I"ve got three jerry cans in the garage (for use in car in avatar). Must fill "em up. Highly illegal of course to have that much petrol at home. But then, with two cars in the driveway with >40litre tanks each, one wonders why there is such a low limit.
The tanks in your car are probably crash-protected (unless a certain USA-made Pickup truck) and in the UK subject to annual inspection -the MoT – ( 2nd in a week for me, tomorrow, but better than 2 on the same day a few years ago 8-( ). Access is probably restricted to a keyholder.
Jerry cans (I assume the minister meant the smaller plastic types, but used the equivalent of "Hoover" or "Biro" are unchecked and may have little security…. and be close to buildings with sleeping occupants….??…
Here is a definition (UK/EU applicable)
A jerrican is defined within Chapter 1.2 of the 2011 ADR as a metal or plastics packaging of rectangular or polygonal cross-section with one or more orifices , a definition which includes the traditional jerrycan but which also covers a wide range of other packagings.
The Petroleum Spirit (Motor Vehicles etc.) Regulations 1929 and the Petroleum Spirit (Plastic Containers) Regulations 1982 limit the amount of petrol that can be kept in a domestic garage or within six metres of a building (e.g. most domestic driveways). The limit is a maximum of two suitable metal containers each of a maximum capacity of ten litres or two plastic containers (which have to be of an approved design) each of a maximum capacity of five litres. These limits also apply to any containers kept in a vehicle parked in the garage or on the driveway (but not to the internal fuel tank of the vehicle). Under no circumstances should the petrol containers be stored in the home itself.
Other lower limits may apply to what you can carry in your vehicle: For example, on ferries, we had to stop carrying a 10l diesel spare, as the limit is 5litres. Gas cylinders /cartidges (not on caravans - which are just turned off) having to be handed to the Purser and collected on departure, etc
