Their vibrant colours and eye-catching bursts can make you forget how dangerous fireworks can be. But on June 23, 2006 — St-Jean-Baptiste Day or Fête nationale — about 50 people north of Montreal, Que., got a sobering reminder.

During the festivities, people in Terrebonne, Que., set off fireworks in a backyard. One of the colourful explosives hit the roof of a nearby home that was under construction. The flames spread rapidly, damaging six homes and causing about $1 million in damages. Luckily, no one was hurt as 49 firefighters battled the flames.

It is for this reason that the Explosives Act, administered by the Explosives Regulatory Division (ERD) of Natural Resources Canada, restricts the sale and purchase of fireworks and recommends safety precautions.

Canada allows fireworks in two categories: display and family or consumer. Display fireworks can only be set off by experienced, licensed adults and crowd supervision is mandatory. Organizers need a permit. More than 16,500 Canadians are licensed to conduct exhibition fireworks demonstrations, according to the Canada Safety Council.

Family or consumer fireworks are those used by the general public. Some common types of these fireworks are:

Type	Effect
Roman candles	Emit balls or stars at intervals.
Wheels	Fireworks mounted on wheels rotate at high speed because of rocket effect.
Fountains	Produce a shower of sparks, sometimes called a volcano.
Barrages	Multiple fountains or roman candles. May explode high in the air or produce starburst.
Sparklers	Produce intense heat and light, high temperatures for approximately two minutes.

They are designed for recreational use by the public, but there are safety procedures that people should follow when celebrating the holidays with a pyrotechnic show at home.

Safety procedures:

Buying and storing

Follow the Laws. The ERD has explosive regulations governing the use of fireworks, but provinces, territories or cities may have their own regulations, such as restricting the purchase and use to certain times of the year. People must be at least 18 years of age to purchase fireworks.

Buy fireworks only from reliable dealers. ERD has lists of authorized fireworks manufactured in Canada and abroad. A bilingual label is another indication that fireworks are authorized. Do not use or smuggle fireworks from another country because the quality is questionable and they may be a safety hazard. Making your own fireworks is not recommended.

Store fireworks properly. Keep them in a cool, dry place away from children. Check to see if there are any special handling instructions. Ten kilograms gross weight is the maximum amount that can be stored in a dwelling. Amounts larger than that must be kept in a separate, locked building.

Transportation. Fireworks must be transported in a vehicle's trunk, not the passenger compartment. If your vehicle doesn't have a trunk, put fireworks in a container with a lid. Do not smoke while loading, transporting or unloading fireworks.

Getting started

Set-up. Use fireworks outdoors, never indoors. That goes for sparklers, too. The Canada Safety Council says sparklers can burn as hot as 650 F and recommends they be used outdoors — on a driveway, sidewalk or other fire-resistant surface. It recommends sparklers be used under adult supervision. Once they've burned, they should be doused and placed immediately in a metal container. The council recommends not substituting sparklers for candles on a cake.

Choose a clear, open area. The area should be far away from buildings, vehicles, overhead obstructions and dry brush or grass. There should be a minimum clear area of 30 metres by 30 metres for aerial family fireworks, like roman candles, and 20 metres by 20 metres for fountains and other ground-based fireworks.

Check for wind. Fireworks should be lit with the winds blowing away from spectators. If winds are strong, do not set off fireworks.

Have water nearby. A bucket or a filled hose should be kept nearby in case of emergency.

Read all instructions. Directions for each of the fireworks should be read in advance.

Use ground-based fireworks on a hard surface. Ground-based fireworks, like fountains, should be lit on a hard, flat surface to make sure the fireworks are stable. On grass, plywood should be laid down first.

Bury aerial fireworks. For roman candles, bury (do not pile) the device to half its length in the ground or in a large pail or box filled with earth or sand.

Keep spectators safe. All onlookers should be at least 20 metres away from the fireworks.

Setting off fireworks

Use proper eye protection and clothing. Wear safety goggles or safety glasses. Regular glasses or sunglasses do not provide adequate protection and could potentially make injuries worse. Wear non-flammable clothing such as cotton. Do not wear synthetic fabrics such as nylon or polyester.

Keep children away. Do not let children handle or play with fireworks, even sparklers.

Use care when handling fireworks. Do not drop them or smoke while handling fireworks. Do not carry them in pockets.

Use care when setting off fireworks. Only one person should be in charge of lighting fireworks. When lighting fireworks, do not put any part of your body over the fireworks or touch them with your hands. Never point or throw them at people. During the show, keep unused fireworks away from the firing area and cover them to keep from setting them off by accident.

Duds or misfires. Never try to re-light fireworks that have misfired. Wait 30 minutes, then dunk them in a bucket of water.

Clean up afterwards. Wait half an hour after the show has finished. Then check the area for duds and clean up debris. Check again the next morning.
