Industrial Incidents Caused by Instrumentation Failure¶
Instrumentation failures — failed sensors, miscalibrated transmitters, and control loops that were out of service — deprived operators of the information needed to detect abnormal conditions before they escalated. CSB investigations document how instrument failures combined with operator overconfidence in displayed readings contributed to delayed responses and loss of containment.

Common Patterns¶
Across these 15 investigations, the CSB consistently found instrumentation failure alongside these co-occurring failure modes, industries, and hazard types:
Co-occurring failure modes: Design Deficiency · Training Deficiency · Procedural Failure · Maintenance Error · Human / Operator Error
Primary industries: Chemical Manufacturing, Petroleum Refining, Wastewater Treatment
Associated hazard types: Chemical Release · Fire · Explosion · Structural Failure
