I am aware that firefighters declare an exclusion zone (200 m?) around fires which include acetylene cylinders. Would a zone be declared around fires including LPG cylinders (such as are found in caravans) and, if so, how big would it be? LB

The US DoT publishes a A Guidebook for First Responders During the Initial Phase of a Dangerous Goods/ Hazardous Materials Transportation Incident titled "Emergency Response Guidebook" It states that for a small LPG Tank (20 lbs/5 gal 9 kg/19 L ), the safe distance is 160ft/48 m--page 372 It also refers to guide 115 in the guidebook that is common for all Gases - Flammable (Including Refrigerated Liquids) on pages 167 & 168 that highlights for public safety to:- • As an immediate precautionary measure, isolate spill or leak area for at least 100 meters (330 feet) in all directions. • Keep unauthorized personnel away. • Stay upwind. • Many gases are heavier than air and will spread along ground and collect in low or confined areas (sewers, basements, tanks). • Keep out of low areas. http://phmsa.dot.gov/sta...Files/Hazmat/ERG2012.pdf

The exclusion zone set up by the Fire Brigade would depend on a number of factors but look at this document from page 295 onwards may help you answer your question https://www.gov.uk/gover...matt_Manual_COMBINED.pdf

Do a search for Manuals of Firemanship - Hazmat Manual in Dept of Communities & Local Govt. That's about the nearest that you'll get to a definitive answer. Frank Hallett

Interstingly, the Manuals of Firemanship - Hazmat Manual in Dept of Communities & Local Govt refers to the US DoT Emergency Response Guidebook as a key reference/information source on page 139! in Part C Technical considerations
