When is pyrotechnics typically replaced?

Pyrotechnics have a finite shelf life. Over time, chemical stability can degrade, moisture and temperature exposure can affect ignition reliability, and performance may drop so the signal cannot be trusted when needed. To ensure a dependable distress signal, standards set a replacement interval from the date of manufacture. The typical period is 42 months from when the device was made, roughly 3½ years. This duration balances keeping signaling gear effective with practical inventory management. After that date, manufacturers can’t guarantee performance, so replacement is required. Always check the date printed on the device and replace before expiry.
