What is the minimum thickness of ice required for one person to walk safely?

• A. 2cm
• B. 5cm
• C. 7cm
• D. 10cm

Answer: (B)

The minimum thickness of ice required for one person to walk safely is 5 cm. This measurement is based on safety assessments related to weight distribution and the potential for structural integrity of the ice. Ice that is at least 5 cm thick has proven to provide adequate support for the average person's weight, minimizing the risk of breaking through. Thicker ice, such as 7 cm or 10 cm, can support more weight and is generally safer for additional activities, but for a single individual's safety, 5 cm is the key threshold recognized by outdoor safety guidelines. It is important to be aware that ice can be unpredictable, influenced by factors such as temperature fluctuations, water currents, and snow cover, which can affect its thickness and stability.
