What are the characteristics of pyrotechnic VDSs?

Pyrotechnic Visual Distress Signals (VDSs) are designed for use in emergency situations where a vessel needs to alert nearby boats and aircraft to its location. They generate bright light, smoke, and flames to attract attention effectively. Due to the nature of their composition and function, they must be handled with extreme care. There is a risk of fire and injury if not used properly, which emphasizes the importance of following safety protocols when deploying these signals.

Understanding that pyrotechnic VDSs produce smoke and flames is crucial for safe operation, both for the user and for others in the vicinity. This characteristic differentiates them from other types of distress signals, such as non-pyrotechnic options, which do not have the same hazards.
