| First Aid Measures | Back to Contents | 【Ingestion】
Seek medical assistance. | 【Inhalation】
Move victim to fresh air. Apply artificial respiration if victim is not breathing.

Administer oxygen if breathing is difficult. | 【Skin】
Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. | 【Eyes】
Immediately flush with running water for at least 20 minutes. |

See Inhalation. | 【Hazards】
Vapors form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. | 【UN (DOT)】

| Fire Fighting Measures | Back to Contents | 【Fire Fighting】
Note: Most foams will react with the material and release corrosive/toxic gases. Small Fires: carbon dioxide, dry chemical, dry sand, alcohol-resistant foam. Large Fires: Water spray, fog or alcohol-resistant foam. | 【Fire Potential】
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
ELIMINATE all ignition sources and groumd all equipment used when handling the product. Do not touch spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. A vapor suppressing foam may be used to reduce vapors. FOR CHLOROSILANES, use AFFF alcohol-resistant medium expansion foam to reduce vapors. DO NOT GET WATER on spilled substance or inside containers. Cover with DRY earth, DRY sand, or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain. Use clean non-sparking tools to collect material and place it into loosley covered plastic containers for later disposal. |
