Fire and Smoke density.

[safetycompliance]

Does anyone know what the Ringman Chart is. Apparently it gives an indication or measure of the density of smoke and fire.

As always thank you for helping.

The Ringelmann Smoke Chart, giving shades of gray by which the density of columns of smoke
rising from stacks may be compared, was developed by Professor Maximilian Ringelmann of Paris.
Ringelmann, born in 1861, was professor of agricultural engineering at l'Institute National
Agronomique and Director de la Station d'Essais de Machines in Paris in 1888, and held those
positions for many years thereafter.
