IMPORTANT: All manufacturer
products meet current Federal OSHA
Guidelines for safety. California
Proposition 65 warnings are required
for certain products, which are not
covered by the OSHA standards.
California's Proposition 65 requires
w
arnings for products sold in California
that contain, or produce, any of over
600 listed chemicals known to the State
o
f California to cause cancer or birth
defects such as fiberglass insulation,
lead in brass, and combustion products
f
rom natural gas.
All “new equipment” shipped for sale in
California will have labels stating that
the product contains and/or produces
Proposition 65 chemicals. Although we
have not changed our processes,
having the same label on all our
products facilitates manufacturing and
shipping. We cannot always know
“when, or if” products will be sold in the
California market.
You may receive inquiries from
customers about chemicals found in, or
produced by, some of our heating and
air-conditioning equipment, or found in
natural gas used with some of our
products. Listed below are those
chemicals and substances commonly
associated with similar equipment in
our industry and other manufacturers.
• Glass Wool (Fiberglass) Insulation
• Carbon Monoxide (CO)
• Formaldehyde
• Benzene
More details are available at the
Websites for OSHA (Occupational
Safety and Health Administration), at
www.osha.gov
and the State of
California's OEHHA (Office of
Environmental Health Hazard
Assessment), at www.oehha.org.
Consumer education is important since
the chemicals and substances on the
list are found in our daily lives. Most
consumers are aware that products
present safety and health risks, when
improperly used, handled and
maintained.
