How to safely set off flash-bang firecrackers?

1. Always place the firecracker on the ground before lighting Set the firecracker firmly on the ground first, then light it. Never hold it in your hand—even if it seems small and harmless. Move away to a safe distance immediately after ignition. 2. Read the manufacturer’s instructions Every pyrotechnic product comes with instructions for a reason. Different products may have different ignition methods, delay times, and recommended safety distances. It’s always worth taking a moment to read the instructions before use. 3. Ignite only in open spaces Sound-emitting products should be ignited outdoors only, away from buildings and vehicles, windows, flammable materials, people, and animals. Do not use firecrackers indoors, on balconies, stairwells, or in any enclosed spaces. 4. Keep a safe distance After ignition, move away immediately; do not lean over the product or try to watch it up close. Size doesn’t matter—even small items generate a very strong sound impulse. 5. Dud—wait at least 15 minutes If the product fails to go off, wait at least 15 minutes. Do not try to relight it or tamper with it. A dud may detonate with a delay and poses a real danger. 6. Firecrackers don’t explode on their own Firecrackers do not detonate spontaneously. They won’t explode in pockets, bags, or packaging—detonation requires an ignition source such as a fuse, strike strip, or flame. Even so, store them responsibly and according to the manufacturer’s recommendations. 7. Use products as intended Do not modify pyrotechnic items, combine multiple firecrackers, or use them contrary to the instructions. Sound emitters, bang strings, and launchers have specific uses that must be followed. 8. Alcohol and pyrotechnics don’t mix Pyrotechnic products should be ignited sober and clear-headed. Alcohol reduces reflexes, impairs distance judgment, and slows reaction time, significantly increasing the risk of an accident. 9. Mind your surroundings Before lighting, make sure there are no bystanders nearby, secure animals, and inform people in the area about your plan. This is especially important for high-noise products. 10. Proper storage matters Store firecrackers and sound-emitting products in a dry, cool place, in their original packaging, and out of children’s reach. Do not store them near heat sources or in areas exposed to moisture. 11. Use only legal products Use only CE-marked items approved for sale in the European Union and sourced legally. Illegal or modified products are among the most common causes of accidents.
