Seguridad eléctrica

La corriente eléctrica que atraviesa el cuerpo humano puede provocar daños en el sistema nervioso, puesto que los nervios funcionan con señales electroquímicas y la corriente eléctrica puede interrumpir éstas.

Cuando el camino de la corriente eléctrica incluye nervios que controlan el suministro de oxígeno, la situación presenta riesgos fatales.

Los efectos de la corriente eléctrica dependen de la intensidad de la misma:

Reacción fisiológica
apenas perceptible
3 – 5 mA
dolor extremo
35 – 50 mA
parálisis muscular
50 – 70 mA
parada cardíaca
500 mA
