Hi, this is Deputy Chief Henry Watson with the New Bern fire and rescue, in New Bern,
North Carolina. In this session, we're going to look at the three major types of fire extinguishers,
and their advantages. The first type of fire extinguisher is a water based fire extinguisher.
The water based fire extinguisher can be easily identified by the silver can that it comes
in. Some of its advantages are that it absorbs large amounts of heat, and the water is readily
plentiful. Dry chemical fire extinguishers or multipurpose fire extinguishers has a working
range of twelve to eighteen feet. The powder inside the extinguisher has a consistency
of baking flour, some of its advantages is that it is an inert material and can be used
on electrical fires. The third type of fire extinguisher is a C02 fire extinguisher or
carbon dioxide. Some of its advantages are that it has a high expansion ratio and that
it is non-conductive. And, these are the three major types of fire extinguishers.
