How do Fireworks
work?
|
The basic ingredient of fireworks is black powder – also
known as gunpowder. The “paints” used by a craftsman of a
pyrotechnic device are the different chemicals added
during production. These chemicals provide the dazzling
array of colors and visual effects on the night sky, as
well as the sounds (reports) that accompany the burns.
The manufacturer carefully selects the chemicals to be
used and determines the order in which they are packed
into the casing in an effort to create a specific visual
effect. Once the materials are packed into the casing, a
fuse is affixed so that the device can be safely ignited.
Although all of the colors and effects of a fireworks
display are spectacular, the hallmark of a truly fine show
are deep blue or dazzling white bursts. |

What the different
classifications of fireworks: |
|
Consumer Fireworks
(formerly known as “Class
C” fireworks) - Also known as 1.4G fireworks. These devices
are most commonly sold at neighborhood stands during the
Fourth of July season. “Consumer”
fireworks include cone fountains, cylindrical fountains,
roman candles, skyrockets, firecrackers, mines and shells,
helicopter-type rockets, certain sparklers and revolving
wheels. |

|
Display Fireworks
(formerly known as “Class B” fireworks) – Also known as 1.3G
fireworks. These are the fireworks used in large community
displays run by licensed professionals (pyrotechnicians).
These devices are not intended for use by consumers. |
| |
|
Stay away from illegal explosives. Illegal explosive
devices continue to cause serious injuries around the Fourth
of July holiday. These devices are commonly known as
M-80’s, M-100’s, blockbusters or quarter-pounders. |

| How do I recognize
illegal fireworks? |
|
Look for a manufacturer’s name on each item or on the box in
which they were packaged. Each device should also list
instructions for proper use and have cautionary labeling.
Law requires the manufacturer’s name and cautionary
labeling. Fireworks without this information are probably
illegal and therefore, to be avoided. If you suspect that
you have illegal fireworks, contact the Bureau of Alcohol,
Tobacco, and Firearms at 1-888-ATF-BOMB. |
