What is Short Term Asbestos Exposure

Short term asbestos exposure as a rule occurs when the person is not occupationally involved in asbestos exposure. For example, someone who is renovate their home could be exposed to asbestos fibers from old insulation, roofing and tiles for the duration of renovation which could last from a handful of weeks to a few months.

likely Diseases because of Short Term Asbestos Exposure
Low levels of short term asbestos exposure is not considered a threat to humans and can generally be unseen.

You should be concerned of short term asbestos exposure effects when the duration has been short, but the amount of asbestos fibers inhaled were way over limits. specially short term exposure where renovation of a house is concerned, or during shipbreaking, even the microscopic particles could form a cloud of asbestos fibers and be inhaled by you. This is a cause for concern and you should get medical interest as soon as possible.

The next are the most common diseases that can be caused due to short term, high level inhalation of asbestos fibers.

-- Asbestosis
-- Lung Cancer
-- Mesotheliom

Some proof shows that short-term (acute) oral exposure to asbestos might bring on precursor lesions of colon cancer, and that long-term (chronic) oral exposure might increase the incidence of gastrointestinal tumors.
Most epidemiologic studies to see if cancer incidence is higher than expected in places with high levels of asbestos in drinking water detected increases in cancer deaths or incidence rates at one or more tissue sites (mostly in the gastrointestinal tract).

One time asbestos exposure  for minutes
We were there for about 10 minutes. ... It takes many years of regular asbestos exposure to develop problems from it.

What are the permissible exposure limits for asbestos?
worker exposure to asbestos obligation not exceed
0.1 fiber per cubic centimeter (f/cc) of air, averaged
over an 8-hour work shift. Short-term exposure must
also be limited to not more than 1 f/cc, averaged over
30 minutes. Rotation of employees to achieve
compliance with either permissible exposure limit
(PEL) is prohibited.

Even brief asbestos exposure can be dangerous

  Even though  highest risk of developing mesothelioma comes from regular and prolonged exposure to asbestos, some people have developed the disease after only very brief exposure. Asbestos fibers which lodge in lung tissue and are not expelled continue to damage the tissue as long as they stay there, as the mesothelioma grows slowly and silently. Symptoms may not appear for 15 to 40 years after exposure.
