What is an added danger of receiving a 12 mA shock?

Receiving a 12 mA electric shock poses an added danger because it can lead to involuntary muscle contractions, potentially causing the individual to be unable to let go of the electrical source. This prolonged exposure increases the risk of severe injuries, such as burns or cardiac issues, including arrhythmias. Additionally, the perception of pain and the body's response can vary widely, making it difficult to predict the outcome for different individuals. Overall, even relatively low levels of current can be life-threatening under certain conditions.
