Silica dust is harmful when inhaled into your lungs. As it is 100 times smaller than a grain of sand, you can be breathing it in without knowing. Exposure to silica dust can lead to the development of lung cancer, silicosis (an irreversible scarring and stiffening of the lungs), kidney disease and chronic obstructive pulmonary disease.

Stop concrete dusting and prevent health risks with silica dust prevention measures and reliable concrete cutting products. Learn more!
Engineered stone products can contain up to 97 per cent silica. The high amount of silica means that there is a very high risk of workers developing breathing problems and silicosis if they breathe in dust made from these products. The vast majority of silicosis cases identified in recent years are in engineered stone workers.
Silica dust is generated by mining activities, including cutting, sanding, drilling, crushing, grinding, sawing, scraping, jackhammering, excavating, and hauling materials that contain silica. Silica dust also mixes with other dusts created during mining, such as coal dust, to create increased risk of illness and death.
The Center for Construction Research and Training (CPWR) offers a one-stop online resource with information and tools to help identify silica hazards, understand the health …
Best Practices for Dust Control in Metal/Nonmetal Mining – Mineral Processing Operations – Local Exhaust Ventilation Systems
By following the requirements specified in OSHA's Table 1 fully and completely, you will not be required to do air monitoring and will be assumed to be below the permissible exposure limit. Table 1 silica resources for compliance.
Silica dust is produced when polishing and grinding concrete, and also when cutting concrete or masonry, or drilling, crushing and cutting some types of fibre-cement board. It can also be produced when cutting or grinding engineered kitchen benchtops that have a high silica content. Breathing in fine silica dust over prolonged …
The new code is Australia's first silica dust code of practice for the construction industry. It applies to all construction work as well as the manufacturing of materials such as bricks, blocks, tiles, mortar and concrete.
breaking, crushing, grinding or milling silica-containing material such as concrete, aggregate or mortar. drilling, cutting, chiselling or sanding silica-containing material. dealing with cement. moving earth, for example excavating, mining, quarrying or tunnelling. abrasive blasting or sandblasting.
HA 29 CFR 1926.1153Other resourcesKEY POINTS FROM THE NEW SILICA DUST STANDARDThe new standard requires a more stringent "permissible exposure limit", …
Silica has been classified as a human lung carcinogen and inhaling silica dust can lead to silicosis, a lung disease, which can be However, in our industry, grinding and crushing can result in an airborne dust, which can be inhaled.
Use local exhaust ventilation to remove dust at the point it is produced. Ensure tools have on-tool extraction. Wet down the work to keep dust levels lower. Wear suitable respiratory protective equipment that fits properly. Clean up correctly – no dry sweeping of silica containing materials.
Silica: Controlling Silica Dust in Construction - Heavy Equipment and Utility Vehicles Used for Grading and Excavating Tasks Fact Sheet
Best Practices for Dust Control in Metal/Nonmetal Mining – Mineral Processing Operations – Crushing & Grinding
Crystalline silica dust can harm workers, so it is vital to have a safety management plan in place. Learn about safety while working with engineered stones.
More than a dozen fact sheets recently published or revised by OSHA describe controls that can be used to minimize airborne dust and limit exposures to silica in the construction industry. Each fact sheet addresses controls for a specific type of construction equipment referenced in Table 1 of OSHA's recent final rule on respirable crystalline silica, …
CPWR's Exposure Control Database can help you anticipate and control worker exposures to silica, welding fumes, lead, and noise. This free online tool allows users to enter a construction task, proposed controls, and other variables and obtain a predicted exposure level based on exposure data from trusted sources.
What does create a good amount of the troublesome fugitive fines is equipment driving on top of larger particles, such as sand and powders and crushing them into dust.
Using heavy equipment and utility vehicles for earthmoving tasks such as grading and excavating does not in most cases generate hazardous levels of respirable crystalline silica dust. However, in dry conditions hazardous exposures can occur. This fact sheet describes methods to minimize the amount of airborne dust when using heavy equipment or …
It only takes a very small amount of the very fine respirable silica dust to create a health hazard. Recognizing that very small, respirable silica particles are hazardous, OSHA …
OSHA's Silica Rule or Permissible Exposure Limit (PEL) was finalized and implemented for the construction industry in 2017. The rule goes into effect in June 2018 for "General Industry" which ...
This guidance provides information on identifying hazards and controlling the risks of exposure to dust containing crystalline silica in the extractive industry.
This guidance is to provide information on hazard identification and the control of risks of exposure to crystalline silica dust in construction.
The main industries where occupational exposure to crystalline silica dust occurs include construction, mining, quarrying and stone crushing operations, foundries, brick making, concrete, ceramics and glass [ 4 ].
Identifying hazards and controlling the risks of exposure to dust containing crystalline silica in the stonemasonry industry.
Crystalline silica is a mineral commonly found in sand, stone, rock, concrete, brick, block or mortar. Workers are exposed to crystalline silica dust in many daily operations like cutting, sawing, drilling or crushing components that contain crystalline silica. Industries affected by this new rule include construction, general industry, maritime and hydraulic fracturing.
Stone crushing has long been associated with exposure to airborne crystalline silica dust to both workers and those residing in close proximity to these operations. Water spray …
1926.1153 (a) Scope and application. This section applies to all occupational exposures to respirable crystalline silica in construction work, except where employee exposure will remain below 25 micrograms per cubic meter of air (25 μg/m 3) as an 8-hour time-weighted average (TWA) under any foreseeable conditions. 1926.1153 (b) Definitions.
Silica dust can originate from various sources across different industries and work environments. Silica-containing products can emit dust particles during cutting, crushing, drilling, polishing, sawing, or grinding. Such minute particles can penetrate the lungs and lead to various health problems, including silicosis.
This Code provides practical guidance for persons conducting a business or undertaking on how to manage risks associated with respirable crystalline silica (RCS) exposure in construction work and manufacturing of construction elements.
