CSI California Fire Extinguisher 1 Certification Practice Test – Exam Prep & Study Guide

The presence of a tamper indicator on a fire extinguisher is signified by the intact seal. This seal is typically placed over the handle or nozzle of the extinguisher and serves as a clear visual indication that the extinguisher has not been used or tampered with since it was last inspected or filled. When the seal is broken or removed, it usually indicates that the extinguisher may have been used or accessed, prompting further inspection or maintenance. An intact seal is essential for ensuring the reliability and readiness of the extinguisher in case of an emergency.

While other methods such as color changes or attached tags might provide information about the extinguisher’s status, they don’t specifically indicate tampering as directly as an intact seal does. Weight measurement also does not serve as a direct indicator of whether tampering has occurred and is more relevant for assessing if the extinguisher is still filled to the proper levels.
