Effects of Overexposure: Material is classified under OSHA as an inert or nuisance dust and would have the pulmonary effects of inert dust. Glass fabric with resin coating is used in some of the products as a safety reinforcement material.
Emergency and First Aid Procedures: None should be required.
Section VII - Precautions For Safe Handling And Use Precautions to be taken in handling and storage: See ANSI B7.1, store in dry area. Physical damage must be prevented. If damage is suspected, a 100% inspection of all items must be taken.
Other Precautions: 1. Respiratory protection may be required in certain applications of high dust levels. Refer to ANSI 243.1 for additional recommendations. 2. Read and follow all instructions packed with abrasive wheels.
Steps to be taken in case material is released or spilled: Collect material in a safe and convenient manner for reclamation or disposal.
Waste disposal method: Material should be disposed of in a secured, sanitary landfill in accordance with federal, state and local regulations.
Section VIII - Control Measures Respiratory protection (specify type): MSHA or NIOSH approved dust respiratory is required.
Ventilation: Exhaust system with proper filtration should be used. Keep airflow below TLV.
Protective gloves: As desired by user
Eye protection: Required, see OSHA 29CFR1910.133
Other protective clothing or equipment: Hearing protection, see OSHA 29CFR1910.215 (Hearing Protection)
