Now a days, Industrial safety has become a huge concern in industries of Pakistan. Ergonomics can be defined simply as the study of work Ergonomics, designing the job to fit the worker, rather than physically forcing the worker’s body to fit the job. Its objective is to improve the human well-being and optimize overall system’s performance. Ergonomics is not a new science, although the term has become more common lately. The phrase was first coined in 1857
The main focus of ergonomics is the ‘worker’, whether the situation is designing of work-place or issues relevant to everyday life. Ergonomics keeps an eye on the physical and psychological capabilities as well as the limitations of humans to evade unsafe, unhealthy or uncomfortable situations at the work place This helps to ensure a harmonious relationship between employer and employee, resulting in the enhancement of productivity and efficiency 
knowledge from different scientific disciplines including physiology, biomechanics, psychology, anthropometry, industrial hygiene and kinesiology [6, 7] The art of fitting the task, work station, tools and equipment according to the physical abilities of a worker helps the employer to reduce the physical stress and the work related disorders known as musculoskeletal disorders (MSDs) MSDs include injuries to soft tissues, tendons, ligaments and nervous system. It affects bones, muscles and tissues which form the body joints , especially the arm and the back . MSDs are also referred interchangeably as CTDs, repeated trauma, Repetitive Stress Injuries (RSIs) and occupational overexertion syndrome [10, 11].
Mostly, MSDs affect the upper limb (arm, shoulder, elbow, wrist and hand), neck and the back that become worse by prolonged working . The problems caused by MSDs are pain, numbness, tingling, stiff joints, difficulty in moving, muscle loss, paralysis and disorders that include Carpel Tunnel Syndrome (CTS), Tendinitis, Sciatica, Herniated disk and back pain . Two common MSDs in the work place are Carpel Tunnel Syndrome (CTS) and back injury. Repetitive motion and high force are responsible for the CTS , which affect the wrist and hand by compressing the median nerve which passes through the carpel tunnel in the wrist 
Sagittal plane (divide the body into right and left halves), Coronal plane (divides the body into front and back portion) and Transverse plane (divide the body into upper and lower parts)
Rapid Upper Limb Assessment (RULA) On the work place, problems arise due to awkward postures, force and the nature of task and thus provide a reason for more exposed body parts than only wrist and hand. For this situation RULA may be employed, as it is a job analysis tool used to analyze the body segments such as Wrist, Forearms, Elbows, Shoulders and Neck. Like SI, RULA assessment provides a number (score) which provides the information to the analyst about the disorders only in the upper limb [6, 17]. Rapid Entire Body Assessment (REBA) Job analysis tool used to analyze the entire body. REBA assessment provides a number (score) after measuring respective parameters, provides the information to the analyst about the worker’s whole body condition, risk level and suggests how the action may be taken .
This paper presents the conditions of an automobile industry that is involved in manufacturing various parts for two wheelers. Basically, the firm is an OEM (Original Equipment Manufacturer) vender for famous companies of auto-bikes in Pakistan. This industry has three facilities: press part unit, manufacturing/assembling unit and electro plating unit. Most of the products are manufactured in the manufacturing/assembling unit, and at the end, all the products are sent to plating unit for electroplating. There are altogether 200 workers excluding the management staff. For this study we have focused only on the Manufacturing Unit of this industry, where we studied the workers individually, interviewed them, recorded videos and took photos of their working postures. In the manufacturing unit many jobs were found having high severity risk factors, but to our astonishment none of the injuries has ever been reported to top management and only minor accidental records were found. In case, a worker feels discomfort, the worker is suggested to take some days off and if something serious happens, apart from some worker most have no right to claim any compensation because most of the workers are on daily wages and thus don’t have any legal contract with the company.
There are various tools available for job analysis as presented in the previous section; we have selected Strain Index (SI) technique as a first step in job analysis to exclusively focus on wrist and hand postures. Table 4 shows the selected photos of different jobs performed at the manufacturing unit. After a critical analysis of the recorded videos and the gathered data, Strain Indices were calculated and as an example the calculation for posture 1 is presented next.
Moore and Garg  have provided the tables for “rating criteria” and “multiplier”, which are used here to evaluate the SI for posture 1. First, the rating criteria (table-I in ) are selected for each multiplier along with the value of the corresponding multiplier (table-II in ). Table 1 has already provided a description of the six multipliers and the SI calculation using (1) for posture 1 is presented below (similarly the Strain Indices for all nine postures are shown in the table 5): Intensity of effort rating 2, multiplier of 3 Percentage duration of exertion rating 3, multiplier of 1.5 Effort per minute rating 2, multiplier of 1.0 Wrist Posture rating 3, multiplier of 1.5 Speed of work rating 4, multiplier of 1.0 rating 3, multiplier of 0.75 SI = 3 × 1.5 × 1.0 × 1.5 × 1.0 × 0.75 SI= 5.1 (means worker is at some risk and caution is needed to save the worker)
Proposed ergonomics awareness program consists of the following four phases on the lines of OSHA , though the underlying details are extended keeping the Pakistani industrial context in mind: Phase 01: Analysis of work place Phase 02: Prevention and control of Hazards Phase 03: Personnel training and education Phase 04: Medical Management
This paper highlighted the facts related to ergonomics in a manufacturing unit of a Pakistani automobile industry. In this facility workers are working in a poor environment with awkward postures of hand and wrist. The data collected at this facility, through signs and symptom survey forms, reveal that more than 50% problems lie in the upper extremity of a worker’s body. Strain Index (SI) was used to analyze this upper extremity (only hand and wrist). An ergonomics awareness program was proposed to enhance the workers’ knowledge and capability by improved learning about injury-prone jobs and postures involving the use of wrist and hand. In another paper we will provide the extensive analysis on those jobs in which whole body is involved using the postural analysis tools like Rapid Upper limb Assessment (RULA) and Rapid Entire Body Assessment (REBA). This paper proposes an ergonomics awareness program, if employed in its true spirit will surely increase workers’ morale, and will help enhance the communication and cooperation between the management and their employees for higher productivity and profitability.
