INTRODUCTION
The concept of ergonomics in workplace design is ignored
in most of the industries. This problem is very much
prevalent around the world, including India. The problem
of workplace design should be thought of at the blueprint
stage involving an ergonomist along with process
engineers, and production engineers. The workplace
design is basically governed by the two main dimensions,
i.e., clearance and reach, where clearance will be focused
on taller individuals and reach for shorter. Lacing of which
force the workmen to assume awkward posture, poor
posture, and bad posture. Assuming those posture by the
workmen are either due to inadequate workspace or due to
lack of awareness of the workmen. In most of the
unorganized sectors in India, the workers are forced to
work in low wage where their work effort is maximum but
occupational safety is highly neglected.

ABSTRACT
Background: Small scale establishments often neglect the worker safety and comfort which impacts both productivity
and workers’ safety. Various studies have been conducted in such small -scale establishments but not much has been
done on aluminium utensil manufacturing factories. Spinning and casting are two important processes for
manufacturing of aluminium utensils. But not much has been studied to assess the hazards of the involved workers. The
present study is an attempt to explore this previously unnoticed area.
Methods: The study was conducted in different small scale aluminium utensil factories in West Bengal. Sixteen
spinners and seventeen casting workers were evaluated for this study. The analysis of posture was done by rapid upper
limb assessment (RULA), rapid entire body assessment (REBA) and Ovako working posture analysis system (OWAS).
The body parts discomfort was assessed by using Cornell musculoskeletal discomfort questionnaire and Nordic
questionnaire was also used to assess the pain they experience.
Results: All the casting workers are experiencing postural load beyond the recommended limit whereas in case of
spinner, five workers experienced less postural load due to favorable work conditions. Casting workers mainly suffered
from low back, neck, right shoulder pain whereas spinners suffered from wrist and finger pain followed by lower
extremity pain.
Conclusions: Both group of workers are experiencing postural load and discomfort. In case of casting workers, the
prevalence was high and immediate interventions are needed. The discomfort is particularly high during the end of
shifts.
