Requirement During construction of a new project site safety officials at a major oil refinery decided they needed a range of portable buildings to protect their workforce in areas of potential explosion. Elliott had for several years, provided a range of portable buildings used for up to 1000 workers during construction work at the site. Although staff had been completely satisfied with the quality of the buildings provided by Elliott there were concerns that they would not withstand adequately the pressure an explosion would create. Elliott staff worked closely with an industry specialist to design Anti-Blast portable buildings not only of the desired quality but also to provide the necessary protection needed for such a potentially explosive site. Following approval by safety officials at the oil refinery over 500 Anti-Blast portable buildings have been specifically manufactured to rigorous standards to withstand 100 Mba free eld over pressure with 200 Mba reflective overpressure on any face. Anti-Blast portable buildings are providing workers with temporary offices, canteens, changing rooms, toilets and showers.
