When was asbestos mostly used

From 31 December , the total ban on manufacture, use, reuse, import, transport, storage or sale of all forms of asbestos came into force. Many houses built before therefore contain asbestos cement materials, especially in the eaves, internal and external wall cladding, ceilings particularly in wet areas such as bathrooms and laundries and fences.

Asbestos today The regulations described above and other actions, coupled with widespread public concern about the hazards of asbestos, have resulted in a significant annual decline in U. These materials may release asbestos fibers if damaged, repaired, or removed improperly. Sanding tiles can release fibers. So may scraping or sanding the backing of sheet flooring during removal.

Repairing or removing appliances may release asbestos fibers. So may cutting, tearing, sanding, drilling, or sawing insulation. Worn seals can release asbestos fibers during use. Loose, crumbly, or water-damaged material may release fibers. So will sanding, drilling, or scraping the material. Sanding, scraping, or drilling these surfaces may release asbestos.

These products are not likely to release asbestos fibers unless sawed, dilled, or cut. Where to Look for Asbestos Hazards in the Home Some roofing and siding shingles are made of asbestos cement. Houses built between and may have asbestos as insulation. Asbestos may be present in textured paint and in patching compounds used on wall and ceiling joints. Their use was banned in Artificial ashes and embers sold for use in gas-fired fireplaces may contain asbestos.

The early s also saw the founding of large asbestos industries in Scotland, Germany and England. Italy had been mining tremolite asbestos for decades. By the early s, anthophyllite asbestos was mined in Finland. Amosite brown asbestos was discovered in Transvaal, South Africa.

Chrysotile from the mines of Swaziland and Zimbabwe was mined and marketed around the world. Before the late s, asbestos mining was not mechanized. The heavy work of chipping away rock and extracting the asbestos for further processing was performed manually. Horses and drays were utilized for transporting the mined product. But once the commercial applications for asbestos were realized and demand grew, asbestos mining became industrialized.

Its manpower multiplied by steam-driven machinery and new mining methods. By the early s, asbestos production had grown worldwide to more than 30, tons annually. Children and women were added to the asbestos industry workforce, preparing, carding and spinning the raw fibers, while men toiled in the mines.

The uses of asbestos expanded just as rapidly as its manufacture. Henry Ward Johns in founded the H. Johns Manufacturing Company in lower Manhattan when he was He sold new, fireproof roofing material made of burlap, asbestos, tar and other ingredients.

The anthophyllite asbestos he used came from a quarry in nearby Staten Island. His firm merged with the Manville Covering Company in Johns Manville became the largest manufacturing enterprise that used asbestos in the U.

In , the first asbestos brake linings for new horseless carriages were made by Ferodo, a British company. Three years later, in Germany, the first patent was issued for the manufacture of asbestos cement sheets.

High-pressure asbestos gaskets were turned out in by Klinger in Austria. The first asbestos pipes were developed in Italy in Mining in the U. As early as , an Austrian doctor attributed pulmonary troubles in one of his patients to the inhalation of asbestos dust.

In , the first documented death of an asbestos worker from pulmonary failure was recorded by Dr. The autopsy of the year-old victim revealed large amounts of asbestos fibers in his lungs. And as early as , insurance companies in the U. Despite consistent health warnings, asbestos mining and manufacturing was an engine that could not be stopped.

In , world production exceeded , metric tons, more than three times the total in Asbestos products filled that need. The start of World War II revived that growth. Environmental Protection Agency EPA , more than 30 million tons of asbestos were used between and Some of these past uses are still in materials and products people may come into contact with today.

There is less asbestos risk in newer homes. Although asbestos is not fully banned in the United States, newer homes typically were not built with asbestos-containing materials. Homes built after are less likely to contain asbestos. However, stockpiles of asbestos-containing materials may have been used into the s. Asbestos-containing materials may be found in all areas of the home. From the s through the s, asbestos was included in building materials.

It was also incorporated into a number of asbestos-containing vinyl products. The mineral was popular because of its durability and resistance to heat and chemicals. The varied uses of asbestos before the s put many in danger of asbestos exposure in their homes. It is not possible to identify asbestos-containing materials with the naked eye. However, there are signs of asbestos homeowners can look for. These clues may hint toward the presence of the mineral in certain products.

For example, the older a home is, the more likely asbestos materials were used during its construction. Homes built before should be assumed to contain the mineral somewhere. Newer homes are less likely to contain asbestos products.

Textured paint used on walls and ceilings often contained asbestos. Popcorn ceilings were popular between and the early s. Homeowners should assume all popcorn ceilings from this period contain asbestos. Dimpling materials in the home should be tested by an asbestos professional. Without testing done by an asbestos professional, it can be very difficult to identify asbestos products at home. However, it may be possible to identify asbestos-containing materials through packaging.

Homeowners may be able to safely inspect packages of leftover home construction materials for labels signifying the products contain asbestos. For example, spare boxes of vinyl floor tiles may have a stamp on the box or the back of the tiles that states they contain asbestos.

A date included on the packaging may also indicate that they were manufactured during the height of asbestos use s — s. However, handling the tiles may carry exposure risk. Homeowners should only inspect the outside of the packaging for a label.

If there are no packages, it is best to assume any flooring or other construction materials installed before contain the mineral. Homeowners should treat these materials with caution. While visual clues like labels can suggest the presence of asbestos in the home, it is not a fool-proof method to identify asbestos. To continue the earlier example, vinyl floor tiles have a high likelihood of containing the mineral. However, these products came in a variety of shapes and sizes, and not all used asbestos in their production.
