What is the minimum number of TFIFRM gauge thickness accuracy checks required during an inspection shift?

The requirement for a minimum of three TFIFRM gauge thickness accuracy checks during an inspection shift is grounded in ensuring precision and reliability in fireproofing applications. This number of checks allows for a more robust verification of the gauge’s accuracy over time and various conditions.

By conducting multiple checks, inspectors can identify any deviations from the expected measurements and ensure that the thickness of the fireproofing material meets industry standards. This helps maintain structural integrity by ensuring that materials are applied to the correct thickness, which is critical for fire resistance.

Moreover, having three checks enhances confidence in the consistency of the measurements throughout the shift. It also serves as a safeguard against any potential anomalies that might arise due to factors such as user error or environmental changes. This thorough approach reflects best practices in quality control within fireproofing inspections.
