3. Composition/Information on Ingredients

Product Name & Other Names: 8-Hydroxyquinoline or Quinolinol or Oxine.
CAS Number: 148-24-3
EINECS EC Number: 205-711-1

4. First Aid Measures

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

Flammable Limits: No unusual fire or explosion hazards noted.
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.
Organics solids, may be ignitable. Keep containers cool by spraying with water. Use extinguishing media appropriate for surrounding fire.
Fire & Explosion Hazard: May evolve toxic fumes, oxides of carbon (COx), oxides of nitrogen (NOx) 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!
Hazardous Combustion Products: Products of combustion include smoke, toxic fumes, oxides of carbon to include carbon monoxide and nitrogen oxides.
Specific Methods: Cool containers exposed to flames with water until well after the fire is out.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. At high temperatures under fire conditions, it may produce toxic or irritating fumes. Fire-extinguishing work is done from the windward and the suitable fire-extinguishing method according to the surrounding situation is used. Uninvolved persons should evacuate to a safe place.

6. Accidental Release Measures

Personal precautions, protective equipment and emergency procedures: It may support combustion. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. 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. Do not touch the spilled material.
Environmental precautions: Do not let the product enter drains, soil or water sources.
Methods and materials used for containment Cleanup procedures and Storage: Contain spilled material. Cover with an inert, non-combustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite). Vacuum or sweep-up and remove to an approved disposal container.

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. Provide appropriate exhaust ventilation at places where dust is formed. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Prevent any contact with hot surfaces.
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 strong acids & oxidizing agent. 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: Not established.
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.
Other Protective Clothing Or Equipment: Apron, or other equipment should be worn to prevent skin contact, safety eyewash station nearby. Practice safe workplace habits. Minimize body contact with this, as well as all chemicals in general.
