Safety First! Don’t Touch

Blasting Caps are detonators. They contain a small amount of blasting powder and are designed to explode with tremendous force. Their purpose for trained operators is to set-off a larger explosive such as dynamite. Blasting caps are Labeled "Dangerous – Blasting Cap – Don’t Touch."
If you find a blasting cap, DON’T TOUCH! Call your local police or fire department immediately to report it. In unskilled hands, blasting caps are deadly. They can mutilate fingers, cause blindness and deafness – or kill!

A Few Major Projects.

To demonstrate how explosives have helped shape our world, we can look to some well known projects that would not have been possible without the use of explosives.
Three tunnels were constructed by the use of explosives and even today stand out as benchmarks in the history of explosives:

Mount Cenis, a 13-kilometer railway tunnel driven through the Alps between France and Italy (1857-71)

The 6.4 kilometer Hoosac Railway Project

The Sutromine Development Tunnel in Nevada (1864-74).
