Fire extinguisher next inspection date calculator

Enter the date of the last inspection and the interval that applies to the unit: the calculator gives you the next due date, the time remaining, and a reminder file for your calendar. Everything happens in your browser — nothing is sent or saved.

Which interval should I pick?

It depends on the type of check: a visual check is often monthly, professional maintenance at least once a year, and in-depth checks (recharge, pressure test) at intervals of several years. Exact durations vary with local regulations, the standard applied and the manufacturer's recommendations: see our article How often should a fire extinguisher be inspected?.

And with hundreds of units?

Calculating one date is easy. Following hundreds of them, across dozens of clients, is much harder. Extinguo works out each unit's next due date as soon as you log a visit, alerts you when one is overdue and reminds your clients on WhatsApp.
