Industrial risks and land use planning. Study of blast window resistance

Technological Risk Prevention Planning (PPRT) is a French tool for managing land-use planning near upper-tier SEVESO industrial facilities. Its purpose is to protect the population against industrial hazards. Risk limitation measures may include for example window reinforcement for new or existing blast risk exposed buildings. In order to better define technical guidelines for window reinforcement, INERIS developed an innovative experimental device. INERIS has studied window behaviour and has evaluated blast capacity of different kinds of glass panels (monolithic or insulated glasses with or without anti-explosion film, laminated glasses...), mobile frames or window locking or anchorage systems. Results show that all window components have to be considered to improve safety.
