Occupational hazards refer to any factors in the work environment that have the potential to cause harm or injury to workers. These hazards can arise from physical, chemical, biological, ergonomic, or psychosocial sources. Workers in various industries are exposed to different hazards, and these exposures may lead to short-term or long-term health problems. The goal of Occupational Health and Safety (OHS) is to protect the workers from these risks by implementing preventive measures, maintaining safe work practices, and ensuring compliance with safety regulations. Biological hazards are one of the most significant categories of occupational hazards, especially in industries such as healthcare, agriculture, food processing, and research. Biological hazards include exposure to bacteria, viruses, fungi, parasites, and other microorganisms that can cause diseases. These hazards are particularly concerning because they are not always immediately visible and can be transmitted through air, water, direct contact, or vector organisms such as insects. One of the most well-known biological hazards is exposure to infectious diseases, which can be contracted through direct contact with infected individuals, animals, or contaminated surfaces. For example, healthcare workers are at high risk of contracting diseases such as tuberculosis, HIV/AIDS, and hepatitis B and C through needle sticks, bodily fluid exposure, or airborne pathogens. Similarly, workers in agriculture, particularly those handling animals or animal products, are susceptible to zoonotic diseases like avian influenza, brucellosis, and Lyme disease.
