How It Works
Anyone may use a grit bin to clear a public path or road, though they are generally not intended for personal use. Typically, a spade or shovel is used to spread a thin layer of grit onto the road surface, covering any snow or ice. The salt lowers the melting point of the snow causing it to melt (see sodium chloride). The grit component improves the friction between a vehicle's tires and the road.
Some grit bins have a small compartment, which could be used for storing a spade or shovel. The one featured in the photograph at the top of the page is filled through the top hatch.

Famous quotes containing the word works:
“The works of women are symbolical.
We sew, sew, prick our fingers, dull our sight,
Producing what? A pair of slippers, sir,
To put on when you’re weary or a stool
To stumble over and vex you ... “curse that stool!”
Or else at best, a cushion, where you lean
And sleep, and dream of something we are not,
But would be for your sake. Alas, alas!
This hurts most, this ... that, after all, we are paid
The worth of our work, perhaps.”
—Elizabeth Barrett Browning (1806–1861)
