As Christmas 2017 approached, social media users began circulating an image of a vintage-looking box labeled “Asbestos: Pure White Fire Proof Snow” and questioning if the packaging really contained artificial snow made out of what is now a widely-recognized carcinogen:

In the early half of the 20th Century, asbestos was widely used as Christmas decor because of its white, fluffy appearance — but that was before the substance was recognized as a major risk factor for an aggressive form of cancer known as mesothelio, as the Asbestos.com website reports:

Asbestos was once marketed as artificial snow and sprinkled on trees and wreaths and ornaments. Although those products have not been produced for many years, the oldest decorations that were passed down from one generation to the next, may still have small amounts of asbestos. The most famous asbestos snow scene was used during the filming of “The Wizard of Oz,” the 1939 classic with Judy Garland that became the most watched film in history. There is a scene in the movie where snow, made from asbestos, falls on Dorothy and her friends, awakening them from a spell cast by the Wicked Witch of the West.

The above displayed above depicts a real item sold to consumers in the mid-20th century. The picture was taken by Tony Rich, an industrial hygienist and amateur photographer who catalogs asbestos images on the photo-sharing platform Flickr using the moniker Asbestos Hunter. Rich, an anti-asbestos activist, originally shot the picture in 2009.

Rich told us he has the actual box in storage and directed us to another photograph that shows the product was manufactured by National Tinsel Manufacturing Company and sold in the late 1940s through the 1950s:

This brand actually contains amphibole asbestos “amosite”, very toxic. Generally speaking, asbestos was used by the tens of millions of tons for nearly over a century and a half in modern history for a wide variety of applications, mostly due to its fire resistance, insulating properties, durability/strength, inertness, could be woven, and was cheap and abundant. Major asbestos manufacturers had large [research and development] programs constantly finding new ways to use asbestos. I believe the most tragic use was in cigarette filters.

Rich told us many people are surprised to learn that, despite its significant link to cancer, asbestos isn’t completely banned in the United States. Aside from raising awareness with his camera as “Asbestos Hunter,” Rich serves on the Prevention Advisory Board for the non-profit Asbestos Disease Awareness Organization (ADAO), on whose blog he wrote in 2015:
