Pyrotechnics ignited polyurethane foam lining the platform area. NIST investigated rapid fire spread, missing sprinklers, crowd movement and the time available to escape, then tracked changes to model codes and state practice.

Interior finish and ignition
NIST found that pyrotechnics ignited polyurethane foam and fire spread rapidly across the ceiling; smoke appeared at the main entrance in a little over one minute.
Read the primary record ↗Active protection and egress
The venue had no sprinklers. NIST’s test with sprinklers controlled a comparable foam fire, while its investigation found crowding at the main entrance severely impeded escape.

Questions for current buildings, inferred from this case. Check local requirements and the building’s actual condition.
Engineer
Check interior finish, occupancy, sprinklers and egress as one life-safety picture. Which assumptions depend on the actual venue use and local code adoption?
Fire protection contractor
Can finishes, sprinkler condition, exit hardware and any permitted special effects be verified against the operating venue rather than an old fit-out schedule?
Brigade
Does the pre-incident view identify crowd loading, exit routes, interior finish concerns and the venue’s current special-event arrangements?
What has to connect
Approved occupancy and layout; finish evidence; sprinkler and exit inspections; event permissions; drills and corrective actions.
Changes and response
NIST recommended stronger sprinkler requirements, tighter limits on rapidly burning interior finishes and pyrotechnics, and improved egress provisions. Recommendations do not themselves change a local code.
Check current status ↗NIST’s response tracker records a sprinkler requirement for existing nightclubs with occupant loads over 100 in the 2006 NFPA 101 model code and strengthened Rhode Island restrictions on pyrotechnics. Local adoption and applicability must be checked in the jurisdiction concerned.
