THIS HOT PLATE MAY NOT BE ALTERED,
MODIFIED OR CHANGED IN ANY WAY.
The State of California enacted the California Safe
drinking water and Toxic Enforcement Act of 1986,
(Prop.65), which “prohibits any person in the course of
doing business from knowingly and intentionally
exposing any individual to a chemical known to the
State of California to cause cancer or reproductive
toxicity without first giving clear and reasonable warning
to such individuals.” The Governor’s Scientific Advisory
Panel added carbon monoxide to the list of hazardous
chemicals known to cause reproductive harm.
In order to establish full compliance with Proposition 65,
we attached a yellow warning label to each gas fired hot
plate manufactured by Keating of Chicago, Inc.
Carbon monoxide would not be present in
concentrations that would pose a “significant risk” to the
consumer when the equipment is installed, operated
and maintained as follows:
Installed under a properly designed operating
exhausting good.
Connected to the type of gas for which the hot plate
is manufactured.
Pressure regulator is installed in the appliance and
adjusted for the manifold pressure marked on the
serial plate.
Adequate air supply to the appliance.
In-line pressure regulator, not supplied by Keating,
must be installed outside the appliance.
The equipment is operated in the manner intended
using the proper utensils.
Keep the equipment clean and have it checked
periodically.
Burner air adjustments, mechanical maintenance and
repairs must be performed by qualified service
personnel.
If the equipment is not installed, operated and
maintained in accordance with the above,
concentrations of carbon monoxide in excess of the
established limits could be present in the kitchen
environment.
ALL PERSONNEL IN THE WORK PLACE WHO MAY
BE SUBJECT TO ANY EXPOSURE OF CARBON
MONOXIDE MUST BE WARNED OF SUCH
POSSIBLE EXPOSURE. THIS WARNING SHOULD BE
CONVEYED IN A MANNER SO THAT IT IS CLEARLY
UNDERSTOOD BY THE EMPLOYEE, AND THE
EMPLOYEE SHOULD BE ASKED IF IN FACT HE OR
SHE UNDERSTANDS THE CORRECT METHOD OF
OPERATION OF THE EQUIPMENT AND THAT A RISK
OF EXPOSURE EXISTS IF THE EQUIPMENT IS
OPERATED IMPROPERLY.
WARNING
IF NOT INSTALLED, OPERATED AND MAINTAINED
IN ACCORDANCE WITH THE MANUFACTURER’S
INSTRUCTIONS, THIS PRODUCT COULD EXPOSE
YOU TO SUBSTANCES IN FUEL OR IN FUEL
COMBUSTION WHICH CAN CAUSE DEATH OR
SERIOUS ILLNESS AND WHICH ARE KNOWN TO
THE STATE OF CALIFORNIA TO CAUSE CANCER,
BIRTH DEFECTS OR OTHER REPRODUCTIVE
HARM.

whether visible or concealed. Do not pay for the freight

on the freight or express receipt and have it signed by
