
7. 1/4/20167
the skin, e.g. from contact with corrosive
materials
the body, e.g. from extremes of heat or cold and
they are being affected by these problems in this
time.
PPE is needed in these cases to reduce the risk.
Because of this emphasis must be given on the
knowledge of the utilization of ppe
8. Objectives
1/4/20168
The broad objective of the study is to assess the
current practices and challenges of ppe utilization
in UOG construction site and it s impact on the
health of the workers.
The specific objectives of the study are assessing:-
Asses the knowledge of workers on ppe
utilization
Key health and safety risks associated with PPE.
The behavior of works in using PPE in work place

RELATED LITERATURE REVIEW
1/4/20169
Construction safety
Construction is the most dangerous land-
based work sector in Europe, after the fishing
industry. In the European Union, the fatal
accident rate is nearly 13 workers per 100,000
as against 5 per 100,000 for the all sector
average.
The problem is not that the hazards and risks are
unknown, it is that they are very difficult to control
in a constantly changing work environment.
10. 1/4/201610
Different occupational hazards mainly found in
the construction areas like
Noise
Chemical Hazards
Psychosocial Hazards
Ergonomic Hazards

Methods and materials
1/4/201611
Design of the Study
A descriptive survey design will be used so as to
assess the current practices and challenges of
ppe utilization of selected construction sites.
Descriptive survey design becomes useful
particularly where one needs to understand some
particular information
From these descriptive study designs we are
going to use cross sectional study design
because of it s
Simplest easily performed
Fast takes up little time to conduct
Relatively cheap
12. Data Sources
1/4/201612
Primary data sources
workers
managerial body's
safety officers if present
Secondary data sources
different documents
different literatures
13. Sampling Technique
1/4/201613
A simple random sampling technique that
considered a fair representation of all workers in
the construction area they employed. The reason
we are going to use SRS are
Relatively easy to randomize and Its unbiased
The population is little
accuracy of representation
We use lottery method to chose.
14. Sample Population and Sampling
Technique
1/4/201614
Workers are selected from four working sites
which is found in the CMHS campus since a
complete survey cannot be undertaken. The
sample size for the four working sites was
determined using the mathematical approach by
Miller and Brewer (2003):
n=N/ [1+N (α) ²]
Where
n-is the Sample size,
N-is the Sampling frame,
a - is the Error margin and 1-is the Constant
15. Instruments of Data Collection
1/4/201615
Questionnaire,
An interview,
Checklist and
Document analysis will be the main data
gathering instruments.
16. Reliability of Research
Instrument
1/4/201616
reliability is the degree of consistency with which
an instrument measures the attribute it is
designed to measure
The questionnaires that will administered to
workers in the various categories were consistent
and follow a logical pattern such that responses
not contradict or conflict each other.
In addition, biases in data collection will be
reduced by ensuring the knowledge of researcher
or student.
17. Validity of Research
Instrument
1/4/201617
The validity of a research instrument determines
whether the research truly measures that which it
intends to measure.
Questions were based on information gathered
during the literature review to ensure
representativeness and
they are also based on the objectives and the
data requirement.
18. Ethical Considerations
1/4/201618
Research requires not only expertise and
diligence but also honesty and integrity.
This helps to protect the rights of respondents To
render this, the
Permission will be obtained from the leaders of
the various offices as well as individual
respondents.
Respondents will be well communicated about
the purpose of the study, the required data and
assured that there would be no potential risks or
costs associated with the exercise.
19. Data Analysis
1/4/201619
The data collected from the respondents will be
analyzed
quantitatively and
qualitatively.

22. ACKNOWLEDGEMENT
1/4/201622
Firstly, we would like to thank our instructor doctor taddese for
giving us this assignment to improve our knowledge on
research methodology through technical or practical
assignments.
We wish also render my profound and heartfelt gratitude to
our advisor Mr. Ararso (mph). I am exceedingly grateful to him
for his responsible and constructive suggestions, valuable
contributions and constructive criticisms for making this work
what is today.
