*  WARNING:  This product may contain  a small amount of crystalline silica, which may cause delayed respiratory disease if inhaled over a prolonged period of time.  Avoid breathing the dust.  Use NIOSH/MSHA approved respirator where TLV for crystalline silica (quartz) may be exceeded.  IARC Monographs on the evaluation of the Carcinogenic Risk of Chemicals to Humans (volume 68, 1997) concludes that crystalline silica is carcinogenic to humans in the form of quartz.  IARC classification 1.

 

The small quantities of crystalline silica (Quartz) found in this product are, under normal conditions, naturally  coated with an unremoveable layer of amorphous silica and/or bentonite clay.  IARC (vol. 68, 1997, PP 191-192) has stated that crystalline silica (quartz) can differ in toxicity depending on the minerals with which it is combined, citing studies in IARC (vol. 42, 1987, P. 86) which stated that the toxic effect of crystalline silica (quartz) is reduced by the "protective effect….due mainly to clay minerals…"

 

National Institute for Occupational Safety and Health (NIOSH) has recommended that the permissible exposure limit be changed to 50 micrograms respirable free silica per cubic meter of air (0.05 mg/m³) as determined by a full shift sample up to a 10 hour working day, 40 hours per week.  See: 1974 NIOSH criteria for a recommended Standard for Occupational Exposure to Crystalline Silica should be consulted for more detailed information.

 

 

 

 

 

3.    HAZARDS IDENTIFICATION

 

Emergency Overview:    Route(s) of Entry:    Inhalation? Yes    Skin?  No  Ingestion?  No

 

 

Potential Health Effects  (Acute and Chronic): 

 

Inhalation:  Breathing silica dust may not cause noticeable injury or illness even though permanent lung damage may be occurring.  Inhalation of dust may have the following serious chronic health effects:

 

Silicosis:  Excessive inhalation of respirable crystalline silica dust may cause a progressive, disabling and sometimes-fatal lung disease called silicosis.  Symptoms include cough, shortness of breath, wheezing, non-specific chest illness and reduced pulmonary function.  Smoking exacerbates this disease.  Individuals with silicosis are predisposed to develop tuberculosis.

 

Cancer Status:  The International Agency for Research on Cancer has determined that crystalline silica inhaled in the form of quartz or critobalite from occupational sources is carcinogenic to humans. (group 1 – carcinogenic to humans).  Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibers (published in June 1997) in conjunction with the use of these materials.  The National Toxicology Program classifies respirable crystalline silica as "reasonably anticipated to be a carcinogen".  For further information See: "Adverse Effects of Crystalline Silica Exposure" published by the American Thoracic Society Medical Section of the American Lung Association, American Journal of Respiratory and Critical Care Medicine, Volume 155, Page 761-765, 1997.

 

Other Data with Possible Relevance to Human Health:

                                                                                                                                                                                  

       The small quantities of crystalline silica (quartz) found in this product are, under normal

       conditions, naturally coated with an unremovable layer of amorphous silica and/or bentonite clay.

       IARC (vol. 68, 1997, pg 191-192) has stated that crystalline silica (quartz) can differ in toxicity

       depending on the minerals with which it is combined, citing studies in IARC (Vol. 42, 1987, pg.

       86) which stated that the toxic effect of crystalline silica (quartz) is reduced by the "protective

       effect…. Due mainly to clay minerals…".

 

        Carcinogenicity:       NTP?  No      IARC Monographs?  No          OSHA Regulated?  No

 

        Medical Conditions Generally Aggravated by Exposure:

 

        Individuals with respiratory disease, including but not limited to, asthma and bronchitis, or

        subject to eye irritation should not be exposed to respirable crystalline silica (quartz) dust.

                                                                                                                                                                                   

 

4.    FIRST AID MEASURES

 

Inhalation:    Gross inhalation of dust, remove to fresh air, give oxygen or artificial respiration

if necessary, get medical attention.

 

Eye Contact:    Flush eyes for at least 15 minutes and get medical attention if needed.
