AOVs
Being blocked by external scaffold
Inform method statements
AOVs
Being forced open by occupiers/smokers
Education of occupiers
AOVs
Rooflight used to access roof
Upgrade actuator
Fire Door
Closer disconnected
Record torque and speed of closing
Fire Door
Painted or warning sticker removed
Education of occupiers
Fire Door
New flooring fitted, creating gap
Training, inspection and sign-off
Sprinkler Systems
Compressed air being used to flush water but creating oxidisation and leaks
Standardised tasks and training
Fire Door
New door bell fitted, compromising penetration
Education of occupiers
Compartmentation
30 min foam used on 60 min door or damper
Training, inspection and sign-off
Compartmentation
Water ingress damaging fire integrity
Inspection and better asset records
Smoke control
Smoke seal on door damaged when easing a non-closing fire door
Training, inspection and sign-off
Cladding
Fire stopping deteriorated due to water ingress
Fix leak and replace fire stopping
Penetration Seals
Collar installed within batt then angle used to ‘support’ it but using drywall or wood screws and threaded rod with bolts unlikely to have come from a tested solution
Penetration Seals
Pipe fouling the wall, pipe in first
Penetration Seals
Inappropriate use of ‘fire rated foam’
Penetration Seals
Inappropriate use of ‘fire rated foam’
Penetration Seals
Firestop services at floor level, through installed services
Penetration Seals
Pipe chase with no closers installed before boxing in
Penetration Seals
Edges not coated on top level, firestop products unlikely to be tested for services, not sealed correctly to prevent smoke etc
Penetration Seals
Dry board joints and inappropriately sealed services
Penetration Seals
Dry board joints and inappropriately sealed services, no seal within tray
Penetration Seals
Dry board joints, likely to be combustible insulation passing through without proper sealing /closer
Penetration Seals
No sealing of services,
Penetration Seals
No sealing of services, batt stops and then suspended ceiling, batt cannot compression fit against suspended ceiling
Penetration Seals
Dry board joints, no closer and exposed metal
Penetration Seals
Boards have fallen out therefore indicative of dry installation, mastic used as a mortar to secure in place
Penetration Seals
Close proximity of other elements of structure limit access for air seal / fire stop
Penetration Seals
Access to wallhead after services installed
Penetration Seals
Interface of wall, deck and partition leaving void along length of block wall
Penetration Seals
Inappropriate sealing of partition wall
Penetration Seals
Riser still to be sealed at floor level,
Penetration Seals
Inside of riser, damaged walls, not taped and filled, timber penetrations unprotected, no access to seal, combustible soffit of riser, plastic pipe passing through wall with no closer
Penetration Seals
Out of line damper, gaps in wall
Compartmentation
Poorly installed and possibly wrong product
Check manufacturer installation method
Compartmentation
Failed compartmentation
Inappropriate materials
Replace with fire rated material appropriate for location (movement, dimensions, etc)
Dry Lining and Fire Walls
New installation
Core hole then firestop to prevent facing board from breaking
Compartmentation
Cables
Void created for service too large and next to ceiling trim
Reduce core sizes – reflects fire stop test solutions
