One might wonder that why in case of emergencies are we instructed to use staircase? There is a very peculiar reason behind using this strategy to provide a safe passage for the citizen to exit the building. Basically, these walls are constructed using shaft liners that makes them fire resistance. So even if the entire building is on fire, these fire-resistant staircases proffer you with a safe passageway out into an open area to prevent any further mis happenings or fatalities from occurring.
Now you must be in a despicable situation querying that what is shaft liner after all? A shaft liner are specifically, meticulously built flat panels that are designated to be used in lining shafts, lining elevators, stairwells, ventilation shaft, for area walls that needs to be separated from residential units and securing interior structuring application that calls for fire resistance.These panels are constructed concisely using highly non-combustible, formulated gypsum core that is alloyed with glass fibers for embedding additional strength and fire resistance. These panels are covered with a water repelling aqua paper facing back, front and long/ lining of the edges. However, normal shaft liners do not require treatment post finishing, but these aqua formulated guards require painting and other surface modifications. Application of shaft liners:These shaft liners can be used for variety of reasons, which include:
• Stairwell enclosures
• Mechanical stockade for plumbing, electrical, venting service or heating, ventilation and air conditioning (HVAC) operations
• Elevator enclosure
• Manufacturing fire resistant ceilings for corridors
• Separating fire walls from residential areas
Duties of a shaft liner suppliers
While manufacturing and supplying a shaft liner, manufacturers and engineers need to be very vigilante with regards to meeting the requirement of standard methods and practices. These duties include:
The suppliers should make sure that the characteristic of the manufactured panel i.e. shaft liners do meet the expectations and requirements as per customer demand. The normal practice includes producing, manufacturing a dynamically stable, non-combustible, inert gypsum formulated specifically to balance density and amplifying it with glass fibers to meet suitable strength and combustion resistance. Apart from that suppliers should make sure that the panels are asbestos free and certified through GREENGUARD as to safeguard the lives of people dwelling around it.
Standards and codes
Manufactures should be making sure that the panels are produced and constructed based upon the standard codes and regulation as set by the international committees regulating safety and construction. Installation It is advised to the manufacturers and suppliers to install the components as instructed by the listed design. Regular consultations should be made in regard to the GA-600 gypsum association, Fire resistance manual along with the UL directory.
Workers, installers should take precautionary steps by wearing NOSH approved respirators along with safety glasses during cutting, grinding, polishing, rasping or other dust related tasks and activities. These suppliers are of a supreme kind that tend to proffer its users with prolific experience while opting for them to install shaft liners into their desired territorial jurisdiction.
