<FontFamily><param>Courier New</param><bigger>S<FontFamily><param>Times New Roman</param>ome years ago I heard a lecture from a medical microbiologist 
who had done all sorts of experimental work on the safety of 
microbiology methods.

One finding I remember particularly well was that an area 
around a lighted Bunsen burner was sterile to a distance of some 
8-10 inches (25cm?), even when being used to sterilise loops, 
etc that had been used to pick up colonies or pus and other 
infected material.

Surprisingly effective!
