Subsection 724(1)

This subsection requires the end of the duct or brattice cloth at the working face to be as close to the face as possible to achieve the required amounts of air, turbulence and velocity along the working face.

Subsection 724(2)

The referenced CSA Standard ensures materials used in the manufacture of brattice and ducts do not add to the danger of fire and explosion. The survival of ventilating ducts and devices during an emergency can be essential to worker survival.
