First Aid Measures

Ingestion
Get medical aid. Wash mouth out with water.
Inhalation
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Skin
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
Eyes
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.

Handling and Storage

Storage
Keep away from sources of ignition. Store in a cool, dry place. Store in a tightly closed container.
Handling
Use only in a well ventilated area. Avoid breathing dust, vapor, mist, or gas. Avoid contact with skin and eyes.

Hazards Identification

Ingestion
Harmful if swallowed. Symptoms of quinine overdose can include loss of visual acuity, narrowing of the field of vision, partial to complete blindness, loss of light sensitivity, dilation of the pupils with no response to light, and partial to complete loss of hearing. The natural course is for some spontaneous recovery to occur, but the recovery may not be complete. (Grant and Schuman, Toxicology of the Eye, 4th
Inhalation
Harmful if inhaled. Causes respiratory tract irritation.
Skin
Causes skin irritation. Harmful if absorbed through the skin.
Eyes
Causes eye irritation.

Exposure Controls/Personal Protection

Personal Protection
Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
Respirators
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.

Fire Fighting Measures

Flash Point
75
Autoignition
409
Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Combustible Liquid. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam.

Accidental Release Measures

Small spills/leaks
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container.

Stability and Reactivity

Stability
No data.
Incompatibilities
Strong oxidizing agents.
Decomposition
Carbon monoxide, oxides of phosphorus, carbon dioxide.
