First-aid measures

Inhalation
Remove victim to fresh air while protecting you with appropriate respirator. Remove any contaminated clothing to prevent further inhalation exposure. Use gloves to avoid contaminating yourself. If not breathing, clear victim’s airway and start artificial
respiration. Avoid inhaling expired air. Artificial respiration may be supplemented by use of a bag-mask respirator or manually triggered oxygen supply capable of delivering one litter per second or more. If victim is breathing, supplemental oxygen may be given from a demand-type or continuous-flow inhaler, preferably with a physician’s advice. Monitor breathing and pulse. If victim sops breathing, restart artificial respiration. If heart has stopped, begin cardiopulmonary resuscitation immediately. Keep person warm and at rest. Get medical attention immediately.

Skin contact
Blot excess chemical from the skin very gently and without delay while wearing impervious gloves and air tight safety goggles. If the victim is wearing air tight safety goggles, do not remove them. Take care not to contaminate the victim’s healthy skin and eyes. Wash all affected areas with plenty of soap and water for at least 15 minutes. Do not break open blisters or remove skin. If clothing is stuck to the skin after flushing with water, do not remove it. Do not attempt to neutralize with chemical agents. Wash or discard contaminated clothing and shoes. Obtain medical advice immediately.

Eye contact
Immediately flush eyes with large quantities of running water for a minimum of 15 minutes. If the victim is wearing contact lenses, remove them if it easy to do. Take care not to contaminate the victim’s healthy skin and eyes. Hold the eyelids apart during the flushing to ensure rinsing of the entire surface of the eye and lids. DO NOT let victim rub eye(s). Do not attempt to neutralize with chemical agents. Obtain medical attention as soon as possible. Oils or ointments should not be used at this time. Continue the flushing for an additional 15 minutes if a physician is not immediately available.

Ingestion
Do NOT vomiting. Call a physician immediately. Give victim plenty of water to drink. Never give anything by mouth to an unconscious or convulsing person. Get medical attention immediately.

Fire-fighting measures

Suitable fire extinguishing media:
Dry chemical powder, vermiculite, dry sand.

Specific hazards may be encountered during fire fighting:
This material is pyrophoric. This material reacts spontaneously with air and/or moisture resulting in ignition. In case of fire, reignition of this material occurs after the fire has been extinguished. This material reacts with air, water and compounds containing active hydrogen such as alcohol and acid. Compounds containing oxygen or organic halide may react upon contact with this product. Do not cut, grind, drill or weld on or near the container (even empty) of this product because an explosion may result. Keep away form heat, sparks and flame.

Specific fire-fighting methods:
Protecting against fire by strict adherence to safe operating procedures and proper equipment is the best way to minimize the possibility of fire damage. Immediate action should be taken to confine the fire. All lines and equipment which could contribute to the fire should be shut off. If the fire cannot be controlled with extinguishing agents, keep a safe distance, protect adjacent property and allow to burn until consumed. Human exposure must be prevented and nonessential personnel evacuated from the immediate area.

Special equipment for the protection of fire-fighting:
A standard aluminized firefighting suit is recommended. Breathing vapors from this material fire should be avoided by using proper respiratory equipment. A positive-pressure/pressure demand, air-supplied, full-face respirator should be used.

Accidental release measures

Personal precautions:
Use proper personal gear as indicated in Section 8. Be prepared to fight fire. Eliminate ignition sources.

Environmental precautions:
Protecting against fire by strict adherence to safe operating procedures and proper equipment is the best way to minimize the possibility of fire damage. Immediate action should be taken to confine the fire. All lines and equipment which could contribute to the
fire should be shut off. If the fire cannot be controlled with extinguishing agents, keep a safe distance, protect adjacent property and allow to burn until consumed. Human exposure must be prevented and nonessential personnel evacuated from the immediate area.

Methods for cleaning up:
This material is pyrophoric. The release results in fire. After fire, only aluminum oxide powder is remained. Soak up into a suitable container.

Handling and storage

Handling:
Electrically grounded tanks and containers should be used as should non-sparking, electrically grounded hand tools and appliances. Ground or bond to ground all vessels when transferring to prevent the accumulation of static electricity.

Storage:
Store under an inert atmosphere. Dry nitrogen is a suitable inert gas. Container should be stored in a cool, well-ventilated area away from flammable materials and sources of heat. Exercise due caution to prevent damage to or leakage from this container.

Exposure controls / personal protection

Engineering measures
This material is normally handled under closed process conditions. This product should not be used until all personnel handling it have been thoroughly trained. Contact Tosoh Finechem Corporation additional information on safety and handling of this product is available on metal alkyls. During the development of safe handling procedures, consideration should be given to the need for cleaning of equipment and piping systems to render them nonhazardous before maintenance and repair activities are performed. Safety showers, with quick opening valves which stay open, and eye wash fountains, or other means of washing the eyes with a gentle flow of cool to tepid tap water, should be readily available in all areas where this material is handled or stored. Water should be supplied through insulated and heat-traced lines to prevent freezeups in cold weather.

Respiratory protection:
This material is normally handled under closed process conditions. In an emergency situation where adequate ventilation is not available and condition could generate dust, mist or aerosol, inhalation must be prevent through the use of organic vapor/acid gas respirators with dust, mist and fume filters to reduce potential for exposure. Where exposure potential necessitates a higher level of protection, use a positive-pressure/pressure-demand, air-supplied respirator.

Hand protection:
Impervious gloves such as leather or chemical resistant gloves.

Eye protection:
Chemical goggles and/or a full face shield.

Skin and body protection:
Skin contact must be prevented through the use of fire-retardant clothing. During sampling, disconnecting lines or opening connections, additional protective outerwear including full-face shield, impervious gloves, aluminized suit, a hard hat and chemical safety glasses should also be worn.

Disposal considerations

Methods of waste disposal:
Incineration by controlled feed of air and product is a suitable disposal procedure. Alternatively, deactivation can be achieved by diluting the product with hydrocarbon (heptane, etc.) to less than 5 weight percent aluminum concentration and treating the hydrocarbon solution with water under a nitrogen atmosphere in a vented and agitated container. Allow for the generation of heat and flammable hydrocarbon when treating with water. Conduct water treatment in the absence of air to avoid possible ignition of flammable material. The products from hydrolysis are hydrocarbons and aluminum oxide (hydrated).
