[H. L. Chauvin]

Per Tom's good advice in Reply #4 ..... (i.e., always try to hook up cables, away from the battery) ..... I saw a guy removing battery charger cables from a large truck where the top of the battery was up high at his chin level with all battery acid caps screwed on.

A spark from his charger cable ignited the battery gas, the battery exploded, blew the entire top off of the battery, and acid went all over his face & head & down his neck.

Luckily, there was a water hose and hose bibb within 6 feet where I was able to immediately rinse off his face, head & neck ....... poor soul was unharmed because of having water nearby to rinse off the acid.
