Flour dust. Flour dust is a hazardous substance. Workers in baking-related jobs may inhale flour dust when it becomes airborne. The dust can irritate the respiratory tract and lead to occupational asthma, also known as baker's asthma. The health problems can develop over 30 years. Flour dust can also cause an explosion.

Occupational Dust Exposure Of Stone Grinding Mill Worker Silicosis: An Industry Guide to Awareness and Prevention . Jun 27, 2017 · For hundreds of years, silicosis has been a serious occupational health issue for workers in mining, quarrying, stone cutting, stone grinding, and other occupations where crystalline silica dust is generated. ...
Because of work-exposure to silica dust, silicosis is an occupational hazard to mining, sandblasting, quarry, ceramics and foundry workers, as well as grinders, stone cutters, stone countertops, refractory brick workers, tombstone workers, workers in the oil and gas industry, pottery workers, fiberglass manufacturing, glass manufacturing, flint ...
However, cutting, grinding, chipping, sanding, drilling, and polishing natural and manufactured stone products can release hazardous levels of very small, crystalline silica dust particles into the air that workers breathe. Working with ground quartz in the countertop manufacturing industry can also expose workers to dangerous silica dust.
merit, as it would reduce the risk of workers developing disease, allow workers to use a lower level of respiratory protection, protect workers during short duration work episodes, reduce exposure to nearby workers, and reduce clean-up associated dust exposures.

That cloud of dust you see when a worker cuts or grinds concrete, brick, or stone is not just harmless dust... It contains crystalline silica... and IT CAN KILL. Most crystalline silica is in the form of quartz. Common sand is almost quartz. Fine particles created by cutting and grinding …
Apr 01, 2002· The time-weighted average concentration of silica dust in 69% of the samples exceeded the current recommended threshold limit value of 0.05 mg/m 3, indicating a strong need to devise methods for controlling workers' exposure to crystalline silica dust during concrete finishing activities.

design was employed on 127 male nonsmoker cobblestone paving workers and 194 matched employed office workers as a reference in order to assess changes in pulmonary function related to dust exposure among cobblestone road paving workers of Jimma zone, Ethiopia.
Patients and methods. This study was carried out at flour mills in Sohag Governorate. Two hundred male workers with current exposure to flour dust and two hundred non-exposed male as a control group were interviewed and self designed study questionnaire was administered to them and the parameters of their pulmonary function were measured.
dust exposure of stone grinding mill workers assessment. SUAMG Machinery is professional mineral processing equipment manufacturer in the world, not our equipment has the excellent quality, but also our product service is very thorough. made in china marble stone machine grinder to crash into dust.
What activities in stone fabrication expose workers to silica dust? Activities such as grinding, cutting, routing, drilling, chipping, or polishing on granite and other stone materials containing crystalline silica can create airborne dust and the potential for health hazards to workers.
Jun 01, 2003· Conclusions: Plywood mill workers are exposed to inhalable dust, bacterial endotoxin, abietic acid, terpenes and formaldehyde, and they appear to have an increased risk of developing work-related respiratory symptoms. These symptoms may be due to formaldehyde exposure, although a potential causal role for other exposures cannot be excluded.
The particles are "inorganic" or "organic," depending on the source of the dust. Inorganic dusts can come from grinding metals or minerals such as rock or soil. Examples of inorganic dusts are silica, asbestos, and coal. Organic dusts originate from plants or animals. An example of organic dust is dust that arises from handling grain.
Silica dust in the workplace At least 600-900 people die each year from work-related disease in New Zealand. Exposure to a form of silica dust – respirable crystalline silica (RCS) – is dangerous and can cause serious lung disease.
Workers may be exposed to crystalline silica while cutting, grinding, sanding and polishing stone bench tops and during the installation process. Generally exposure to RCS occurs during manufacture of the stone benchtop rather than during installation due to less cuts and fabrication taking place.
Stone dust is a by-product of crushed rocks; as a multipurpose building material it provides compact results. Despite its many benefits to the construction industry, it comes with a number of health risks.
The use of the "Agra" (80% silica content) and the buff stone (81% silica) for grinding and regular chiseling by the workers in order to maintain the rough texture of the surface leads to silica dust exposure [Figure 1]. In India, silicosis has been made a notifiable disease under the Factories Act 1948 and Mines act 1952.
Silicosis is an ancient occupational illness reported in silica mill workers, agate stone workers, slate pen workers and mining industry. ... Past history of occupational exposure to silica dust other than flour mill. ... daily working hours at the mill, number of years at the mill, type of grinding stone used, frequency of chiseling of the ...
Rankin et al. (1986) concluded that these findings "suggest that chronic grain dust exposure may result in chronic obstructive pulmonary disease" (p. 26). Rankin et al.'s (1986) study also included a work-shift study in which 248 grain workers and 192 city workers were sampled for grain dust exposure …
fact sheet describes dust control that can be used to minimize the amount of airborne dust when using handheld grinders for uses other than mortar removal as listed in Table 1 of the Respirable Crystalline Silica Standard for Construction, 29 CFR 1926.1153. Engineering Control Method: Water applied continuously to the grinding wheel OR Vacuum Dust
