An inspection sticker on a fire extinguisher is much more than just a simple sticker. It documents regular maintenance and provides information about the next scheduled inspection. This makes it an indispensable part of operational and private fire protection organization. The sticker creates transparency and verifiability for authorities, insurance companies, or in the event of damage.
What information does the inspection sticker contain?
The inspection sticker provides information at a glance about:
- Date of last inspection
- Due date of next inspection
- Company that performed the maintenance
- Name of the expert
In many cases, it is also color-coded (e.g., by quarter) so that maintenance periods can be quickly identified. Some stickers also contain QR codes for digital inspection reports.


Who is authorized to inspect fire extinguishers and affix inspection stickers?
Only specially trained experts in accordance with DIN 14406-4 are authorized to inspect fire extinguishers and affix a valid inspection sticker. This inspection is usually carried out every two years and is required by law. Unauthorized inspection by laypersons is not permitted and may result in liability issues in the event of an emergency.
Why is a valid inspection sticker so important?
An unmaintained fire extinguisher can fail in an emergency—with potentially serious consequences. In addition, occupational safety laws and fire protection regulations expressly require regular inspections. The inspection sticker therefore also serves as legal protection for companies, operators of public facilities, and those responsible for occupational safety.
How to recognize outdated inspection stickers
Just look at the inspection date: if it is more than two years ago, the fire extinguisher must be inspected immediately by a specialist company. Damaged, illegible, or missing stickers are also a clear warning sign.
