Are garnet abrasives safe?

BARTON garnet is one of the safest abrasives on the market. Our garnet is a naturally occurring mineral containing zero residual hazardous materials with little to no risk of exposure to quartz and/or heavy metals. BARTON garnet abrasives are low dusting and are environmentally friendly.

Are BARTON garnet abrasives safe to use?

BARTON garnet abrasives are considered non-hazardous. Please see the safety data sheet (SDS) for product properties and safe handling and storing guidelines. Safety data sheets can be downloaded from our library.

Are BARTON garnet abrasives hazardous?

BARTON garnet abrasives are considered non-hazardous. Please see the safety data sheet (SDS) for product properties and safe handling and storing guidelines. Safety data sheets can be downloaded from our library.

How do I find the Safety Data Sheet (SDS) for BARTON abrasives?

Safety Data Sheets (SDS) for BARTON abrasives can be downloaded from our library.

Do BARTON garnet abrasives contain beryllium?

Test data demonstrates that beryllium levels in BARTON garnet are non-detectable; below laboratory detection levels. Learn more about OSHA'S beryllium standard.

Do BARTON abrasives contain respirable free quartz (silica)?

Worker safety is always a priority at BARTON. We regularly test for respirable free quartz levels in our abrasives to ensure concentrations are below 0.1%. Safety data sheets can be downloaded from our library.

What is the difference between total quartz and respirable quartz as listed in the SDS?

Quartz, or silicon dioxide, is a commonly found mineral. The size of the quartz particle determines the inhalation hazard. For example, quartz crystals can grow to be quite large and therefore, do not pose an inhalation hazard. On the SDS for BARTON abrasives, this is described as “Total Quartz”. Worker safety organizations OSHA, NIOSH  and ACGIH agree that it is the respirable crystalline silica fraction that poses the true inhalation health hazard. BARTON has confirmed through an independent Hazard Classification Study that the respirable quartz fraction contained within our garnet abrasives is less than 0.1%.

Do I need to train my employees on the proper handling of garnet abrasives?

Yes. Although BARTON garnet abrasives are considered non-hazardous during normal use and routine clean-up activities, your employees need to understand the proper safe handling measures and work practices when working with any and all materials.

Why is housekeeping so important when using garnet abrasives?

As with any material, housekeeping is paramount to reduce potential employee exposures to any type of dust. During our Hazard Classification Study, we did find a relationship between extremely poor housekeeping conditions and the ability to detect respirable quartz. Although these exposures did not exceed the OSHA PEL, the levels were detectable by NIOSH Method 7500 when housekeeping was poor. As a reminder, as with all dust, wet-methods and/or vacuuming of dusts is the best way to prevent the suspension of dust particles in the air.

What are the OSHA regulations as they relate to BARTON abrasive product offerings?

BARTON abrasive products are subject to OSHA Hazard Communication regulations (29CFR 1910.1200) and are compliant with Global Harmonized System (GHS) standards. Product Safety Data Sheets (SDS) include information such as the properties of the abrasive; the physical, health, and environmental health hazards; protective measures; and safety precautions for handling, storing, and transporting the abrasive. Safety data sheets can be downloaded from our library.

How do I dispose of spent garnet?

Prior to disposing of spent garnet, please review applicable local, state and federal regulations. Although BARTON abrasives are classified as non-hazardous, it is the responsibility of the waste generator to ensure spent materials are disposed in accordance with applicable solid waste regulations. Depending on the waste generation process, additional testing (i.e. Toxicity Characteristic Leaching Procedure (TCLP)) may be required in order accurately assess the proper waste classification.

Why do some other supplier’s garnet abrasive safety data sheets (SDS) say “Danger: May Cause Cancer” and some say nothing at all about quartz?

BARTON has completed the due diligence regarding the proper hazard classification for our garnet abrasives and have had a third-party expert lead a scientific Hazard Classification Study. Not all garnet abrasives are the same nor have all garnet abrasives suppliers undertaken the same rigorous assessment to accurately classify the hazards with their products as we have. We encourage you to develop a relationship with all of your suppliers so that you can be in the best position to ensure the health and safety of your employees.

What industrial hygiene method did you use to assess exposures during the Hazard Classification Study?

We followed NIOSH Method 7500 and used accredited laboratories for determining the crystalline silica concentrations in BARTON garnet abrasives.
