Safety Tips: Routinely Encountered, Silica Requires Special Attention

Crystalline silica, a basic component of soil, sand, granite and other rock materials, is commonly used in occupations which perform such tasks as sand blasting, foundry work, cement mixing, stone cutting, rock drilling, quarry work, and tunneling.  Silica can be inhaled when workers chip, cut, drill or grind objects that contain the substance.  It has been classified as a human lung carcinogen, and breathing crystalline silica dust can cause silicosis, a disabling or even fatal lung condition.

Earlier this month, a company in Massachusetts was cited by OSHA for silica-related hazards identified during restoration work being performed on a bridge.  OSHA issued seven serious citations with proposed fines of $20,100 based on the following conditions:> Employees at jobsite were exposed to excess silica levels while jack hammering concrete
> No controls to lower exposure levels
> Failure to evaluate employees’ exposure levels
> Inadequate respiratory protection program and training
> No fit-testing of respirators

Don’t let this happen at your workplace.  If you’re unsure about the proper treatment of certain chemicals, substances or equipment, consult with an expert.  It’s not worth the risk to do anything less.
