Invicta was approached to design and install fire barriers for two transformers and a generator set, which had been in situ for around 10 years. Recent changes in fire safety legislation had led inspectors to advise that T-shaped barriers be fitted, in order to help mitigate the effects of a potential transformer fire or explosion.

Our process begins by establishing a clear understanding of our client’s space saving potential and requirements. This process may take several project design meetings between the client and Invicta Mobile Shelving, and may involve several design drawing revisions to achieve sign-off drawings for manufacture.

The fire barriers would have to be designed not only to be 4-hour fire resistant, but also to resist the effects of local weather conditions. As the Philippines is prone to typhoons, the barriers would have to withstand potential flooding conditions, as well as high wind speeds of up to 45m/s.
These conditions meant that longer anchors and dedicated foundations would be required to achieve the desired performance. The principal challenge would be how to install the required 4.5m long posts, each weighing more than 100 kg, and Durasteel boards at 72 kg each, as there was little space on site for the equipment typically needed to lift the posts, and to fix the boards into position.

Sometimes, rooms within a building require both a high level of fire and blast protection and complete freedom of access. Areas such as equipment rooms and indoor substations can need machinery to be removed entirely, so that it can be properly assessed, maintained or replaced. With a traditional fire and blast protection material such as concrete, this often requires the whole system to be demolished.
Demountable fire barriers allow rooms to be created that fulfil both of these criteria. Durasteel barriers provide up to 240 minute fire protection and comprehensive blast resistance, while also being easy to demount and remove when required. This both reduces the long-term costs of protecting the room, and the cost and disruption of accessing the room for scheduled or unscheduled maintenance.
As well as resisting even extreme hydrocarbon fires and limiting noise up to 56dB, our demountable panel fire barrier systems can be quickly and easily removed, either as prefabricated modules or piece-by-piece. The modular design leaves a completely unobstructed and flush-finish opening in the system, through which equipment and personnel can be freely transported.
This removal process can be completed entirely by hand, and does not require the use of any specialist lifting equipment. For areas such as metro tunnels that are subject to extreme changes in air pressures or frequent vibration, the barriers can also be engineered to resist these pressures and the long-term effects of cyclic loading.
