CAS Number: 16079-88-2 

Percent: 98% 

Eye Contact: Check for and remove any contact lenses. Flush with copious amounts of water for at least 15 minutes. Assure adequate flushing by separating the eyelids with fingers. Get medial aid immediately. 

Skin Contact: Immediately wash skin with soap and copious amounts of water while removing contaminated clothing and shoes. Cover the irritated skin with an emollient. Cold water may be used. Wash clothing before reuse. Thoroughly clean shows before reuse. Get medical attention immediately. 

Inhalation: Remove from exposure and move to fresh air immediately. Loosen tight clothing such as a collar, tie, belt, or waistband. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Seek medical attention if irritation develops or persists. WARNING: It may be hazardous to the person providing aid to give mouth-to-mouth resuscitation when the inhaled material is toxic, infections or corrosive. Seek immediate medical attention. 

Ingestion: Do not induce vomiting. Never give anything by mouth to an unconscious person. Wash out mouth with water. Get medical aid. Loosen tight clothing such as a collar, tie, belt or waistband. Examine the lips and mouth to ascertain whether the tissues are damaged, a possible indication that the toxic material was ingested; the absence of such signs, however, is not conclusive. 

Notes To Physician: Treat symptomatically. 

Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Use water spray to cool unopened containers. 

Special Hazards Arising from the Substance or Mixture: Contact with other material may cause fire. May accelerate combustion. Forms explosive mixtures with air on intense heating. May emit toxic fumes under fire conditions. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion. Keep product and empty container away from heat and sources of ignition. 

Advice for Firefighters: As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full protective gear. 

Personal Precautions, Protective Equipment and Emergency Procedures: If packages rupture. Ensure adequate ventilation. Use personal protective equipment. Keep people away from and upwind of spill/leak. Evacuate personnel to safe areas. Eliminate all ignition sources (no smoking, flares, sparks or flames in the immediate area). Keep combustibles (wood, paper, oil, etc.) away from spilled material. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Keep substance wet using water spray. Avoid dust formation. Avoid breather dust, vapor, mist, or gas. Shut off source of the leak only if it is easy to do so. Do not get water inside containers. 

Environmental Precautions: Take precautions to ensure product does not contaminate the ground or enter the drainage system, surface water, sanitary sewer or ground water system. 

Methods and Materials For Containment and Cleaning Up: Contain spillage, and then collect with non-combustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite) and place in container for disposal according to local / nation regulations (see section 13). Keep in suitable, closed containers for disposal. 

Precautions for Safe Handling: In accordance with good industrial practice, handle with care and avoid unnecessary personal contact. Use with adequate ventilation. Avoid breathing dust, vapor, mist, or gas. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation. Avoid prolonged or repeated exposure. Avoid physical damage to the container. Empty containers retain product residue, (dust and/or solids), and can be dangerous. Keep away from open flames, hot surfaces and sources of ignition. Keep away from heat and direct sunlight. Use only non-sparking tools. Use explosion-proof equipment. Ground and bond containers when transferring material. Take precautionary measures against static discharges. No smoking, eating and drinking water at workplace. Before break and at the end of work hands should be thoroughly washed. Do not allow water to get into the container. Keep away from incompatibles such as reducing agents, combustible materials, organic materials, acids. 

Conditions for Safe Storage, Including Any Incompatibilities: Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances and foodstuff containers. Keep away from heat, sparks and open flames. Keep away from sources of ignition. Keep away from direct sunlight. Keep away from moisture and water. Keep away from combustible materials and wooden floors. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Keep out of reach of children. 

Exposure Limits: No data available 

Engineering Controls: Ensure adequate ventilation, especially in confined areas. Use explosion-proof electrical/ventilating/lighting/equipment. Ensure that eyewash stations and safety showers are close to the workstation location. 

Personal Protective Equipment: 

• Eyes Protection: Wear chemical splash goggles 

• Skin Protection: Wear appropriate protective gloves 

• Body Protection: Choose body protection according to the amount and concentration of the dangers substance at the workplace.

Potential Health Effects: 

Eye: Corrosive to eyes. Eye contact can result in corneal damage or blindness. 

Skin: Hazardous in case of skin contact (sensitizer). The amount of tissue damage depends upon length of contact. Skin contact can produce inflammation and blistering. Prolonged exposure may result in skin burns and ulcerations. 

Ingestion: Harmful if swallowed. Causes chemical burns to the mouth, throat, esophagus and gastrointestinal tract. Risk of perforation in the esophagus and stomach. Swallowing concentrated chemical may cause sever internal injury. 

Inhalation: Inhalation of dust will produce irritation to gastrointestinal or respiratory tract, characterized by burning, sneezing, coughing and wheezing. Overexposure by inhalation may cause respiratory irritation. May be fatal if inhaled. 

Symptoms of Exposure: Repeated exposure of the eyes to a low level of dust can produce eye irritation. Repeated skin exposure can produce local skin destruction or dermatitis. Repeated inhalation of dust can produce varying degrees of respiratory irritation or lung damage. Repeated exposure to a highly toxic material may produce general deterioration of health by an accumulation in one or many human organs. To the best of our knowledge, the chemical, physical, and toxicological properties have not been thoroughly investigated. 

Waste from Unused Products: Chemical waste generators must determine whether a discarded chemical is classified as a hazardous waste. Additionally, waste generators must consult state and local hazardous waste regulations to ensure complete and accurate classifications.
