(a)
Melting pot.
The melting
					 pot of the buckle casting machine shall be provided with a hood connected with
					 an efficient air exhaust.
(b)
Lead dust.
The work of stripping the stacks shall be so
					 conducted, and such adequate devices provided and maintained by the employer as
					 to protect the employe as much as possible from lead dust.
(c)
Other equipment.
The
					 employer shall equip the crane bucket, box, barrel, car or other receptacle
					 into which the corroded buckles are dumped, with a hood or other tight-fitting

					 efficient dust collecting system. Such system shall be regulated by the
					 discharge of air from a fan, pump or other apparatus through an enclosed cloth
					 dust collector, having an area of not less than one square foot of cloth to
					 every cubic foot of air passing through it per minute. If this cloth dust
					 collector is not of the portable type, it shall be placed in a separate room or
					 in a permanent dust house equipped with baffles or such other appartus to
					 adequately take care of all dust which it may receive. The dust collector shall
					 be provided with adequate means, so that the dust can be removed by an employe
					 or employes who are outside the room or dust house, and no employe shall be
					 required or allowed to enter such room or dust house except for the making of
					 essential repairs, and then only when the dust-collecting machinery is not in
					 operation.

Discharge point.
The dump, hopper, chute or other point at which the corroded buckles
