California Phlebotomy Certification Practice Exam

If a centrifuge catches on fire while in use, what class of fire should the technician perceive it as?

1. Class A

2. Class B

3. Class C

4. Class D

The correct answer is: Class C

When considering the classification of fires, it's important to recognize that Class C fires involve flammable gases, liquids, or electrical equipment. Since a centrifuge operates using electric power and can potentially ignite when components or insulation fail, it is categorized under Class C. In a laboratory or medical setting, phlebotomy technicians frequently work with electrical devices. A fire originating from a centrifuge, which is an electrical piece of equipment, poses a risk associated with the electrical nature of its components. Therefore, if a centrifuge catches on fire while in use, perceiving it as a Class C fire is appropriate because it involves electrical hazards. On the other hand, Class A fires involve ordinary combustibles like paper and wood, Class B fires concern flammable liquids and gases, and Class D fires are related to combustible metals. The focus on the electrical aspect of a centrifuge's operation makes Class C the most relevant categorization for assessing the type of fire risk present.
