Two engineered stone fabrication workers died in 2018 in California from severe silicosis at the ages of 36 and 38. According to CDPH, both worked at a stone countertop fabrication company performing tasks such as polishing, dry cutting, and grinding slabs of engineered stone, which can contain more than 90 percent crystalline silica.

Jan 08, 2018 Understanding The Dangers Of Stone Dust. Explore our stone worker PPE . Those who work with stone can experience serious disease and ill health as a result of breathing in dust. Respirable Crystalline Silica (RCS) is found in stone dust and causes silicosis, cancer and chronic obstructive pulmonary disease (COPD).

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.

Dec 08, 2015 Is exposure to airborne concrete, stone, brick, or granite dust hazardous to my health? Posted December 8, 2015 by Jim Orr. Federal and state authorities have passed laws requiring workers who cut or grind materials such as concrete, brick, stone, or granite to wear respirators or other devices designed to protect them from breathing in these materials.

Creating a work environment that gives workers the ability to capture and filter grinding and deburring dust at the source, is the key to safe prevention. The degree of risk to workers is determined by factors such as the length of exposure, the type of material being worked with, the type of protection and the effectiveness of that protection.

Read MoreThis study surveyed wood dust exposure levels and pulmonary hazards among wood mill workers. Dust concentrations as measured by six-stage cascade impactors were high in work areas of grinding and screening. Total dust concentrations for these dusty activities ranged from 4.4 to 22.4 mg/m3, and the respirable proportions were between 2.4% and 50.2%.

The exposure standard for crystalline silica dust (listed under Quartz (respirable dust)) is 0.05 mg/m3 as a TWA (time-weighted average) airborne concentration over 8 hours. An 8-hour time-weighted average exposure standard is the average airborne concentration of a particular substance permitted over an 8-hour working day and 5-day working week.

Rudolf et al., 1988). Workers’ respiratory parameters (tidal volume, Vt, and frequency, f) were associated with their physical activity as follows: Vt = 1450 cm3 f = 15 min-1 (moderate physical activity) Vt = 2150 cm3 f = 20 min-1 (high physical activity) The results show very clearly that oral breathing increases dust deposit in the alveolar
