PRECAUTIONS AGAINST COAL DUST
REGULATION 44. GENERAL PROVISIONS
1.
(1) National laws or regulations shall define dangerous
coal dusts as to their explosive qualities in order to determine how
dusty mines are to be classified, and the precautions to be taken
in each case shall depend upon the classification.
(2) This classification shall not be undertaken by the competent
authority without prior consultation with employers' and workers'
representatives.

(3) When coal produces fine and dangerous dust, the tubs
loaded with coal shall be amply wetted with water, or water with
a wetting agent, at the latest when they enter the main haulage

In roads that are regularly used for haulage or travel,
and in main airways, any considerable quantities of dangerous
dust shall be periodically collected and removed.
3.
The manager shall make all such arrangements as are
practicable for the reduction of dust on conveyor roads, and
at conveyor junctions and loading points.
4.
(1) Precautions shall be taken at the surface to prevent
coal dust from entering the downcast shaft in considerable quan-

screening or sorting of coal should be situated within a distance
