Answer 2

Answer:

According to the ILO document, "Diseases caused by physical agents" are as follows: 1) hearing impairment caused by noise, 2) diseases caused by vibration (disorders of muscles, tendons, bones, joints, peripheral blood vessels or peripheral nerves), 3) diseases caused by compressed or decompressed air, 4) diseases caused by ionizing radiations, 5) diseases caused by optical (ultraviolet, visible light, infrared) radiations including laser, and 6) diseases caused by exposure to extreme temperatures. Further, if the exact relationship of the diseases with physical agents could not be define, the principle of all-inclusiveness on the basis of scientific evidence was adapted. Hence, the document included an additional item, 7) diseases caused by other physical agents at work, not mentioned in the preceding items where a direct link was established scientifically, or determined by methods appropriate to national conditions and practice, between the exposure to these physical agents arising from work-related activities and the disease(s) contracted by the worker.
