Passive fire protection is about preventing, slowing or compartmentalizing the spread of fire. This can be achieved through the installation of fire resistant doors, walls, ceilings, floors or a combination of any or all. Torvac Solutions can thoroughly assess your building’s structure and layout to determine if the passive protection components of your building are in proper working order and are being maintained properly.
Basic Passive Fire Passive Fire Protection services include:
• Inspection and testing of smoke curtains
• Fire Seals
• Fire dampers
• Lightweight construction
• Fire & smoke doors
However to make your Passive Fire Protection Strategy most effective as Chris Jelenewicz from the Society of Fire Protection Engineers (SFPE), suggest there are four main areas of passive fire protection that need to be addressed.
Structural Passive Fire Protection
Fire barriers, firewalls, fire partitions, and smoke barriers are all included in compartmentation. Fire barriers include fire-rated walls, floors, and ceilings (often made of concrete, combination wood, gypsum, or masonry). These barriers are used to limit the spread of fire in a building and allow safe egress. Walls extend from a fire-rated floor to the fire-rated ceiling above, and continue into concealed spaces for full protection. In the event of fire these walls when built structurally stable will remain standing.
Other areas of Passive Fire protection that warrant mentioning are cable coating (the application of fire retardants to wire and cable), joint systems (which include changes in direction between fire-separating elements and the spaces surrounded by those elements), and perimeter fire barriers (which deal with the perimeter of the floor and the exterior curtainwall).
While passive fire protection can successfully prevent the spread of fire, it’s important to note that most professionals recommend redundancy in fire protection. In other words, a fire-sprinkler system, alarms and detection systems, and occupant education, in conjunction with passive fire-protection systems, are a safer, more balanced approach to protecting your building and the people inside.
Vigilance is key to maintaining adequate passive fire protection ask the following questions when assessing your passive fire protection strategy:
- Where are there rated walls and floors in your building?
- Are the penetrations and tops of walls sealed?
- If sealed, what tested system design was used for the repair?
- Does the repair match the tested system design detail?
The bottom line: Know what’s going on in your building, and keep your eyes open for any changes in the fire-protection system that reduce it’s performance.
