Chrysotile (White Asbestos) Found in Coal Slag

Earlier in the month, it was discovered that a major producer of abrasive blasting media had been distributing coal slag contaminated with chrysotile, commonly known as white asbestos. Chrysotile is a known human carcinogen that can be extremely harmful when ingested or inhaled. Asbestos has been found to be a direct contributor to “chronic lung disease as well as lung and other cancers.” OSHA notes, “There is no safe level of asbestos exposure for any type of asbestos fiber.”

Silica Dust Suppression with Sponge-Jet

OSHA's Final Rule to protect workers from silica is now in effect. Companies that clean, restore, or prepare concrete and stone now have a greater job site responsibility related to respirable crystalline silica that becomes airborne during this process. In their Final Rule, OSHA has reduced the permissible exposure limit (PEL) for respirable crystalline silica to 50 micrograms per cubic meter of air, averaged over an 8-hour shift. To lower airborne silica created by construction processes, OSHA is requiring companies to add engineering controls to concrete, stone and other masonry cleaning and repair processes.

Sandblasting vs. Abrasive Blasting

Sandblasting has been used as a cleaning method since the 1870s. Benjamin Tilghman, an American inventor from Pennsylvania conceived of the concept of sandblasting and invented the first sand blasting machine. This first machine and concept paved the way for the use of sand blasting in a multitude of industries, including restoration, oil and gas, and ship building.

Beryllium and Abrasive Blasting

On Monday, January 9th, OSHA (Occupational Safety and Health Administration) finalized new beryllium standards for professions commonly exposed to Beryllium. Several are affected including workers in the marine and construction industries. OSHA’s new ruling on Beryllium confirms that at trace levels, beryllium can be harmful. Long-term beryllium exposure can lead to berylliosis, as well as cancer and heart failure. According to author John Emsley, a third of those who contract berylliosis die, leaving the rest permanently disabled.

Abrasive Blasting in Hazardous or Explosive Environments with Sponge-Jet

Sponge-Jet’s abrasive blasting process is unique in that it can be used in areas where traditional abrasive blasting would quickly be ruled out. Power generation, oil and gas, and other industries have embraced the use of blasting with Sponge Media™ abrasives for its ability to achieve high-quality surface preparation and consistent anchor profiles in dust prohibitive environments, even in potentially explosive atmospheres – where combustion of flammable liquids, vapors or combustible dusts exist.

OSHA: Sponge is “Alternative, Less Toxic Blasting Material"

In OSHA’s recent fact sheet, “Protecting Workers from the Hazards of Abrasive Blasting Materials,” abrasive blasting technologies were strongly scrutinized. The fact sheet follows increasing pressure from the general public and industry watchdog groups to include a more holistic approach in protecting those working in and around abrasive blasting operations. The OSHA report discusses health hazards and worker protection methods, stating that, “Employers must protect workers from hazardous dust levels and toxic metals that may be generated from both the blasting material and the underlying substrate and coatings being blasted.”
