Early detection of occupational diseases is a crucial component of occupational health and safety management. Occupational diseases develop gradually due to prolonged exposure to hazardous agents such as chemicals, dust, noise, vibration, biological agents, or ergonomic stressors in the workplace. Timely identification of early symptoms helps prevent permanent disability, reduces compensation costs, improves worker productivity, and promotes a safe working environment. The steps for early detection of occupational diseases are as follows: identification of workplace hazards, baseline health assessment before employment, periodic medical examinations, health surveillance programs, biological monitoring, environmental monitoring, maintenance of health records, training and awareness among workers, prompt reporting and referral system, and review and evaluation of occupational health data. The first step is identification of workplace hazards. This involves systematic assessment of all physical, chemical, biological, and ergonomic risks present in the work environment. Hazard identification may be carried out through workplace inspections, job safety analysis, safety audits, and consultation with workers. Understanding the nature of exposure helps in predicting potential occupational diseases such as silicosis in mining, asbestosis in construction, dermatitis in chemical industries, or noise-induced hearing loss in manufacturing plants. The second step is conducting a baseline health assessment before employment. Pre-placement medical examinations help determine the fitness of workers for specific jobs and provide baseline health data. This allows comparison with future medical findings to identify any changes in health status due to occupational exposure. For example, lung function tests for workers exposed to dust or audiometry tests for workers exposed to noise establish reference values. The third step involves periodic
