SPECIAL EFFECTS GONE BAD!!!
WEST WARWICK, Rhode Island (CNN) -- At least 26 people are dead after a concert's pyrotechnics apparently ignited a massive fire that destroyed a Providence-area nightclub late Thursday, officials said.
Many of the victims apparently perished after they frantically rushed the club's exits but were unable to escape the fast-moving inferno.
At least 164 people were injured in the blaze and taken to nearby hospitals. Several were life-flighted to the nearest burn centers in Massachusetts.
Many bodies were still inside The Station nightclub, West Warwick Town Manager Wolfgang Bauer said early Friday. Fire investigators were carefully searching the nightclub's remains to determine how the blaze spread so quickly.
Concertgoers struggle to get out of a doorway as deadly smoke swirls around them.
- Inspecting the site —The fire marshal meets the pyrotechnician at the venue and the pyro get approved in relationship with walls, ceilings, props, people and curtains (must be fire-retardant). Also we look for the smoke alarms in the ceiling as well as the water sprinklers heads and adjust not to be fired right under monitor. We check if the AC vent system has a particle smoke detector to insure no alarms will be triggered.
- Devices must be suitable for the venue — flame projectors shooting 10-foot flames will not be allowed in a venue with 10-foot ceilings. A 10 foot labeled device is marked for the clearance needed. One of each device is tested on the day of the show. You should have a clearance 1 ½ times higher than the device, when angled fallout clearance requirements increase. A 10 ft gerb should have 4-5 ft clearance. and have 15 feet clearance
- There shall be no glowing or flaming particles within 10 ft (3 m) of the audience.
- Air burst shall occur at a minimum height of three times the diameter of the effect. Where the effect is demonstrated, there shall be no burning or glowing particles less than 15 ft (4.6 m) above the floor.
- Warning lights should be used for warning support personnel of the presence of concussion special effects with 25 foot clearance.
- A pyrotechnic device with a 10 ft (3 m) fallout radius should be separated from the audience by a minimum distance of 20 ft (6 am).
- During the show the pyrotechnician is accompanied by fire personnel so the alarms and smoke detectors are downed and are stand-by for the show.
- Public safety — If members of the fire watch detail feel that safety is being compromised, they can stop the show. Depending on the size of the show, a fire truck may also be present and extra fire extinguishers may are required.
- Other safety measures are;
• Safe distance of at least 15 feet between the public and any pyrotechnic device.
• No smoking 25 ft around the devices.
• The proper selected pyro device for the venue and two water-filled fire extinguishers and 2- 2a10bc rated dry extinguishers and a C02 extinguishers available at all times.
- Rehearse the pyro display. "Ask for product demo in the venue the day before or morning of the show" "This will let you know, in a safe environment, how the product will perform in the venue, and if there are any additional changes that need to be made to account for the pyrotechnic effects." If you are using talent, be sure to include them in the pyro rehearsal. "This will allow the artist to be familiar with the effect and to maintain a comfortable distance from the devices while performing.
- Get a copy of the permit issued by the fire department. "Many fully licensed amateur pyrotechicians - such as disc jockeys - claim they do not use enough pyrotechnic devices, and therefore are exempt from obtaining a permit". That is simply untrue, Plus there no such thing as a cold burning gerb sparks in pyro. Gerbs burn at 800% F + and is not cold. The do burn out at full apogee and fall as cold ash. This is what we call Zero Fall Out.
- Leave yourself plenty of time. "Most cities require that request for permits are submitted 15 to 30 days before the event is to take place.
