Emergency Overview: This product contains crystalline silica which is considered a chronic health hazard by inhalation. The International Agency for Research on Cancer (IARC) has classified occupational exposures to respirable crystalline silica as being carcinogenic to humans (Class 1). This classification is based on what IARC considered sufficient evidence from epidemiological studies of humans for the carcinogenicity of inhaled silica in the forms of quartz and cristobalite. Crystalline silica is also known to cause Silicosis, a non-cancerous lung disease.
Primary Routes of Entry: Via respirable dust, from dry product, to the lungs and respiratory system and via particulate to the eyes.
Primary Target Organs: Lungs, respiratory system and eyes.
Potential Health Effects:
Inhalation: Long term overexposure to respirable crystalline silica dust may cause permanent and irreversible lung damage including silicosis.
Skin Contact: May cause irritation to sensitive skin due to presence of sodium silicate.
Eye Contact: Sodium silicate is corrosive and can cause severe eye irritation and corneal burns.
Ingestion: May cause irritation or mouth burns when ingested. Potentially an Irritant to the GI tract if excessive quantity is ingested.
Medical Conditions Aggravated by Exposure: Dry skin or dermatitis. Product dust will aggravate pre-existing chronic upper respiratory and lung diseases such as, but not limited to, bronchitis, emphysema and asthma.
Carcinogenicity: This product contains crystalline silica which is classified as a class 1, human carcinogen by IARC, as a suspect carcinogen by NTP and as a possible select carcinogen by OSHA.
Inhalation: Remove to fresh air. Drink water to clear throat and blow nose to evacuate dust. If coughing and irritation develop, call a physician.
Eye Contact: Flush with large amounts of water until irritation subsides, as least 15 minutes. See a physician if irritation persists.
Skin Contact: Normal good personal hygiene practices. Wash with mild soap and warm water after each exposure. A skin cream or emollient may soothe skin irritation.
Ingestion: Emergency procedures not normally required. May be a temporary irritant to the GI system.
Clean-up Procedures: Shovel wet spills into container for re-use or disposal. Flush area with water and mop dry. Take care to prevent entry into sewer system.
Personal Precautions: Wear chemical resistant gloves and footwear to guard against chemical burns from sodium silicate.
Environmental Precautions: None normally required.
Storage Requirements: Store in dry area. Keep from freezing. Always segregate materials by major hazard class.
Special Sensitivity or Incompatibility: Avoid contact with strong acids.
Handling Precautions: Assure proper respiratory protection if dust potential exceeds PEL/TLV.
Respiratory Protection: Not normally required when applying wet product. When removing dried product it is prudent to wear an approved face mask such as 3M 8511 N-95 or equivalent, to protect against silica and pneumoconiosis producing dust. Concentrations of dust that exceed the recommendations of the dust mask manufacturer will need a higher level of respiratory protection, such as a half mask respirator with appropriate dust filters.
Eye Protection: Wear safety glasses with side shields or goggles to protect eyes against splashes of wet mortar.
Skin Protection: Under normal conditions the wearing of protective gloves and clean, body-covering clothing should be adequate.
Engineering Controls: Not required during installation of wet product. During tear-out, maintain sufficient mechanical or natural ventilation to assure dust concentrations remain below PEL/TLV. Use local exhaust if necessary. Power equipment should be equipped with properly designed dust collection devices.
Stability: Product is stable under normal conditions.
Hazardous Polymerization: Cannot occur.
Incompatibilities: None in designed use.
Decomposition Products: None.
Conditions to Avoid: None in designed use.
Toxicological Hazards: No toxicological studies of this specific product have been performed.
Ecological Hazards: Most ingredients in this product are naturally occurring minerals. Unless contaminated in service, this product is non-hazardous to the environment.
Teratogenicity, Mutagenicity, other Reproductive Effects: None known
Waste Disposal Method: May be disposed in an approved landfill unless contaminated in service. If contaminated with hazardous materials, place waste in suitable container. Seal and properly label the waste container. Send the container to an approved Transportation, Storage and Disposal (TSD) facility via an approved waste hauler. Be sure manifests have been completed and an adequate "Paper trail" has been established.
OSHA Status: This product is considered hazardous under OSHA criteria.
TSCA/CEPA Status: All components of this product are included in the TSCA and CEPA Chemical Inventories.
