 In September 2010, a specialist unit, the Hazardous Area Response Team, was established and went live after months of preparation and training.This unit of 32 paramedics was trained to respond to complex or large incidents involving fire, chemicals, biological or nuclear risks, collapsed buildings, cliff or heights, confined spaces, water or firearms incidents.The GWAS unit was one of the last parts of the national scheme to be established; a base was built for the unit in Filton, North Bristol.
