PPE when working with silica containing products. Respiratory protective equipment is not enough to protect your workers from silica dust. Due to the high levels of silica in engineered stone products, a combination of controls are required to protect workers' health including engineering, isolation, work practices, personal protective equipment, worker training and consultation.
As the machine exhales, air travels through the desiccant breather in reverse, or may purge directly to the atmosphere depending on the breather's design. As the breather's silica gel becomes absorbed with moisture, it turns a different color.
So now you're aware of OSHA's more stringent regulations on silica dust exposure, you've tested the job sites in question, you've discovered that the levels of airborne silica dust don't meet the new standard, and now you need to do something about it.There's good news and bad news. The bad news: OSHA penalties are severe and selecting the best remedy can be confusing.
Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula Si O 2, most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of sand.Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as a synthetic product.
When do respirators need to be used and what type should be used? Personal protective equipment, including respirators, should be the last option to prevent a silica exposure. Silica dust should be controlled at the point of origin through the use of vacuum or water controls.
Table 1 lists 18 common construction tasks (and the equipment used) that create high levels of silica dust. The table also describes the engineering controls, work practices, and respiratory protection necessary for each task.

Silica is one of the most common hazards on a worksite, particularly in the construction, oil and gas, manufacturing, and agriculture industries. Silica dust can cause silicosis, a serious and irreversible lung disease. It can also cause lung cancer. Cutting, breaking, crushing, drilling, grinding, or blasting concrete or stone releases the dust.
