How long are pyrotechnics generally good for?

Pyrotechnics, such as flares and signal devices, typically have a shelf life of about three years from the date of manufacture. This time frame is established by the manufacturers and is based on the chemical stability of the compounds used in these devices, as well as the materials and conditions that can affect their performance over time.

After this period, the effectiveness of the pyrotechnics can diminish, leading to potential safety hazards in critical situations where signaling might be required. It is important for boaters to regularly check the expiration dates on their emergency signaling devices and to replace them as recommended to ensure they function properly when needed. Following the three-year guideline helps ensure that the equipment is reliable and compliant with safety regulations.
