FRUs are equipped with heavy lifting, winching, cutting and pulling tools, floodlighting, longer duration breathing apparatus (vital for rescuing people from tunnels deep underground) and portable generators and other specialised equipment. FRU crews are specially trained and equipped to handle complex rescues, including those from road and rail accidents, water, mud and ice, urban search and rescue incidents such as collapsed buildings, chemical spills and difficult rescues at height. These vehicles would later play a major role in the July 7th 2005 London bombings.
Nine of the Brigade’s existing fleet of Fire Rescue units were mobilised to the London bombings of 7 July 2005 and since then the LFB has upped its number of FRUs from 10 (including one reserve) to 16, but not before first cutting the FRU's from ten to nine. A study took place on behalf of the politicians and all the results were produced to prove that the LFB could afford to reduce the FRU's by one, this would save money, £900,000.00 a year, bloody politicians, at the time the protests of the people on the front line were ignored.
