Engineering controls for nanomaterials are a set of hazard control methods and equipment for workers who interact with nanomaterials. Engineering controls are physical changes to the workplace that isolate workers from hazards, and are considered the most important set of methods for controlling the health and safety hazards of nanomaterials ...
[13]: 9–11 [15] Standard dust control methods such as enclosures for conveyor systems or using a sealed system for bag filling are effective at reducing respirable dust concentrations. [9]: 16–17 Non-ventilation engineering controls can also include devices developed for the pharmaceutical industry, including isolation containment systems.
An N95 respirator is a disposable filtering facepiece respirator or reusable elastomeric respirator filter that meets the U.S. National Institute for Occupational Safety and Health (NIOSH) N95 standard of air filtration, filtering at least 95% of airborne particles that have a mass median aerodynamic diameter of 0.3 micrometers under 42 CFR 84, effective July 10, 1995.
Certified respirators, without exhalation valves, are the recommended form of source control. In hospitals, proper source control protocols are essential. Source control is a strategy for reducing disease transmission by blocking respiratory secretions produced through breathing, speaking, coughing, sneezing or singing. [1]
Lastly, PPE can be an effective method of helping individual workers avoid inhaling harmful aerosols. [26] [27] Due to the varied nature of many workplace dust exposures, there is no single best way to measure and control for aerosols; often, it is required that professional judgement be employed to properly address occupational dust exposures.
Exposure to siliceous dusts in the ceramics industry is reduced by either processing and using the source materials as aqueous suspension or as damp solids, or by the use of dust control measures such as local exhaust ventilation. These have been mandated by legislation, such as The Pottery (Health and Welfare) Special Regulations 1950.
A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas. Designed to handle high-volume dust loads, a dust collector system consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system.
Dust control is another important function of tunnel ventilation. Dust particles generated by drilling and blasting can impair visibility, clog equipment, and harm respiratory health. By directing fresh air through the tunnels, ventilation systems help to reduce dust concentration, improving air quality and visibility.
