LCD panels are made by various unit processes. Many chemicals are used in each process, including organic solvents, gases, acids, and metals. In the course of operating advanced facilities, X-rays, UV and electromagnetic waves are generated, and workers are likely to be exposed by these harmful factors. It was found that they use about 120 hazardous chemicals, and about 30 chemicals were measured and managed. There were no information on exposure criteria, harmfulness, carcinogenicity, reproductive toxicity and safety of the 20 chemicals. In areas where toxic chemicals are handled, local exhaust ventilation systems should be deployed to minimize worker exposure. And, a system management manual is required to prevent accidents caused by leakage of chemical materials during system abnormal operation, filling of protective fluid and inspection of pipes and so on. Ionizer used in photo process at LCD manufacturing site to prevent static electricity releases X-ray, which is ionizing radiation. Even though it is low concentration, the "radiation management zone" should be designated and operated. In case of exposure concerns, the material and thickness of the shielding shall be considered. In addition, in radiation management zones, individual dosimeters should be worn to manage exposures to workers, and radiation work precautions should be posted in places that are easy for workers to see. Most of the processes are automated so that the exposure level is significantly low. However, in the case of maintenance work, it is necessary to remove enough residues from the equipment and wear proper personal protective gear as it may be exposed to cleaning agents, residual gases, and by-products. The manufacture should analyze and evaluate materials that are not disclosed to the public for continuous management of high concentration to workers.

In the modern work environments of today, we have started putting strain on our systems as a whole- due to physical, mental and emotional demands far surpassing what our systems can bear. There is an extended list of occupational disorders that exist, nowadays, due to the upright skeletal position of the garment workers, and more so because of the uninvited pressures that they have put onto the skeletal structure as a whole. The result equals the vertebral column being unable to withstand the stresses of prolonged standing or sitting down, especially when unsupported. Back pain and musculoskeletal disorders are common occupational problems all over the world. They are a result of the previous research of author1 “Health hazards in Small and Medium Enterprises garment industries in developing countries” has been taken for this further study. The previous study was conducted in Delhi from January-2016 to June-2016. The database and result of the study with respect to Indian population has been chosen for this further study. The study revealed that Back pain and musculoskeletal problems (54%) were the commonest health problem in India. The objective of the study is to design an effective program to create an awareness surrounding the management of stress, Musculoskeletal problems as well as an effective management of pain related symptoms by using Yoga and Naturopathy Therapy

Introduction: The Industrial fire accident is a sudden and unforeseen event, attributable to any cause. Accidents are preventable, but steps must be taken to prevent them. It is a legal obligation of an organization to comply with the provisions of law, standard practises, and safety observations to avoid fire accidents. This paper investigated reasons of industrial fire accidents in Delhi, India and alternative ways to resolve them. Methods:. In study information were collected from purposively selected Five (05) major fire accidents took place in Delhi in between 2015 to 2017.The entire study is based on the accident investigation report of Directorate of Industrial Safety and Health (DISH), First Information Report (FIR) and forensic report of Delhi Forensic Science Laboratory. Result: It was found that 78% of industrial fire accidents took place in SMEs located in residential/non- industrial areas in Delhi. The cause of fire accidentwas found to be electric short circuit, improper handling and storage of flammable substances and ignorance of workers. Discussion: It was concluded from the study that unsafe electrical wiring, lack of proper training to the workers were two main reasons for increase in no. of fire accidents.It was also concluded that the industries located in industrial areas were better placed in terms of workplace compliances. The managements who were running their operations from residential/non/industrial areaswere found to be less aware on health and safety issues. Lack of enforcement by government agencies in such areas has escalated this problem. Prevention of accident: By addressing issues like carelessness, stress and fatigue, unsafe acts, design of workplace, and safety committee, adequate training to workers, managing safe & healthy workplace and sustained enforcement can reduce fire accidents in such industries.

