SECTION 2: Hazards identification

OSHA Classification of substance or mixture

2.3 Other hazards

The substance does not meet the criteria for a PBT or vPvB substance Use of this material may generate dust so risk management measures may be needed Emergency overview GBFS is comprised of sand-sized granules. A single short-term exposure to these materials is not likely to cause serious harm. However, exposure to the material when wet can cause serious, potentially irreversible tissue (skin or eye) destruction in the form of chemical (caustic) burns. The same type of tissue destruction can occur if wet or moist areas of the body are exposed for sufficient duration to these materials by chemical (caustic) burns or an allergic reaction.

Potential health effects



Principle Routes of Exposure

Eye contact, skin contact, inhalation, and ingestion  Effects resulting from eye contact: Exposure to airborne dust may cause immediate or delayed irritation or inflammation. Eye contact with larger amounts of dry powder or splashes of these wet materials may cause effects ranging from moderate eye irritation to chemical burns and blindness. Such exposures require immediate first aid. (See section IV) and medical attention to prevent significant damage to the eye.  Effects resulting from skin contact: Discomfort or pain cannot be relied upon to alert a person to a hazardous skin exposure. Consequently, the only efective means of avoiding skin injury or illness involves minimising skin contact, particularly contact with wet GBFS. Exposed persons may not feel discomfort until hours after the exposure has ended and significant injury has occurred. Exposure to dry GBFS may cause drying of the skin with consequent mild irritation or more significant effects attributable to aggravation of other conditions. Dry GBFS contacting wet skin or exposure to moist or wet GBFS may cause more severe skin effects including thickening, cracking or fissuring of the skin. Prolonged exposure can cause severe skin damage in the form of (caustic) chemical burns. Some individuals may exhibit an allergic response (e.g. allergic contact dermatitis) upon exposure to GBFS, possibly due to trace amounts of chromium. The response may appear in a variety of forms ranging from a mild rash to severe skin ulcers. Persons already sensitised may react to the first contact with the product. Other persons may experience this effect after years of contact with GBFS products.  Effects resulting from inhalation: GBFS contains small amounts of free crystalline silica. Prolonged exposure to respirable free silica can aggravate other lung conditions and cause silicosis, a disabling and potentially fatal lung disease and/or other diseases.

(See also”Carcinogenic potential” below). Exposure to GBFS may cause irritation to the mucous membranes of the nose.throat and upper respiratory system. It may also leave unpleasant deposits in the nose.  Effects resulting from ingestion: Although small quantities of dust are not known to be harmful, ill effects are possible if larger quantities are consumed. GBFS should not be eaten. 

2.1 Classification of the substance or mixture

Classification according to Regulation(EC) No. 1272/2008 (which replaces Directive 67/548/EC(DSD) Classification: Not classified. GBFS does not meet the crtiteria for classification in accordance with the regulations EC1272/2008. No special conditions are therefore needed. Risk management measures due to the potential occurrence of hazardous dusts during use as an abrasive may be needed. .
