What are the different types of portable fire Extinguishers?
Portable fire extinguishers are categorized by ratings. These ratings determine the size and type of fire that the extinguisher can effectively put out. The three most common classes are A, B, and C. The fourth class is D. Check the extinguisher label and purchase an extinguisher that is appropriate for the type and size of fire you may encounter. Only choose extinguishers that have been tested by an approved testing laboratory and labeled for their intended use (e.g. UL, ULC).
