# The inspections that fall due by calendar

_Nobody skips an inspection on purpose. They get missed because the reminder lived in the head of whoever retired._

**Responde a:** mandatory periodic equipment inspections · statutory inspection overdue · tracking legal maintenance of installations · who keeps track of machinery inspections

Every industrial site has an invisible list: the compressor, the overhead crane, the electrical installation, the extinguishers, the forklift, the boiler. Each with its own frequency and its own company that comes to look at it. Nobody forgets them out of negligence; they get forgotten because the list is not written anywhere and lives split between three people's memory and a wall calendar.

## The four ways to end up late

| How it happens | How it looks from inside |
| --- | --- |
| The inspecting company stopped calling | «They used to remind us» |
| The inspection happened but no report arrived | «It's done, they'll have the paper» |
| The responsible person changed | «That was handled by the one who left» |
| A new machine was bought | It never entered any list, because the list was mental |

> [!IMPORTANT]
> The second row is the most dangerous, and the one almost nobody counts as a problem: **an inspection whose report is not in your files is, for the purposes of proving it, an inspection that never happened**. It does not matter that the machine is perfect and the technician came on a Thursday. When someone asks —an inspector, an insurer after a claim, a client auditing— what gets shown is the paper. Chasing the report is part of the inspection, not a later formality.

## The list, which is the whole job

1. **One line per equipment or installation, not per supplier** — Suppliers change; the equipment stays.
2. **With its frequency and the date of the last one** — The next one follows by itself, with nobody calculating it.
3. **The report filed with the equipment's record** — Not in the inbox of whoever received it.
4. **And an alert with enough lead time to book** — Warning on the expiry date is useless: you have to call, find a slot and wait.

> [!WARNING]
> Buying or hiring equipment is where this collapses, and both cases are avoidable. **On buying**: the machine arrives, goes into production, and nobody adds it to any list — months later nobody knows whether anything is due. **On hiring**: it is assumed inspections are the owner's, which is usually true and still does not free you from holding the paper; if the hired machine fails at your premises, what you will be asked for is the documentation, not the hire contract.

## What you gain by having it in place

**En corto**

- You stop discovering what has lapsed on inspection day, when there is no margin left.
- You can book with time, which nearly always means booking cheaper.
- An incident does not become two problems: the incident, and being unable to evidence the maintenance.
- And a change of responsible person stops being a six-month hole.

> [!NOTE]
> Which equipment and installations are subject to mandatory inspections, how often, who may carry them out and what must be kept depends on the equipment type and the applicable industrial rules. **Your maintenance provider or adviser settles that**; here we cover what always fails the same way: the list and the filing.

**Is it enough that the maintenance company tracks it?**

It helps, but the paper will be asked of you. Hold it too.

**What about hired equipment?**

Ask the owner for the documentation and file it like your own while it is on your premises.

**What if I find a lapsed inspection?**

Book it now and record when it was spotted: the reaction counts too.

## Ejemplos

**An inspector asks for the last crane inspection report and all that exists is that «it was done».**

- Chases the report as part of the inspection and files it with the equipment record

→ What was done becomes what can also be shown.

**A new machine is bought and six months later nobody knows whether anything is due on it.**

- Registers the equipment on the list the day it arrives, with frequency and alert

→ No machine lives outside the calendar just because it arrived in a hurry.

**The maintenance manager retires and the inspection calendar leaves with them.**

- Moves the list out of one person's head into a shared place

→ A handover stops opening a months-long hole in the control.

**Inspections are remembered from memory.**

- Records each due date with a warning

→ The calendar stops depending on remembering.

**They all fall in the same month.**

- Warns far enough ahead to spread them

→ The calendar spreads out.

**The inspection happens and the certificate stays on paper.**

- Captures it and attaches it to the equipment

→ The certificate lives with the equipment.
