A video on cleaning dust from workers' clothing. Occupational dust exposure occurs when small particles are generated at the workplace through the disturbance/agitation of rock/mineral, dry grain, timber, fiber, or other material. When these small particles become suspended in the air, they can pose a risk to the health of those who breath in ...
Exposure to wood dust also occurs through handling of compost containing wood dust. One study measured dust concentrations resulting from handling of compost material consisting of successive layers of chopped leaves, bark, and wood; visible clouds of fine particles were easily generated when the compost material was agitated.

IARC group 1 Carcinogens are substances, chemical mixtures, and exposure circumstances which have been classified as carcinogenic to humans by the International Agency for Research on Cancer (IARC). [1] This category is used when there is sufficient evidence of carcinogenicity in humans.
Wood dust is known to be a human carcinogen, based on sufficient evidence of carcinogenicity from studies in humans. It has been demonstrated through human epidemiologic studies that exposure to wood dust increases the occurrence of cancer of the nose (nasal cavities and paranasal sinuses).
The increased levels of dust and chemicals like asbestos at construction sites leads to workers being exposed. These long term exposures have been linked to the development of lung cancer. [19] Other factors related to construction work can also put the workers at an elevated risk of cancer such as sun exposure.
There’s no simple answer as to why some people are affected and others aren’t. A mold species that might be “toxic” to one person might be tolerated just fine by others.
Amosite and crocidolite are considered the most hazardous asbestos fiber types; [5] however, chrysotile asbestos has also produced tumors in animals and is a recognized cause of asbestosis and malignant mesothelioma in humans, [6] and mesothelioma has been observed in people who were occupationally exposed to chrysotile, family members of the ...
In places such as India, however, there continues to be a high use of friable or dust-based asbestos in compressed asbestos fiber (CAF) gaskets, ropes, cloth, gland packings, millboards, insulation, brake liners, and other products which are being exported without adequate knowledge and information to the other countries. Asbestos use is ...
