In electrical safety, which condition increases the risk of shock?

• A. High Humidity
• B. Low Humidity
• C. Dry Air
• D. Cold Temperatures

Answer: (A)

High humidity increases the risk of shock because moisture makes skin and surfaces more conductive. When the air is damp, the skin’s resistance drops—wet or sweaty skin can allow much more current to flow for the same voltage compared to dry skin. That higher current through the body raises the likelihood and severity of an electric shock. Surfaces and equipment can also become more conductive when damp, creating additional leakage paths that bypass insulation. In low humidity, dry skin has higher resistance, so less current passes through the body, reducing shock risk. Dry air and cold temperatures don’t raise the shock risk in the same direct way; their effect is much less about increasing current through the body.
