OCTOBER 19-20, 2012 - YMCA University of Science & Technology

Proceedings of the National Conference on
Trends and Advances in Mechanical Engineering,
YMCA University of Science & Technology, Faridabad, Haryana, Oct 19-20, 2012
2. Work Methodology
2.1. Visit the glass making industry to explore the real life scenario of glass making workers.
2.2. Questionnaire development-
A questionnaire was developed comprising check-box questions and open-ended questions.
The questionnaire was divided into four sections that covered: information about the Health Risk
(b) Occupation History, (c) Health Risk questions for employer side and (d) Health Risk questions at
the working conditions.
2.2.1 Sample:
The targeted employees were 10-12, producing various glass-ware products.
2.2.2 Taking feedback from the workers of ‘OKAY GLASS INDUSTRIES’ through questionnaire regarding
their:
2.2.2.1 Heat exposure limits
2.2.2.2 Health disorders they are suffering from
2.2.2.3 Anthropological data of workers
2.3. Analysing the perceived discomforts of ‘OKAY GLASS INDUSTRIES’ with respect to variation in the
following factors on the site itself:
2.3.1 Rest break
2.3.2 Working hours
2.3.3 Working hour between two consecutive rest breaks
2.3.4 Switching the job with in same industry so as to reduce OHH
2.4. Data Analysis:
Data from the questionnaire were coded and analysis.
2.5. Finding the range of optimal parameters using some optimization techniques so as to minimize health
disorders and maximize earnings of firers.
3. Literature Survey
According to human psychological nature study a person start giving low performance in his duty assigned if
conditions are not favourable with his body requirement in both physically and mentally. Ruchi et al. (2012)
stated the combined study of HEERAP with its implementation which helps in giving proper working
atmosphere in which a worker can do his best without any fear or fatigue in mental and physical type [1]. Ajit et
al. (2012) investigated the extent to which OHH can be minimized in glass making industry [2]. Adel et al.
(2011) examined the extent to which OHS risks are taken into account in the project management and industrial
safety practices with special focus on the construction industry [3]. Iman et al. (2011) investigated the effects of
wearing typical industrial gloves on hand performance capabilities & subjective assessments for an extended
duration of performing a common assembly task, wire tying with pliers, which requires a combination of
manipulation & force exertion. Results showed that wearing gloves significantly increased the muscle activity,
wrist deviation & discomfort whilst reducing hand grip strength, forearm torque strength & touch sensitivity.
Combined results also showed that the length of time for which gloves are worn does affect hand performance
capabilities & that gloves need to be evaluated in a realistic working context [4]. Qiang et al. Proposes a Genetic
Algorithm approach to assessing work zone casualty risk defined as the likelihood of a vehicle occupant being
killed or injured in a work zone crash and demonstrates that the GA approach is a good alternative for the work
zone casualty risk assessment [6]. Magne et al. (2011) study stated that the pain levels in different body areas
were significantly correlated with subjective assessment of reduced work capacity in small offices and in the
office landscape. Moving into an office landscape might be problematic due to high luminance from the
windows giving glare & increased contrast reduction in the work area [7]. N.Louis et al. (2009) study indicates
that upper limb muscles forces augment with distance [9]. Y.Lan.Noy et al. (2009) study will inspire & motivate
new research efforts that will lead to dramatic reduction in loss & human suffering [10]. A.M.Makin et al. (2008)
study utilising a systematic approach to safety, OHS MS optimise the overall co-ordination of prevention &
control measures [13]. Sanjay et al. (2008) done a analysis to reduce OHH of brick kiln workers [12].Hal
W.Hendric (2008) study stated that how to achieve the potential of ergonomics for practical engineering design
use .Ergonomics professional education programs will need to be continuously updated to provide the necessary
knowledge, methods & skills to meet those challenges[11]. Dahlberg et al. (2004) compared the work technique
and self-reported musculoskeletal symptoms between men and women performing the same type of work tasks
within a metal industry [16]. Lipscomb et al. (2004) studied musculoskeletal symptoms among commercial
fishers in North Carolina.Salvendy, G (2006) investigated the extent to which process, barriers and outcomes are
accommodated by current ergonomics consultancy practices [15]. Hyung-Yun Choi (2001) presents a short
overview on the emerging ESI Group comfort and ergonomics models of the human body, that are developed to
study the activation levels of the skeletal muscles, needed to sustain various load conditions[17].
