The easiest thing you can do is make your neighbors aware before setting off any fireworks. Talking to your neighbors individually or simply sending out a text to whatever platform your neighborhood communicates on can make a world of difference for people with PTSD and pet owners.
It is important to follow the laws regarding fireworks around you. Sometimes people with PTSD purposely live in areas where fireworks are limited or banned, so setting them off illegally can be extremely triggering.
Using silent or quiet firework alternatives can prevent PTSD episodes all together. Examples of alternatives are glow sticks, confetti poppers, bubble wands, outdoor projection lights, and drone light shows. Outdoor projection lights are relatively cheap to buy and can be used over and over again.
