AUST – Essential Property Services advise building owners and managers of the need to ensure that their consultants, contractors or tenants’ contractors know when ‘fire-rated wiring’, an essential safety measure, is required.  This problem seems to arise when a tenant instigates a new fit out (building upgrade) and finds out the existing cabling does not comply, usually without obtaining a building permit.  A request for the building owner to upgrade the non-compliant cabling at their cost  is then made, causing all stakeholders to study the lease conditions, sometimes heading into a legal confrontation.

A number of tenants can experience significant inconvenience through contractors installing incorrect cabling for essential safety measure items, when rewiring has had to occur in adjoining tenancy areas that are not associated with the tenant undertaking the works.                                                                                                                                                                                                                     Tasmanian Building Permit                                           Fire rated cables are designed to continue functioning during a fire for a specified period of time. This allows for the safe fire evacuation of a building through the cabling’s ability to support essential safety measures such as smoke control measures, emergency lighting, occupant warning systems/SSIS systems and so forth. In essence, fire rated cables are required to be able to burn in a manner that ensures continuity of power to essential safety measures during a fire.                                                                                                                                                                                                              Fire rated cables do not work alone.  The AS/NZS 3013: 2005 Electrical installations – Classification of the fire and mechanical performance of wiring elements, requires that all items comprising a fire rated cabling system operating in the fire rated zone must be assessed and passed as a system. In other words, contractors must ensure other ancillary components that may be used in the installation, including stopping methods, fasteners, saddlers, ladders, and cable trays also comply with the standard, and would be incorporated into the essential safety measures.

Some examples for fire rated wiring in new or altered works are:
