An Industrial Accident can be categorized into two categories: external and internal. An external accident affects the environment around the factory. External accidents can take the form of fires, chemical spills, discharges of toxic gases and radiation. These types of accidents can be huge disasters with effects that cross international boundaries. Causes of these Industrial Accidents include: organizational errors, human factors, component failures, deviation from normal operational conditions, software defects, outside interference and natural forces.
An internal Industrial Accident affects the people within the factory or work site. Internal accidents can involve transmission machinery, metalworking machines, woodworking machines, agricultural machines, construction machinery and equipment, textile machines, tire-making machines, food-making machines, printing machines, lifting equipment, pressure vessels, furnaces, refrigerators, hand tools, ladders and scaffolding.
