4. First Aid Measures
Always seek medical attention after first aid measures are provided.
Inhalation: Remove affected person to fresh air; if normal breathing has not returned within a few minutes after exposure, get medical attention.
Skin: Remove contaminated clothing; wash affected area with soap and water; launder contaminated clothing before reuse. Seek medical attention.
Eyes: Immediately, flush eyes for 15 minutes in clear running water while holding eyelids open; seek medical attention immediately.
Ingestion: Drink two glasses of water followed by milk, milk of magnesia or other non-alcoholic liquids; Do not induce vomiting; seek medical attention immediately.
Physician may treat symptomatically.
5. Fire Fighting Measures
Flash Point: 133C
General Hazards: Contact with eyes causes immediate severe irritation of the eye and eyelids. Product will support combustion.
Extinguishing Media: Carbon dioxide, water fog, dry chemical, chemical foam. Keep containers cool by spraying with water. Use extinguishing media appropriate for surrounding fire.
Fire & Explosion Hazard: May evolve oxides of carbon (COx) and fumes under fire conditions.
In case of fire, wear a full face positive-pressure self contained breathing apparatus and protective suit. Self - contained respiratory equipment; cool containers to prevent pressure buildup and possible explosion when exposed to extreme heat. Caution - material will support combustion!
Unusual Fire and Explosion Hazards: Closed containers can explode due to buildup of pressure when exposed to extreme heat.
Hazardous Combustion Products: Products of combustion include CO, CO2 and toxic fumes.
6. Accidental Release Measures
Personal precautions, protective equipment and emergency procedures: Avoid breathing dust/fumes/gas/mist/vapors/spray. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc). Restrict unprotected personnel from the area. Prevent any contact with hot surfaces. Do not approach facing the wind.
Environmental precautions: Do not let the product enter sewer, soil or water sources.
Methods and materials used for containment Cleanup procedures and Storage: Contain spilled material. Vacuum or sweep up and remove to an approved disposal container. It will support combustion.
7. Handling and Storage
Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. Wash thoroughly after handling. Do not drink, eat or smoke while handling. Avoid contact with skin, eyes and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc).
Conditions for safe storage, including any incompatibilities: Store in cool, dry and ventilated area away from heat sources and protected from sunlight in tightly closed original container. Keep air contact to a minimum. Do not leave the material container open. Store protected from heat, sparks and ignition sources and incompatible materials. Avoid contact with skin and eyes. Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like bases, acid chlorides, acid anhydrides, oxidizing agents. Keep container closed when not in use; protect containers from abuse; protect from extreme temperatures, open flames. This material will support combustion. Keep this and other chemicals out of reach of children.
8. Exposure Controls/Personal Protection
Engineering Controls: The use of local exhaust ventilation is recommended to control emissions near the source. Provide mechanical ventilation of confined spaces. Use corrosion-resistant, explosion-proof ventilation equipment.
Exposure Limits: ACGIH-TLV 5mg/m3 TWA; OSHA-PEL 5mg/m3
Personal Protection: Respiratory Protection (Specify Type): None required while threshold limits are kept below maximum allowable concentrations; if TWA exceeds standard workplace limits, NIOSH approved respirator must be worn.
Hand Protection: Neoprene, butyl or nitrile rubber gloves with cuffs.
Eye Protection: Chemical safety goggles.
