2.2 Label elements

The Hazard Pictograms, Signal Word and Precautionary Statements only apply to activities that may release hazardous substances from the CMU (i.e., cutting / grinding / crushing / drilling / breaking). No Hazard Pictograms, Signal Word or Precautionary Statements are applicable to the CMU Block. Hazard Pictograms that apply to the dust generated from cutting, grinding, crushing, drilling or breaking of the CMU Block

Signal word

Precautionary statements

P260: Do not breathe dust. (For CMU Dust P270: Do not eat, drink or smoke while using this product. Generated from Cutting, P271: Use only outdoors or in a well-ventilated area. Grinding, Crushing, P264: Wash thoroughly after handling. Drilling or Breaking) P280: Wear protective gloves/protective clothing/eye protection/face protection. P302 + P352 IF ON SKIN Wash with plenty of water P304 + P340 IF INHALED Remove person to fresh air and keep comfortable for breathing. P305 + P351 + P338 IF IN EYES Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P314: Get medical advice/attention if you feel unwell. P321: See the SDS for specific treatment. P332 + P313: If skin irritation occurs, get medical advice/attention. P337 + 313: If eye irritation persists, get medical attention. P362 + P364: Take off contaminated clothing and wash before reuse. P501: Dispose of generated dust in accordance with local / regional / national / international regulations. 2.3 Other hazards related to CMU dust generated from cutting, grinding, crushing, drilling or breaking: Listed Carcinogens: Silica dust (respirable, crystalline fraction) in the form of quartz. IARC: Yes NTP: Yes

2.1 Classification of the substance or mixture

Concrete Masonry Units (CMU) are defined by OSHA as an article (under normal conditions, no more than minute or trace amounts of a hazardous chemicals are released and the article does not pose a physical hazard or health risk to employees). No SDS is required for articles; however, this SDS is provided to communicate hazards associated where activities related to the CMU Block (cutting, grinding, crushing, drilling or breaking) may result in the release of a hazardous substance in DUST. GHS Classification(s) for CMU Block according to OSHA Hazard Communication Standard (29 CFR 1910.1200) under normal handling conditions: None GHS Classification(s) for dust generated from cutting, grinding, crushing, drilling or breaking of CMU Block according to OSHA Hazard Communication Standard (29 CFR 1910.1200) under use conditions that may result in the release of hazardous substances: Skin Corrosion/Irritation, Category 2 (H315) Eye Damage/Irritation, Category 2 (H319) Specific Target Organ Toxicity-Repeated Exposure (STOT-RE), Category 1 (H372) Note: The CMU dust classifications are based on (1) individual ingredient classifications (i.e., Silica Sand [SiO2], Limestone, Portland Cement, Fly Ash, etc.), (2) the final chemical composition of the CMU Block (based on cement chemistry) and (3) the form of the material (dust). Further, the Specific Target Organ Toxicity-Repeat Exposure is a conservative classification based on the potential presence of respirable crystalline silica. Boral has not performed analysis for the presence of respirable crystalline silica under these handling conditions.
