Through-life management of LPS dwelling blocks, including their structural assessment for accidental loads and actions

To establish appropriate procedures and processes for the through-life management of an LPS dwelling block, consideration needs to be given to the following (presented as an indicative sequence of activities/issues to be addressed):

1. Hazards and risk environment associated with internal gas explosions, external gas explosions and vehicular impacts to establish threats and

1 INTRODUCTION

The structural hazards to which LPS dwelling blocks are exposed include internal and external gas explosions, fire, as well as the possibility of impacts arising from road vehicles, trains and aircraft. Whilst the probability of the accidental occurrence of these hazards is very small, from a historical perspective overpressure loading and damage arising from an internal gas explosion in an LPS dwelling block has been the type of accidental loading raising the greatest concern.
