Final answer:
Uneven surfaces are the leading cause of slips, trips, and falls.
Step-by-step explanation:
Slips, trips, and falls can be caused by a variety of factors, but the leading cause is often uneven surfaces.Uneven surfaces, such as cracked sidewalks or rough flooring, can easily cause someone to lose their balance and fall.
While wet floors, poor lighting, and lack of handrails can also contribute to slips, trips, and falls, it is the uneven surfaces that are most commonly responsible.
On a dry day, static electricity is more prevalent due to the low humidity levels. The rubbing of shoes against a rug generates electrical charges through a process known as triboelectric effect. Humidity normally allows for charges to dissipate into the air because water molecules in the air conduct electricity, which reduces the accumulation of charges on a person's body. However, when the air is dry, it lacks sufficient water vapor, which means the charges that develop from friction while walking on the rug can't easily dissipate. Consequently, these charges build up on the person's body until they discharge upon touching a metal object, causing the familiar spark and slight shock.
