Hand held flares are approved for which conditions?

Hand-held flares are approved for use in emergency situations such as maritime distress signaling, where visibility and location need to be communicated to rescuers. They are also used in aviation emergencies and certain outdoor scenariOS, like wilderness survival, to signal for help. However, their use is regulated and should be done in accordance with local laws and safety guidelines. Always ensure you are familiar with the specific regulations governing flare use in your region.
