Accidental falls can be attributed to physical factors, such as footwear, surface material, surface contamination, slope, lipped footpath cracks and lighting conditions, which can be minimised or improved through design, installation, maintenance, safety audits, policy and legislation. An individual’s response to environmental factors may also be affected by factors which increase the risk of slipping, for example, age, impaired vision, general health, stress, fatigue, drug and alcohol use and activity e.g. carrying, pushing, rushing.
