Concerns about cancer-causing asbestos have lead to the temporary closure of two Orange County elementary schools as district officials release new test results this morning.

After a school board meeting last Tuesday night in Huntington Beach they have decided to close all 11 schools in the district to test for asbestos. All the schools will closed until testing is completed.

The school district will test every room in its 11 schools for asbestos after questions were raised about whether students were exposed to carcinogenic dust during construction projects earlier this school year.

Local news media sources report that two schools, Oak View Elementary and Hope View Elementary, were closed following asbestos removal last Saturday.

Ocean View School District officials say they are investigating whether contractors violated protocol by removing asbestos on or after the first day of school

The closures left parents furious and forced more than 1,600 students to be bused to classrooms in eight different school districts across Orange County.

But the coastal Ocean View School District had a shot of good news when recent tests showed that all but three campuses were deemed not to have an unsafe level of asbestos in classrooms.

Tests showed that most of the schools had an “insignificant” level of asbestos in the air and that, even in classrooms where trace levels of asbestos were found, measurements were far below federal standards for a hazard and would not pose a risk to staff or students.



Asbestos (pronounced /æsˈbɛstəs/ or /æzˈbɛstəs/) is a set of six naturally occurring silicate minerals[1] which all have in common their eponymous asbestiform habit: long (roughly 1:20 aspect ratio), thin fibrous crystals. They are commonly known by their colors, as “blue asbestos”, “brown asbestos”, “white asbestos”, and so on.

Asbestos mining began more than 4,000 years ago, but did not start large-scale until the end of the 19th century when manufacturers and builders used asbestos because of its desirable physical properties:[1] sound absorption, average tensile strength, its resistance to fire, heat, electrical and chemical damage, and affordability. It was used in such applications as electrical insulation for hotplate wiring and in building insulation. When asbestos is used for its resistance to fire or heat, the fibers are often mixed with cement or woven into fabric or mats. These desirable properties made asbestos a very widely used material, and its use continued to grow throughout most of the 20th century until the carcinogenic (cancer-causing) effects of asbestos dust caused its effective demise as a mainstream construction and fireproofing material in most countries. However around 2 million tons of Asbestos are still mined per year as of 2009, mainly in Russia (50%), China, Brazil, Kazakhstan and Canada (9% to 14% each).

It is now known that prolonged inhalation of asbestos fibers can cause serious and fatal illnesses including malignant lung cancer, mesothelioma, and asbestosis (a type of pneumoconiosis).[2][3] Health issues related to asbestos exposure can be found in records dating back to Roman times. By the beginning of the 20th century concerns were beginning to be raised, which escalated in severity during the 1920s and 1930s. By the 1980s and 1990s asbestos trade and use started to become banned outright, phased out, or heavily restricted in an increasing number of countries.

The severity of asbestos-related diseases, the material’s extremely widespread use in many areas of life, its continuing long term use after harmful health effects were known or suspected, and fact that asbestos-related diseases can emerge decades after exposure ceases, have resulted in asbestos litigation becoming the longest, most expensive mass tort in U.S. history and a significant legal issue in many other countries. Asbestos-related liability also remains an ongoing concern for many manufacturers, insurers and reinsurers.
