Chemical hazards refer to the potential risks associated with exposure to hazardous chemicals and materials, which can cause acute or long-term adverse health effects. These hazards are typically classified separately from biological hazards and can include various types such as asphyxiants, corrosives, irritants, sensitizers, carcinogens, mutagens, teratogens, reactants, and flammables. Exposure to chemical hazards in the workplace is a type of occupational hazard, and long-term exposure to certain chemicals has been shown to increase the risk of heart disease, stroke, and high blood pressure. Examples of chemical hazards include corrosive substances, toxic chemicals, flammable materials, explosive compounds, and reactive substances. Chemical hazards can result from exposure to various forms of chemicals, including medications, solutions, gases, vapors, aerosols, and particulate matter, which can be potentially toxic or irritating to the body system. It is important to ensure the safe handling and controlling of hazardous chemicals in the workplace to mitigate the associated risks. Chemical hazards can cause a wide range of health effects, from localised (skin irritation or burns) to systemic effects such as occupational cancers and lung disease. Overall, chemical hazards pose significant risks to both human health and the environment and require careful management and control to ensure safety in the workplace.
