Prop 65 Warning


Alfresco Heating has always held the health and safety of our customers in the highest regard. Therefore we are doing our best to comply with the California Proposition 65 regulations for the products we sell. Our products are made by different manufacturers, each responsible for labeling their products (and related literature) manufactured from August 30th, 2018 with the applicable Proposition 65 warning(s). Alfresco Heating has a link to this post on all pages of our website to ensure that our customers can become aware of any possible chemical exposure.

The California Office of Environmental Health Hazard Assessment has created this Proposition 65 consumer information site:

What is Prop 65?

According to the Office of Environmental Health Hazard Assessment (OEHHA), California voters, in 1986, approved Proposition 65 -- officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986. The law requires California to publish a list of chemicals known to cause cancer or reproductive toxicity and provide warnings when they knowingly and intentionally cause significant exposures to listed chemicals (a list that currently includes more than 850 chemicals). Proposition 65 does not ban or restrict the sale of chemicals on the list. The warnings are intended to help Californians make informed decisions about their exposures to these chemicals from the products they use and the places they go.

In 2013, Gov. Edmund G. Brown Jr. proposed reforms to strengthen Proposition 65. The Governor called for changes to “require more useful information to the public on what they are being exposed to and how they can protect themselves.” He added, “This is an effort to improve the law so it can do what it was intended to do – protect Californians from harmful chemicals.”

New OEHHA regulations were therefore adopted in August 2016 and took full effect in August 2018. These updated change the safe harbor warnings which are deemed to comply with the law in several important ways.
The new warning system has several main goals. These include:

  • Making warnings more meaningful and useful for the public
  • Reducing “over-warning” in which businesses provide unnecessary warnings
  • Giving businesses clearer guidelines on how and where to provide warnings
