Asbestos (/ æ s ˈ b ɛ s t ə s, æ z-,-t ɒ s / ass-BES-təs, az-, -toss) [1] is a group of naturally occurring, toxic, carcinogenic and fibrous silicate minerals.There are six types, all of which are composed of long and thin fibrous crystals, each fibre (particulate with length substantially greater than width) [2] being composed of many microscopic "fibrils" that can be released into ...
In the late 19th century and early 20th century, asbestos was considered an ideal material for use in the construction industry. It was known to be an excellent fire retardant, to have high electrical resistance, and was inexpensive and easy to use.
In 1943, Johns-Manville suppressed a report confirming the link between asbestos and cancer. During the 1960s, 1970s and 1980s, the company faced thousands of individual and class action lawsuits based on asbestos-related injuries such as asbestosis, lung cancer and malignant mesothelioma. Many new settlements included offering $600 for ...
The recommendation for occupational noise exposure is 85 decibels (dBA) for an 8-hour TWA. For every 3 dB over 85, the exposure time is cut in half. NIOSH reports exposures above this level are considered hazardous. NIOSH uses a hierarchy of control to reduce or remove hazardous noise. [8]
Again, there is no known safe level of exposure to asbestos as it relates to increased risk of mesothelioma. The time from first exposure to onset of the disease, is between 25 and 70 years. [36] It is virtually never less than fifteen years and peaks at 30–40 years. [28] [37] The duration of exposure to asbestos causing mesothelioma can be ...
Asbestos-related diseases are disorders of the lung and pleura caused by the inhalation of asbestos fibres. Asbestos-related diseases include non-malignant disorders such as asbestosis (pulmonary fibrosis due to asbestos), diffuse pleural thickening, pleural plaques, pleural effusion, rounded atelectasis and malignancies such as lung cancer and malignant mesothelioma.

According to OSHA, [11] "there is no 'safe' level of asbestos exposure for any type of asbestos fiber. [12] [13] Asbestos exposures as short in duration as a few days have caused mesothelioma in humans. Every occupational exposure to asbestos can cause injury or disease; every occupational exposure to asbestos contributes to the risk of getting ...
