A useful order: check the intended liquid and marking first. Then think through filling, carrying, transfer and storage from start to finish.

Car

A smaller can that can be secured properly is often more useful than the largest available model. Keep it upright and protect it from sliding, tipping and impact. A legal maximum is not a recommendation to carry that amount.

Camping and motorhomes

Heat, cooking equipment and limited space require extra care. Keep fuel cans clearly separate from water containers and follow the vehicle, campsite and country rules before travel.

Boats and outboards

A spare transport can and a portable outboard fuel tank do different jobs. Secure storage, compatible fuel lines and the engine manufacturer instructions all matter.

Generators

The equipment manual sets fuel type, filling and cool-down procedures. Carbon-monoxide exposure is also a key part of safe generator placement.

Workshops

Commercial use can bring additional duties for labelling, storage and worker protection. Private transport exemptions and domestic garage examples should not be applied to a workplace.

Four-step decision

  1. Confirm the liquid and manufacturer instructions.
  2. Choose the smallest practical capacity.
  3. Check carrying, restraint and transfer.
  4. Review rules for the country, operator and workplace.
Check the actual location: manufacturer instructions and country, harbour, campsite, rental or workplace rules may add further requirements.

Camping & motorhomes

Plan water and fuel containers as separate systems and measure the available storage space.
