The steelwork on the mezzanine floor is suitably insulated to prevent it from rapidly heating up in the event of a fire. Steelwork that isn’t securely fastened heats up quickly and can suddenly collapse. The duration of fire protection is specified, such as “1/2, hour” “One hour,” “Two hours,” “Three hours,” “Four hours,” and so on. The duration of fire refers to the period of time that the protected parts remain structurally sound. The criteria for fire protection for different components of buildings are specified in Part B of the Building Regulations. For the finest Mezzanine floors Sydney, go to AW Structures.
The fire protection of construction materials in accordance with rules is a legal requirement that saves lives and property while also allowing the fire department to calculate how long they can safely fight a fire before the risk of damage arises.
The process of adding fire protection to mezzanine floors is referred to as ‘fire rating,’ and a mezzanine floor that has been fitted with fire safety is referred to as ‘fire rated.’
Is It Always Essential To Safeguard Mezzanine Floors From The Fire?
The purpose, size, and extent of the mezzanine level dictate the need for fire protection. Mezzanine flooring that is lower than 10m x 10m in size, occupies less than 50percent of the space of the property in which it is located, is not permanently occupied and only used sometimes (used for storage), and is not permanently occupied and only seldom visited does not require a fire rating.
Mezzanine flooring that is minimal than 20m x 20m in size, holds less than 50percent of the section of the building in which it is located, is not permanently occupied, and is rarely accessed (used for storage) does not need to be fire-rated if it is equipped with appropriate fire detection and warning system.
In Some Fashion, Most Mezzanine Flooring Is Fire-Resistant
The most common technique of fire prevention for mezzanine levels is the use of basic pieces such as insulation, column casings, bulkheads/fascias, a suspended ceiling, and cavity barriers. This method of fire-proofing mezzanine levels is extensively used due to its simplicity of installation and low cost.
A two-part sheet metal shell is coated on the interior with ‘Promalit’ or a similar board for column shells. The sheet metal shell is typically galvanized or white ‘plastisol’ to match the application, but it can also be stainless steel or colored ‘plastisol,’ and the two components are joined with an invisible locking seam that allows them to be joined quickly and cleanly with a few taps from a rubber mallet.
All fire-fighting hardware must be authorized to offer the required layer of safety in the application. For example, any existing suspended ceiling cannot be used beneath a mezzanine floor; the rooftop tile and grid system must be approved to give the required amount of security in steel beam-type mezzanine construction projects, restricting the number of producers who can produce a suitable product.
Conclusion:- It’s usually a good idea to chat to an authorized examiner or building control officer about your specific task before starting construction, which your mezzanine floor contractor would be pleased to assist with.
