Key takeaways

Using Ground Fault Interrupters (GFIs) in wet areas is essential for preventing electrocution from older appliances, which can exceed 32 milliamps—more than five times the lethal limit.
The myth of killer quicksand is grounded in reality; it can pose a danger when fine sand is oversaturated with water, enabling it to behave like a liquid.
Understanding that amperage, not voltage, is the critical factor in electrocution risk, with a lethal threshold of just 6 milliamps across the heart.
The myth that tattoos can explode in MRI machines due to metallic inks is debunked; while some interference occurs, there is no significant danger.
Upgrade your appliances in bathrooms to ensure they have GFIs, significantly enhancing your safety against electrocution.
Educate yourself on the conditions that lead to quicksand formation to better understand and avoid potential hazards in natural settings.
