Electrocutions can occur due to contact with live wires or faulty electrical systems, resulting in serious injuries or death.
b. Repetitive Strain Injuries (RSIs):
- RSIs develop gradually over time due to repeated motions, overexertion, or poor ergonomics. These injuries often affect muscles, tendons, and nerves, leading to chronic pain and disability. Common examples of RSIs include:
- Carpal Tunnel Syndrome: Typing on keyboards or performing repetitive hand movements without adequate rest can compress the median nerve in the wrist, causing pain, numbness, and weakness in the hand and fingers.
- Tendinitis: Overuse of tendons, such as those in the shoulders, elbows, or knees, can lead to inflammation and pain. Jobs that involve repetitive lifting, pushing, or pulling are particularly prone to this type of injury.
- Bursitis: Inflammation of the bursae, small fluid-filled sacs that cushion the joints, can occur due to repetitive motions or prolonged pressure on specific areas of the body. Bursitis commonly affects the shoulders, elbows, hips, or knees.
c. Occupational Illnesses:
- Occupational illnesses result from exposure to hazardous substances, environmental conditions, or biological agents in the workplace. These conditions may develop over time due to prolonged exposure, making them harder to detect and treat. Some examples include:
- Respiratory diseases: Workers exposed to airborne pollutants, such as dust, chemicals, or fumes, may develop respiratory conditions like asthma, chronic obstructive pulmonary disease (COPD), or pneumoconiosis (e.g., silicosis, asbestosis).
- Skin disorders: Contact with irritants, allergens, or hazardous substances can lead to skin conditions like dermatitis, eczema, or chemical burns. Workers in industries such as healthcare, cleaning, or manufacturing are at higher risk.
- Occupational cancers: Prolonged exposure to carcinogens, such as asbestos, benzene, or radiation, can increase the risk of developing certain cancers, including lung cancer, mesothelioma, leukemia, or skin cancer.
Understanding the different types of LTIs is essential for implementing targeted preventive measures and creating a safer work environment for all employees.
