Current through Register Vol. 54, No. 28, July 13, 2024
(a)
Generally.
The regulations relating to dust, smoke, gases,
					 fumes, ventilation, sanitation, heat, light, gangways, aisles, safety
					 appliances, washrooms, cleaning rooms, drying and locker accommodations, as
					 specified for iron and steel foundries, shall apply to brass foundries, except
					 that main gangways shall be not less than 4 feet wide and gangways between
					 molds on spill troughs not less than 3 feet wide.
(b)
Platform.
When the crown
					 plate of an upright melting furnace is elevated above the surrounding floor in
					 excess of 12 inches, the furnace shall be equipped with a platform guarded with
					 a standard railing. The platform shall be constructed of metal or other
					 fire-resistive material, extend along the front and sides of the furnace flush
					 with the crown plate, be at least 4 feet in width, and be clear of all
					 obstructions during pouring time. If the platform is elevated above the floor
					 in excess of 12 inches, the lowering from the platform of crucibles containing
					 molten metal shall be by mechanical means.
(c)
Crucibles.
When the
					 combined weight of a crucible, tongs and molten metal exceeds 100 pounds, it
					 shall be removed from the furnace and deposited on the floor by mechanical
					 means.
(d)
Smoke boxes.
When smoke finish is desired on molds made on benches or tubs, smoke
					 boxes which shall effectively trap the smoke shall be used and connected with
					 flues to the outer air.
(e)
Molders.
When molders work side by side, at least 5 feet of
					 space sideways shall be allowed for each employe, and a clear space of 3 feet
					 shall be provided back of each employe.
(f)
Ventilators.
Hoods shall
					 be provided directly above all brass melting furnaces using gas or oil as fuel,
					 which effectively trap all gases and fumes generated in the melting of the
					 metal. The hoods shall be provided with outlet pipes to lead the gases or fumes
					 to the outer air. Ventilators shall be provided over all other furnaces used
					 for melting brass or composition metal to effectively remove the gases above
					 the furnaces.
(g)
Light.
Brass foundries shall be provided with natural light
					 from at least two sides, or from at least one side with skylights in the
					 roof.
(h)
Legs and feet.
Persons removing or handling pots containing molten metal from
					 furnaces shall be provided with protection for the legs and feet.
(i)
Dirt riddling.
Gangway
					 dirt and floor scrapings shall not be riddled in the room where workmen are
					 employed, unless it is dampened so as to prevent the rising of dust.
(j)
Stoves.
When stoves for
					 drying molds are located in the rooms used by workmen they shall be surrounded
					 by a casing of fire-resistive material to the full height of the
					 stove.
(k)
Ceiling.
No brass foundry shall be constructed after November 1, 1915, with a
					 clearance less than 14 feet between the lowest point of the ceiling and the
					 floor, except that where a peak, saw-tooth, monitor or arch roof is
					 constructed, the side walls may be of a minimum height of 12 feet.
