# Tool crib software that stops an expired instrument reaching a critical job

> A tool crib is the controlled store where tools and calibrated instruments are issued to workers and returned after use. NIST maintains the national measurement traceability chain those calibrations depend on, and there are roughly 899 US establishments running cribs of meaningful size. Neurobird tracks every tool to a holder, blocks issue when calibration has expired, and keeps the certificate with the tool.

## What Neurobird Tool Crib Management does

- Issue and return tools against a person, not a sign out sheet
- Block issue of a tool whose calibration has expired, before it reaches a critical job
- Hold calibration certificates with the tool they belong to
- Show what is genuinely on the shelf so purchasing stops buying duplicates

## How it works

1. **Register the tool** Each tool carries an ID, a calibration interval and its certificate, so its status is a fact rather than a sticker.
2. **Issue against a holder** Checkout records who has it and when it is due back, so the tool has a location that is not just missing.
3. **Block on expiry** A tool past its calibration date cannot be issued for controlled work, which is the moment the control actually matters.

- **899** Approximate US establishments operating tool cribs of meaningful scale within maintenance and industrial operations. (source: US Census County Business Patterns, https://www.census.gov/programs-surveys/cbp.html)
- **1901** Year NIST was founded as the national measurement institute, which is how long traceable calibration has been formalised. (source: NIST, https://www.nist.gov/about-nist)

## Questions

### What is a tool crib?

A tool crib is a controlled store for tools, instruments and equipment issued to workers and returned after use. In industrial maintenance it typically holds calibrated instruments, specialist tooling and high value items that must be tracked to a holder.

### Why does calibration tracking matter?

Because a measurement made with an out of calibration instrument is not evidence. In regulated and quality controlled work, using an expired instrument can invalidate the inspection or the torque record it produced, and that is usually discovered during an audit.

### How much tool loss is normal?

Losses vary, but uncontrolled cribs commonly lose a meaningful share of small tooling annually. The larger cost is usually duplicate purchasing, because nobody can see current stock.

### Does this replace our CMMS?

No. A CMMS manages the asset being maintained. This manages the tools used to maintain it, including who holds them and whether they are in calibration.
