Final answer:
Fire extinguishers suitable for Class C fires can be identified by a blue circle with a capital letter 'C' inside. This symbol indicates their suitability for electrical fires, ensuring that users can quickly identify the correct extinguisher type during emergencies.
Explanation:
Fire extinguishers suitable for Class C fires, which are fires involving electrical equipment, can be identified by special markings or symbols that indicate their suitability for electrical fires. Class C fire extinguishers are non-conductive and are safe to use on or near electrical equipment. The National Fire Protection Agency (NFPA) 704 Hazard Identification System provides information about the flammability, reactivity, health, and other hazards of substances but does not directly apply to the identification of fire extinguisher classes. However, for Class C fire extinguishers, they generally have a blue circle with a capital letter 'C' inside it. This symbol is crucial in a quick identification system designed for emergency situations, such as those fire responders might encounter. It's important to ensure that the correct type of fire extinguisher is used for the specific class of fire to prevent worsening the situation.
