# Physical Hazards and Risks to Healthcare Workers Healthcare workers operate in environments where they are exposed to a wide range of physical hazards while providing care to patients. Hospitals, clinics, laboratories, emergency departments, operating theatres, diagnostic centres and waste-management areas contain numerous sources of injury and occupational illness. Worker safety and patient safety are closely interconnected because an injured, fatigued or exposed healthcare worker may be less capable of providing safe and effective care. Therefore, identifying physical hazards and controlling occupational risks are essential components of healthcare safety. Physical hazards are environmental conditions, equipment-related dangers or workplace factors that can cause bodily injury, illness or impairment. Healthcare workers include doctors, nurses, laboratory technicians, pharmacists, radiographers, physiotherapists, ambulance personnel, cleaners, waste handlers and other support staff. Their exposure varies according to their duties, but several physical hazards are common across healthcare settings. One major physical hazard is slips, trips and falls. Healthcare facilities frequently have wet floors because of cleaning, spilled fluids, leaking equipment or accidental discharge of bodily fluids. Floors may also become obstructed by electrical cables, medical equipment, oxygen tubes, waste containers and improperly stored materials. Healthcare workers may move rapidly during emergencies, increasing the likelihood of falling. Falls can result in fractures, sprains, head injuries and back injuries. They can also affect patients because a worker who falls while transporting a patient or handling medication may accidentally cause harm to the patient. Manual handling and patient movement are another important source of physical risk. Healthcare workers regularly lift, transfer, reposition and transport patients, sometimes under difficult circumstances. Moving patients who are unconscious, immobile, obese or physically dependent can place considerable stress on the muscles and joints. Repeated lifting without appropriate techniques or mechanical aids may cause musculoskeletal disorders, particularly lower-back pain, shoulder injuries and neck problems. Such injuries may reduce the worker's ability to perform duties and may indirectly compromise patient care. Needlestick injuries and injuries from sharp medical instruments represent significant occupational hazards. Although
