water supply, fire station location, mutual aid arrangements, and every other character of the response area that this apparatus will be expected to protect.

Growth possibilities of the area should also be considered.

Higher structures and larger buildings may be constructed.

Unprotected areas may be annexed.  After all of these variables are analyzed, then a definite idea can be formed of what size and type of apparatus will do the best task.

A department that has to primarily protect rural areas must be concerned about not ordering a vehicle that is too heavy for the unimproved roads.

Highly maneuverable apparatus are needed in areas with narrow and winding streets.  Areas with large industrial factories may require an engine with 6800 litres per minute (1500 IGPM) capacity and a 2300 litre (500 gallon) water tank, while a rural department may be better served with a 2840 litre per minute (625 IGPM) engine with a 4500 litre (1000 gallon) water tank.

It is best to order by performance specifications as detailed in ULC S515.  They allow the manufacturer greater latitude in selecting the best and most modern components and equipment for the vehicle.  A deviation from this principle may be to designate a diesel engine over gasoline powered, an automatic instead of a manual transmission, a certain model of chassis because of the availability of repair facilities, or other definite preferences.
