Reasons why ABC fire extinguisher does not respond to class k fires?
ABC fire extinguishers, which contain dry chemical powder, are ineffective against Class K fires for a couple of reasons. Class K fires involve burning cooking oils and fats that reach higher temperatures than other liquid fires. An ABC extinguisher would struggle to quench such high-temperature fires due to its lack of adequate cooling power. Furthermore, the dry chemical powder only inhibits the combustion process and isn’t sufficient to fully extinguish Class K fires.