Biological exposure indices (BEIs) are greatly useful for assessing workers’ exposure to chemicals. In biological monitoring, reference material is important to verify quality in analysis of BEIs. Therefore, we need to develop new reference materials for biological monitoring as for the need of the analysts working for biological monitoring. In this study, we developed new urine reference materials for analytical laboratories in industrial health field in Korea. We aimed to apply new materials for proficiency test to assess workers’ exposure to arsenic and phenol. Three levels of urine samples were prepared including the level of criteria of exposure of arsenic and phenol. Total arsenic samples contained arsenic metal ion, monomethylarsonic acid, dimethylarsinic acid and arsenobetaine considering the componets of arsenic compounds in real sample of workers. Phenol sample was prepared by adding phenol standard. We checked the stability of the sample kept at 4 different temperatures for 30 days, and homogeneity test for these samples using GF-AAS for total arsenic and GC-MSD for phenol. We provided these samples for proficiency test of biological monitoring in industrial health field in Korea. Total arsenic and phenol samples showed good recovery at confidence level of 95% even after 30 days at room temperature. We also verified homogeneity of all samples at confidence level of 95%. In proficiency test afterwards, 2 laboratories requested total arsenic sample and 1 laboratory requested phenol from 2016 to 2017, and proved their proficiency for analysis of total arsenic and phenol in urine. In conclusion, we confirmed the stability and homogeneity for urine reference materials of total arsenic and phenol. These samples were successfully and practically utilized as reference samples for proficiency test of laboratories working in industrial health field. As results of this study, we contributed to assess workers’ exposure to chemicals and furthermore can protect their health

Chlorpyrifos (CPF) is a commonly used organophosphate insecticide (OP). In adults, exposure to OPs has been inconsistently associated with reduced lung function. OPexposure and lung function has not been assessed in adolescents. The objective of this studywas to assess CPF exposure and lung function among Egyptian adolescents. We conducted a10-month study of male adolescent pesticide applicators (n = 38) and non-applicators ofsimilar age (n = 24). Urinary 3,5,6-trichloro-2-pyridinol (TPCy), a CPF-specific metabolite,was analyzed in specimens collected throughout the study. Spirometry was performedtwice after pesticide application: day 146, when TCPy levels were elevated and day 269, when TCPy levels were near baseline. Applicators had higher levels of TCPy (meancumulative TCPy day 146 = 33,217.6; standard deviation (SD) = 49,179.3) thannon-applicators (mean cumulative TCPy day 146 = 3290.8; SD = 3994.9). Compared with non-applicators, applicators had higher odds of reporting wheeze, odds ratio = 3.4(95% CI: 0.70; 17.41). Cumulative urinary TCPy was inversely associated with spirometricmeasurements at day 146, but not at day 269. Although generally non-significant, resultswere consistent with an inverse association between exposure to CPF and lung function.

The construction sector remains a relatively high risk segment in India. Construction workers experience a higher number of accidents and occupational disease like back pain or musculoskeletal due to falling from height and lifting of construction materials. Work related conditions that are more prevalent in construction workers include falling from height, slips, trips and falls and lifting of overweight construction materials like cement, bricks, iron rods and plates etc. Indian Construction industry employ a work force of nearly 40 million. This workforce comprises 55% unskilled labor, 27% skilled labor and rest are the technical and support stuff. As per the study1 out of 1,000 workers, 165 workers get injured during construction activities in India In every workplace we have started to put strain on our system that is way beyond what our system can bear, which is against the nature and misuse or abuse of modern technology,. The moment a worker stood up, he invited a host of problems. There is a huge list of occupational disorders that exist because worker stood up, because our body, just like an animal body, was meant to crawl around on all fours, and when we stood up, we stood up a bit faster than all the other changes could happen. And so our vertebral column is not really able to withstand the stresses of just standing or just sitting. Musculoskeletal disorders and diseases are common occupational problem all over the world. The objective of the study is to design an effective program to manage Back pain and Musculoskeletal problems of construction workers by using different postures of Yoga. Yoga and Meditation is a philosophy and practice that connects the body, breath, and mind to energize and balance the whole system in our body. This physical and mental therapy involves physical postures, breathing exercises, stimulation of mind for physical fitness, mental stability and thought and to improve overall well-being. Yoga is one of the strategies that can be used to meet the nationally established guidelines for muscle strengthening, flexibility, and balance activities in older adults. The result of our previous research “Health hazards in construction industries in India” has been taken for this further study. The study was conducted in Delhi from August-2016 to October-2017. The database and result of the study with respect to Indian population has been chosen for this further study. The study revealed that musculoskeletal problems (34%) were the commonest occupational problem among construction workers in India. The same target group has been considered for the study after intervention by yoga and meditation therapy between December 2017 to May,2018. The intermediate result shows that more than 50% construction workers suffering from MSD problem have been cured totally after the Yoga therapy. Final result is awaited.
