Ergonomic aspects of electric shock risk in the conditions of an underground mine

Author: P. Gawor

The risk of electric shock in an underground mine should be considered with regard to ergonomic aspects.

Narrow excavations, usually with large amounts of electrical equipment increase the risk of persons on situ making contact this equipment with different parts of the body.

The risk of electric shock should be then considered in the context of the possibility of different shock-current paths.

An analysis of the effects of an electric current on the human body during an accident caused by touching by any two body points is carried out in the article.

A method of calculating factors affecting the severity of the shock by alternating current (a.c.) and direct current (d.c.) has been suggested.

These factors describe the different effects of an electric current passing through a human body along the most common paths.
