The Coast Guard requires boats to have at least one B-1 marine fire extinguisher on board. Depending on the size of your boat you may need more than one. Boats less than 26' have to have at least one B-1 fire extinguisher on board.
Graphite is a mineral composed exclusively of the element carbon. Graphite has the same chemical composition as Diamond, which is also pure carbon, but the molecular structure of Graphite and Diamond is entirely different.This causes almost opposite characteristics in their physical properties. Graphite is rather common mineral, but fine crystals are rare.Most Graphite mining areas produce enormous quantities from a single or several large Graphite vein s, but collector specimens in good crystals are not commonly encountered. Rare hexagonal polymorph of Graphite and Diamond formed only in a meteoric environment where extreme heat and pressure caused it to form. To date, it is only found in Mottigen, Ries Crater, in Bavaria, Germany. As it differs in crystal structure, Chaoite is scientifically categorized as an individual mineral species.
The most common use of graphite, as a great deal of schoolchildren know, is as lead in pencils. Pencil lead is made from the slag (the not so fine crystals of graphite) mixed with clay.However, the finer crystals of graphite are often sought after and used in electrical components, as graphite is one of the only conductors of electricity that is not metallic in origin.hough graphite is chemically similar to diamond, its physical qualities are very different. Graphite is usually found in brittle, inflexible flakes; graphite is dark and greasy to the touch, smudging readily on objects.
