In order to have fire, you need three things: heat, air, and a fuel. This is called the fire triangle. All three must be present for a fire to sustain itself.
Sand, if enough is used, will either smother a fire by cutting off the air, or cool the fire diminishing the heat.
So sand could work for any fire as long as it is used to remove one item of the fire triangle of heat, air, or fuel.

Sand would be most effective on an oil, chemical, or electrical fire. Using sand would cover a portion of the fire's fuel supply, thus cutting off it's oxygen supply, which would suppress the fire. Using water would be counterproductive on such fires, because, it would either spread the fuel (oil or chemical fire), or increase other dangers (electrical fire).
Sand would be equally effective on any other type of fire, but it is mostly used on fires where it is not possible to use water.

You would use sand on combustible metal fires such as sodium & magnesium.

Any type. There is no liquid in it so it would work on electrical fires and would smother other types.
