Abstract
Glass making industry is a very hazardous industry in which fatal and non-fatal occupational injuries occur
most frequently due to its unique nature. It is characterised by continual changes, use of many different
resources, poor working conditions, tough environments (ex-noise, direct exposure to heat, vibration, dust etc.).
The GMI is plagued by occupational risky situations and poor working conditions. Occupational health is
concerned with those factors in the work environment which can give rise to ill-health in exposed workers. The
study of Ergonomics provides the information of matching the man – machine interaction and work place
design. This study aimed to present an overview of the situation of occupational health in glass making industry
to gain information related to welfare and health facilities, health education, accident statistics, occupational
health and safety activities.
The paper is structured as follows- The first section introduces the objective of this work. The second section
represents the work methodology carried out in the Glass Making Industry. The third presents the Literature
Survey. The fourth presents an overview of the problem formulation of traditional glass making method. The
fifth section gives the Data Analysis. Finally, the sixth section presents the conclusions.
The Earnings of the glass making workers is calculated as per the jobs specified to them. In particular eight
types of jobs, usually done by glass making workers, are considered. Each job has its specific earnings. Usually
high earning jobs are very tedious to perform. Combining jobs is found to be a way of reducing OHH and yet
maintaining the good earnings. One severe job (firing-work) is combined with the rest of three jobs sequentially
resulting in three job combinations Workers performing such jobs suffer from severe stresses and other health
problems. NSGA-II is used to search for those solution points which would simultaneously minimize the
occupational health hazards and maximize the earnings.

1. Introduction
Ergonomic design and comfort of handling objects and operating of equipment are often linked to the activity of
the human body, expressed in muscle action, depending on the arrangement and interaction of man and machine.
Ergonomics design and comfort of handling objects and operating of equipment are often linked to the activity of
the human body, expressed in muscle action, depending on the arrangement and interaction of man and machine
.Muscles plays a major role when mechanical factors are involved. Psychological fatigue also plays an important
role in the actions of daily life and work.
Working in glass industries may leads towards many occupational health hazards. Managing such hazards in an
optimum manner for workers of OKAY Glass Industries is a challenging job. These workers are subjected to
high heat stress owing to high temperature of the furnace. The worker aims at maximizing his earnings and job
growth by subjecting themselves to extreme work conditions.
Factors like long working hours, improper rest breaks etc. Severely affect worker’s health and depending upon
the type of job, they suffer from various disorders when working beyond prescribed limits.
The molten mixture prepared with the above method is glass. Molten glass is then taken out from the furnace
with the help of iron pipes. The glass worker then blows air through their mouth from the other end of pipe and
the molten glass, which is on the second end of the pipe, blows like balloon. Before this blown glass cools, it is
quickly placed in the dyes of desired size and shape. In the glassware industry the temp goes up to 30000C.
High temperature and harmful vapours in glassware manufacturing causes health disorders to workers, such as
Heat Stroke, T.B., Dehydration, Heat crams, Heat rashes, Fainting, Heat Exhaustion etc.
