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 ...
Silicosis has also been identified as one of many long-term health outcomes for first responders from the terrorist attacks of September 11, 2001, after having been exposed to dust containing high concentrations of respirable crystalline silica, as well as other metals and toxins.
Illustration of Exposure Risk Assessment and Management related to anticipation, recognition, evaluation, control, and confirmation. Occupational hygiene or industrial hygiene (IH) is the anticipation, recognition, evaluation, control, and confirmation (ARECC) of protection from risks associated with exposures to hazards in, or arising from, the workplace that may result in injury, illness ...
During loading and unloading of compost, samplers in the breathing zone detected inspirable dust at 0.74 mg/m3 and respirable dust at 0.42 mg/m3. Samples collected directly from the visible clouds of particles generated by compost agitation contained inspirable dust at 149 mg/m3 and respirable dust at 83 mg/m3 (Weber et al. 1993). [2]
Friability testing is a laboratory technique used by the pharmaceutical industry to test the durability of tablets during transit. This testing involves repeatedly dropping a sample of tablets over a fixed time, using a rotating wheel with a baffle.
The amount of dust produced during handling or processing of a powder can be affected by the nature of the handling process, the ambient humidity, the particle size and water content of the powder, and other factors. To measure dustiness of a particular powder in a replicable way, standardized testing procedures have been created and published. [3]
Particulates or atmospheric particulate matter (see below for other names) are microscopic particles of solid or liquid matter suspended in the air.The term aerosol refers to the particulate/air mixture, as opposed to the particulate matter alone, [1] though it is sometimes defined as a subset of aerosol terminology.
