Fireproofing

Indoor Commercial Spray Fireproofing on an I-Beam

Spray fireproofing plaster in Canadian highrise building.

"Tamped" Spray Fireproofing on board a ship. The fireproofing consists of a mixture of rockwool fibres with cement and common concrete addmixtures. "Tamping" means that after the spraying, the fresh fibrous spray was flattened down.

Pre-mixed Fireproofing Plaster stored on construction site, ready to spray onto structural steel.

Fireproofing staging: 2 separate units, a gas driven mixer and a feeder pump. A mixed batch is dumped into the feeder pump hopper and then pumped through a hose to the plasterer inside the construction site.

Improper Firestop and Fireproofing interface, August 2000, Cambrian College, Greater Sudbury, Ontario, Canada.

Fireproofing applied at the wrong time, avoiding code compliance with firestops. The steel beam is also a penetrant and its transit through this wall needs to be firestopped properly, as does the HOW joint, none of which happened here, at Cambrian College, Greater Sudbury, Ontario, Canada, August 2000.
