A leaking AA alkaline battery. Alkaline batteries use manganese dioxide and zinc electrodes with an electrolyte of potassium hydroxide.The alkaline battery gets its name from the replacement of the acidic ammonium chloride of zinc–carbon batteries with potassium hydroxide, which is an alkaline.
Alkaline batteries are prone to leaking potassium hydroxide, a caustic agent that can cause respiratory, eye and skin irritation. [note 1] The risk of this can be reduced by storing batteries in a dry place and at room temperature. Damage from leakage is mitigated by removing batteries when storing devices.
Skin depth depends on the frequency of the alternating current; as frequency increases, current flow becomes more concentrated near the surface, resulting in less skin depth. Skin effect reduces the effective cross-section of the conductor and thus increases its effective resistance. At 60 Hz in copper, skin depth is about 8.5 mm. At high ...
Battery explosions can be caused by thermal runaway and may cause burns or other injuries. [87] Nicotine poisoning can occur by ingestion, inhalation, or absorption via the skin or eyes. [12] [88] [89] E-liquid exposure can come by leaks or spills. [90] A 2018 review concluded that exposure to vapor can reduce lung function. [91]
Electrical burn on hand. An electrical burn is a burn that results from electricity passing through the body causing rapid injury. Approximately 1000 deaths per year due to electrical injuries are reported in the United States, with a mortality rate of 3-5%.

The characteristics of the skin are non-linear however. If the voltage is above 450–600 V, then dielectric breakdown of the skin occurs. [21] The protection offered by the skin is lowered by perspiration, and this is accelerated if electricity causes muscles to contract above the let-go threshold for a sustained period of time. [14]
