Reducing occupational hazards, ensuring workplace safety M S Siddiqui The latest labour force survey of the Bangladesh Bureau of Statistics (BBS) reports that 58.1 million people are employed in different occupational sectors of the country. In 2013, 87.1 per cent of workers were employed in informal sectors like agriculture. Surprisingly, most employees operate under poor working conditions and in the absence of occupational health and safety standards. Another study revealed that about 79.52 per cent of the occupational injured workers were in 40-59 age group and about 73.26 per cent of the accidents causing injury to hands, feet, torso, arms and eyes resulted in different forms of disability. All the respondents in the study suffered from occupational hazards - 75.24 per cent of total injured workers faced hand, feet, arm, eye, face and head injuries among which 27.72 per cent, 18.81 per cent, 7.92 per cent and 5.94 per cent of the total injury occurred in hands, feet, eyes and head respectively and 24.76 per cent of the injured workers suffered injury in other parts of the body. According to the International Labour Organisation (ILO), almost 11,700 workers suffer fatal accidents and a further 24,500 workers die annually from work-related diseases across all sectors in Bangladesh. The global statistic revealed that work-related diseases result in more than 2.0 million fatalities out of 2.3 million fatalities caused worldwide every year. Another 8.0 million workers suffer injuries at work often resulting in permanent disability. Additionally, workers are exposed to combinations of various potential hazards - chemical, physical, biological, ergonomic or psychological ultimately resulting in occupational diseases. Several observations indicate that a dermal exposure to hazardous agents like dusts, fumes, mists, aerosols, fibres, toxic gases, catastrophic chemicals can result in a variety of occupational diseases and disorders. It might also include Occupational Skin Diseases (OSDs) and systemic toxicity often following different mechanisms. In rapidly developing countries like Bangladesh, industrialisation brings a radical alteration with it in human lives. If industries are not appropriately designed and safety measures are not adequately adopted, adverse health consequences can ensue. Even the traditional professions like agriculture, fishing or forestry create substantial risks due to occupational and geographical setting and excessive use of chemical fertilisers. Moreover, recent studies disclosed that poisoning with metals in the industries usually takes chronic form and results from the absorption of small amounts of them stays over long periods of time. Acute poisoning may also occur from the accidental intake of large doses of toxic compounds like arsenicals. However, metals and their compounds with most physical hazards may also gain access into the body by inhalation, ingestion and in a few cases through the skin. Besides, homogenous organic solvents or chemicals produce similar hazards since other substances can dissolve without changing their chemical composition. These chemicals are used in the extraction of oils and fats in food industry, chemical industry, paints, varnishes, enamel, degreasing process, dry cleaning, printing and dying in textile and rayon industries while contributing to the occupational hazards. Such exposures may cause dizziness, peripheral neuritis, decreased vision, insomnia, headache, fatigue, unconsciousness and even death. Such poisoning works faster when the hazardous agent is absorbed through the respiratory system instead of other routes - becoming extremely disastrous for the workers long after the time of exposure to such agents. Such compounds have a risk to be absorbed mainly through the lungs via the gastrointestinal tract if taken by mouth or via the intact skin causing adverse effects. ADVERSE EFFECTS OF WORKPLACE TOXICITY: * Gastrointestinal system: Exposure to different chemicals through foods or inhalation may cause dyspepsia, anorexia, nausea and maybe secondary effect to the liver affection. Toxins and microorganisms breaching the single layer of epithelial cells have unimpeded access to the systemic circulation and hence cause such symptoms.
