Tool control, calibration records and out-of-tolerance findings

Skills you'll practise

• Record the checkout and return of shared and special tools and count tools before closing up equipment
• Report a lost, damaged or dropped tool or instrument straight away and take it out of use
• Read a calibration label and certificate: instrument ID, due date, as-found and as-left results, traceability and accreditation
• Decide from its calibration status and condition whether an instrument may be used on a given job
• Respond to an out-of-tolerance finding: quarantine, report, and identify the jobs measured since the last good calibration
• Take torque and other critical values from the manufacturer's documentation, not memory
