How Often Should Periodic Inspections Be Performed? Timeframes Based on Equipment.
Periodic inspection how often How it will be done varies depending on the type of equipment and the standard applied. General rule: Unless otherwise specified by the standard or manufacturer, at least once a year. Below you will find a practical summary based on the equipment.
Frequency of periodic inspections on an equipment basis
| Equipment / system | General inspection range | Rest |
|---|---|---|
| Electrical installation, grounding, lightning rod. | Once a year | Electricity/Grounding Regulations |
| Residual current protection (RCD) | Once a year (+ test button regularly) | Relevant regulation |
| Forklift / stacker | Once a year | TS ISO 5057, Work Equipment Management. |

⚠️ This table is a general guideline. The exact interval varies depending on the type of equipment, intensity of use, manufacturer's instructions, and applicable standards. More frequent checks are recommended under intensive or demanding conditions.
What determines the range?
- Relating to regulations and standards (Annex III and equipment standard)
- Manufacturer's instructions (can predict a shorter range)
- Usage intensity and risk (more frequent in challenging conditions)
- Detected in the previous inspection findings
