Chap. 260.—An ACT to require the equipment of grinding, polishing and
buffing wheels with suitable devices for the protection of operators and
other persons from dust and refuse thrown off from such wheels; mak-
ing non-compliance a misdemeanor and providing penalty. {H B 88]

Approved March 16, 1918.

1. Be it enacted by the general assembly of Virginia, That all
persons, firms, companies, associations and corporations operating,
or in charge of, a factory, machine shop, or other place or building
where grinding, polishing or buffing wheels are used in the course
of the manufacture or the working on of articles of the baser-
metals, shall provide such wheels with a hood connected by means
of a pipe to an exhaust fan or other suction device in such manner
as to carry away the dust and refuse thrown off by such wheels to
some receptacle so placed as to receive and confine such dust or
refuse, or in such manner as to discharge the same into the open
air outside of such factory or other building; provided, conditions
permit such discharge without injury to persons or property. Every
such hood shall be made of metal or other suitable material and
be of such form and so located in relation to the grinding surface
of the wheel that the dust and refuse therefrom will fall or be
drawn into the hood and be carried off by the pipe attached to it,
and so as to prevent injury to the operator 1f the wheel shall burst.
But connection of such hood with an exhaust fan or other suction
device shall not be required in any of the following cases:

First: When less than five of such wheels are owned or operated
by one person or concern.

Second: When such wheel is provided for only occasional use
by workmen in grinding the tools used by them.

Third: When water is used upon such wheel at the point of
grinding contact.

2. Every hood shall be so constructed as to expose the smallest
portion of the wheel consistent with efficient operation, and its free
edges shall be turned back or faced to prevent injury to the hands
of workmen. Where there is likelihood that the hood may scratch
the work, the edges of the hood should be covered with leather or
other suitable covering.

3. Every such fan or other suction device shall be kept in con-
stant operation while such grinding, polishing or buffing wheels
are 1n operation.

_ 4. Any person who violates or does not comply with the pro-
visions of this act shall be deemed guilty of a misdemeanor, and
upon conviction thereof shall be punished by a fine of not less
than twenty-five dollars nor more than fifty dollars for the first
offense, and by a fine of not less than fifty dollars nor more than
one hundred dollars for each subsequent offense.
