Explanation:
Falls are the leading cause of death when it comes to home accidents. They make up a third of all fatalities. The elderly are most affected by this type of accident. Fatalities aside, when an elderly person falls the associated problems are far more serious. While younger people may also suffer a broken bone, a broken bone is a far more serious problem for an older person in terms of healing.
Minimize The Risk
Staircases: Keep children safe from tumbling down steps by installing safety gates at both the bottom and top of staircases. Keep everyone safe by making sure the lighting is good and the handrails and steps are solid and well maintained. Elderly people with less mobility should consider installing stairlifts or consider moving to a home without stairs to avoid falls.
