The claim that “the onset of asbestosis in a normal working life should not develop if (exposure is maintained within maximum limits)” was cited by critics as evidence of insufficient assurance. Given the time lag which exists between exposure and the diagnosis of asbestos-related diseases, it was unlikely that disease would be diagnosed in a normal working lifetime irrespective of levels of exposure.
Despite these criticism, the recommended guidelines were incorporated into the working practice of the British Builders Federation. As a result, it is possible that workers who have been exposed to asbestos may continue to die of asbestos-induced tumors well into 21st century.
