First Aid Measures

Ingestion

If swallowed, wash out mouth with water provided person is conscious. Call a physician.

Ingestion

If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.

Ingestion

Seek medical assistance.

Inhalation

TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns, or death. Effects may be delayed.

Inhalation

May be harmful if inhaled. Material is irritating to mucous membranes and upper respiratory tract.

Inhalation

Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult.

Inhalation

Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.

Inhalation

If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen.

Skin

Causes irritation. May be harmful if absorbed through the skin.

Skin

Get medical aid immediately. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.

Skin

In case of contact, immediately wash skin with soap and copious amounts of water. Remove contaminated clothing and shoes. Call a physician.

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.

Skin

See Inhalation.

Eyes

Immediately flush with running water for at least 20 minutes.

Eyes

In case of contact with eyes, flush with copious amounts of water for at least 15 minutes. Assure adequate flushing by separating the eyelids with fingers. Call a physician.

Eyes

See Inhalation.

Eyes

Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.

Eyes

Causes severe eye irritation.

Handling and Storage

Storage

Keep container tightly closed.

Storage

Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.

Storage

Store in a cool, dry place. Store in a tightly closed container. Refrigerator (approx 4 C). Store protected from light.

Handling

Wash thoroughly after handling. Use only in a well ventilated area. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation. Store protected from light.

Handling

All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.

Hazards Identification

Ingestion

Harmful if ingested.

Ingestion

May cause digestive tract disturbances. The toxicological properties of this substance have not been fully investigated.

Ingestion

See Inhalation.

Inhalation

May cause respiratory tract irritation. The toxicological properties of this substance have not been fully investigated.

Skin

May cause skin irritation. The toxicological properties of this material have not been fully investigated.

Eyes

May cause eye irritation. The toxicological properties of this material have not been fully investigated.

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.

Hazards

Emits toxic fumes under fire conditions.

Exposure Controls/Personal Protection

Personal Protection

Compatible chemical-resistant gloves. Chemical safety goggles. Protective clothing.

Personal Protection

Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.

Personal Protection

Wear appropriate protective gloves, clothing and goggles.

Respirators

Wear positive pressure self-contained breathing apparatus (SCBA).

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.

Respirators

Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU). Where risk assessment shows air-purifying respirators are appropriate use a full-face particle respirator type N99 (US) or type P2 (EN 143) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator.

Fire Fighting

Extinguish with water spray, carbon dioxide, dry chemical powder or appropriate foam. Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.

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 Fighting

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Extinguishing media: Use agent most appropriate to extinguish fire. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.

Fire Potential

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.

Accidental Release Measures

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.

Small spills/leaks

Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Avoid generating dusty conditions. Provide ventilation.

Small spills/leaks

Sweep up, place in a bag and hold for waste disposal. Avoid raising dust. Ventilate area and wash spill site after material pickup is complete.
