Definitions of "punk" on the Web:

* A slow burning wick for lighting the fireworks.
www.fireworks.com/safety/glossary.asp

A punk is a stick used for lighting firework fuses. It is safer than a match or a lighter because it can be used from a greater distance and does not use an open flame. Punks often resemble sticks of incense.They're made of bamboo and a brown coating.

Insulation-related incidents are some of the most common types involving organic HTF systems. Typically, a leak occurs at a flange or instrument connection and soaks into the pipework insulation (e.g., calcium silicate, Fibreglass, mineral wool). Eventually the saturated insulation is ignited when the circulating fluid and the piping heat the HTF and, in the presence of air, slowly oxidise the fluid. This produces low AIT components which results in a "punking" type fire. This fire can act as an ignition source for other fires.
