EPA procedure includes illuminating mercury

The Environmental Protection Agency was expected to put boots on the ground in Armstrong late Tuesday afternoon.

They planned to interview anyone involved in the incident.

They were to use a hand-held device called a Lumex to measure the amount of mercury vapors in the air.

Mercury looks like silver water.

Flashlights would help locate the mercury beads, which are charcoal-colored and smaller than a thumbtack.

"If we need to conduct a clean-up, we'll bring in a contractor who specializes in mercury clean-ups.  The contractor would use vacuums with specialized equipment to separate the mercury from dust and other particles," said Kris Lancaster, a spokesperson for the EPA out of Kansas City.

Lancaster say in its liquid state, mercury can travel easily through floor boards and cracks in concrete.
