The sizes and patterns of fireworks display shells, considering their air openings and fallout zones, in relation to the neighboring environments of the shooting area, are of paramount importance to safety criteria.

In general, the vicinity of the shooting areas must be free from such inflammable materials, as gas stations, dry grasses, hays, leaves and etc. Such areas should have a safety clearance diameter of at least 200 meters or the radius of 100 meters in all directions.

The audience or crowd watching fireworks shows should stay away from the shooting sites, and any unauthorized persons not directly or officially involved with the shooting crews or pyrotechnics team will not be allowed to stay close or near the shooting base.

It is believed that the best distance of watching fireworks is about 100 meters away from the shooting base, whereas the safest distance is from 150 meters onward.

Shooting crews at the Class B shoot line must wear protective clothing and hard hats preferably with safety glasses. Fire fighting as well as any safety equipment should be prompt at hands if deemed appropriate to the surrounding conditions of the shooting sites.

If shooting
Class B fireworks in city or downtown areas, bombing shock waves or sonic vibrations may cause damages to glass windows or glass curtain walls if the shooting base is sandwiched or being surrounded by such glass construction. Shooting base should not be positioned beneath cables such as telephone lines or power lines.
