| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Irritating to skin, eyes and respiratory tract. |
| Primary Routes of Exposure: | Inhalation, ingestion, contact with skin and eyes. |
| Eye Contact: | Causes severe irritation of the eyes. Delayed blindness may occur through atrophy of the optic nerve. |
| Skin Contact: | Dehydrating agent. Liquid causes mild irritation of the skin. |
| Inhalation: | Methanol vapor is irritating to the respiratory tract and cause headache, dizziness, coma, and blindness. |
| Ingestion: | Ingestion may cause nausea, vomiting, headache, coma and death. |
| Acute Health Effects: | Methanol may irritate the skin, eyes and respiratory tract, cause blurred vision, blindness, intoxication, dizziness, headache, nausea, coma and death. |
| Chronic Health Effects: | Rapid hydrolysis on human contact produces methanol, which is metabolized slowly to formaldehyde. Gradual atrophy of the optic nerve may occur producing blindness. |
| NTP: | No |
| IARC: | No |
| OSHA: | No |
| SECTION 4: First Aid Measures | |
|---|---|
| Eye Exposure: | Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention. |
| Skin Exposure: | Wash the affected area with soap and water. Remove contaminated clothes if necessary. Seek medical assistance if irritation persists. |
| Inhalation: | Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance. |
| Ingestion: | Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). |
| SECTION 5: Fire Fighting Measures | |
|---|---|
| Flash Point: | not applicable |
| Autoignition Temperature: | no data |
| Explosion Limits: | no data |
| Extinguishing Medium: | carbon dioxide, dry powder or foam |
| Special Fire Fighting Procedures: | If involved in a fire, fire fighters should be equipped with a NIOSH approved positive pressure self-contained breathing apparatus and full protective clothing. |
| Hazardous Combustion and Decomposion Products: | If involved in a fire this material may emit toxic organic fumes and tantalum oxide dust. |
| Unusual Fire or Explosion Hazards: | Highly flammable. Formation of explosive air/dust mixtures is possible. |
| SECTION 6: Accidental Release Measures | |
|---|---|
| Spill and Leak Procedures: | Eliminate all ignition sources. Avoid contact with water. Small spills may be adsorbed into diatomaceous earth, sand, or other suitable adsorbent, and swept up. |
| SECTION 7: Handling and Storage | |
|---|---|
| Handling and Storage: | Store in a tightly sealed container in a dry place. If container is left open, product may adsorb moisture from the atmosphere and release methanol vapor. |
| SECTION 8: Exposure Controls and Personal Protection | |
|---|---|
| Eye Protection: | Always wear approved safety glasses when handling a chemical substance in the laboratory. |
| Skin Protection: | Wear protective clothing and gloves. |
| Ventilation: | Material may form a vapor upon exposure to air. if possible, handle the material in an efficient fume hood. |
| Respirator: | If ventilation is not available a respirator should be worn. The use of respirators requires a Respirator Protection Program to be in compliance with 29 CFR 1910.134. |
| Additional Protection: | No additional protection required. |
