NCCER Level 4 Practice Exam

If failure would have no effect on patient care, it is categorized by NFPA 99 as which category?

Category 1 Category 2 Category 3 Category 4

Correct Answer:

Category 4

Explanation:

NFPA 99 uses risk categories to classify equipment by how a failure would affect patient care. The scale goes from higher risk to lower risk, with Category 1 handling the highest risk and Category 4 the lowest. If a failure would have no effect on patient care, it belongs to the lowest-risk group. This helps determine how often something needs testing, maintenance, or redundancy. So when there’s no impact on patient care from a failure, the appropriate category is Category 4. The other categories cover scenarios where failures could affect patient safety or care, requiring more stringent monitoring and maintenance.
