Everywhere has a fire protection class rating. Even if there is no fire department within 5 miles of your house you would have a protection class of 10.
Anything with a class "C" rating
4/9
class D fire extinguishers may be used on all fires?

Yakal and Narra from the Philippines! A note to anyone: according to Wikipedia, these trees do exist, but Yakal is critically endangered and has literally next to nothing for info on it (Wikipedia says that it is a plant in the Dipterocarpaceae family, and that it is endemic to the Philippines, AND THAT IS IT)! And Narra is a vulnerably endangered species, Wikipedia has information on it, but they don't say anything about its lumber. Ipe is very rot resistant and is a member of the Ironwood family. I believe that it has a Class A fire rating similar to steel and concrete. It will last outside unfinished and untreated for 30 to 35 years. I recommend Wallaba for fire resistance, especially in roofing applications. Red Diamond Wallaba Shingles have a Class A Fire Rating and have a 50+ year life expectancy without any chemical treatments.
Happy Jack holds an ISO fire protection class rating of 5 if your house or building is within 1000 ft of a fire hydrant. If you are beyond 1000 ft of a hydrant, the rating goes up to an 8.
In short, No - in the UK "Class 1" is a form of performance that indicates how easily something burns ('Class 4" being the worst). Fire resistance on the other hand is a term that relates to a construction's ability to resist the passage of fire (e.g. a wall, floor, door etc). The fact that a material is "Class 1" doesn't necessarily have any bearing on its fire resistance performance. For example, PVC cladding can be obtained to a 'Class 1' rating, but it wouldn't contribute much to the wall's fire resistance performance at all.
Use extinguishers with a class B rating. They are intended for use on burning liquids.
Yes
Certainly, there are several local companies who are retailers for shingle roofing purchases. Although, today there are more green materials to cover your existing roof; shingles are still covered under your home owners insurance if found to be damaged by wind, hail, or fire under a covered policy.
By an extinguisher with a C rating. The C just means the extinguisher can be used on a live electrical fire.
