Why does my fire extinguisher have a damaged or unreadable inspection sticker?

A damaged or unreadable inspection sticker makes it harder to confirm whether the extinguisher has been serviced on time. Because the manuals say maintenance records and inspection marks are important, do not treat the unit as fully verified if the sticker has peeled, blurred or gone missing. fileciteturn0file7turn0file8

1. Check whether the sticker is the only missing item or whether the cylinder label is also damaged. Expected result: the extinguisher should still be clearly identifiable. If both markings are compromised, safe use becomes uncertain. fileciteturn0file7turn0file8
2. Look at the surrounding surface for moisture, heat damage or cleaning residue. Expected result: the sticker remains firmly attached and readable. Conditions that damage the sticker may also damage the extinguisher’s finish.
3. Compare the visible inspection information with the overall condition and age of the product. Expected result: there is a clear maintenance history. If you cannot confirm that, treat the extinguisher as unverified.
4. If the inspection sticker cannot be read and you cannot be confident the extinguisher is still in date, stop using it until it has been checked. If safe use is uncertain, contact the retailer or store where the product was purchased. fileciteturn0file8turn0file7
