One new trend is that is being seen according to the Wall Street Journal is that people are using DNA purchased via the Internet to do home development of new organisms for everything from cancer cures to Bio Fuels. Specifically it mentions using an Iguana heater and other equipment purchased on Ebay to build hot boxes. Besides the source of ignition, what are the potential health hazards here. If you go in on a medical or service call even. I have not heard of a "Close Call" involving one of these, yet. Maybe my email should have gone there instead of to you. It may not be a huge hazard but increasing awareness may help alleviate the fear when a company or unit comes upon one of these. I am old enough to have gone through the AIDS scares and emergency personnel's reactions to the unexpected from it's beginning. I hope you understand my concern and desire to raise this issue.
