Which environmental factor is known to increase the risk of shock or electrocution?

High humidity is known to increase the risk of shock or electrocution due to its ability to promote conductive pathways. When humidity levels are elevated, moisture in the air can condense on surfaces and materials, creating an environment where electrical current can travel more easily. This is particularly critical for electrical systems and appliances, as moisture can bridge gaps between conductive surfaces and create unintended pathways for electricity, raising the potential for shock.

In addition, high humidity can cause corrosion of electrical components, which may lead to shorts and further increase the risk of electrical hazards. In contrast, environments with low humidity or arid conditions typically have less moisture to facilitate conductive pathways, thus lowering the risk of shock or electrocution. Cold temperatures can also contribute to certain risks, but they primarily affect the behavior of materials and personnel rather than directly increasing electrocution risk in the same way that high humidity does.
