FIRST AID

  Inhalation:                                                  Remove to fresh air. If breathing is difficult, have a
trained individual
                                              administer oxygen. If not breathing, give artificial respiration and have a
                                              trained individual administer oxygen.            Get medical attention
                                              immediately.

 Eyes:                                                         Use an eyewash to remove a chemical from your eye
regardless of
                                              the level of hazard. Flush the affected eye for at least twenty minutes.
                                              Tilt the head to prevent chemical from transferring to the
                                              uncontaminated eye. Seek medical advice after flushing.

  Skin Contact:                                                Wash with soap and water. Get medical attention if
irritation
                                              develops or persists.

 Ingestion:                                                    Do not induce vomiting and seek medical attention
immediately.
                                              Drink two glasses of water or milk to dilute. Provide medical care

FIRE FIGHTING MEASURES

 Flammability Summary:                      Combustible at elevated temperatures.

 Flash Point:                                                                                           400 deg. F
                                                         240 deg. C

 Auto-ignition Temperature:                              460 deg. C

 Fire Hazards:                                                        Material may be ignited only if preheated to
temperatures above the
                                              high flash point, for example in a fire. Empty containers that retain
                                              product residue (liquid, solid/sludge, or vapor) can be dangerous. Do
                                              not pressurize, cut weld, braze, solder, drill, grind, or expose container
                                              to heat, flame, sparks, static electricity, or other sources of ignition. Any
                                              of these actions can potentially cause an explosion that may lead to
                                              injury or death.
                                              Dust explosions can occur under conditions of high dust concentrations
                                              in the presence of an ignition source. Burning will produce irritating
                                              smoke.
                                              Water Reactive. Material will react with water and may release a
                                              flammable gas.

                                                      APPLIED SEMICONDUCTOR, INC.


 Extinguishing Media:                                        Use alcohol resistant foam, carbon dioxide, or dry
chemical when
                                            fighting fires. Water or foam may cause frothing if liquid is burning but it
                                            still may be a useful extinguishing agent if carefully applied to the
                                            surface of the fire. Do not direct a stream of water into the hot burning
                                            liquid.


Fire Fighting Instructions:Do not enter fire area without proper protection including self-contained
                                           breathing apparatus and full protective equipment. Empty containers
                                           that retain product residue (liquid, solid/sludge, or vapor) can be
                                           dangerous. Do not pressurize, cut, weld, braze, solder, drill, grind, or
                                           expose container to heat, flame, sparks, static electricity, or other
                                           sources of ignition. Any of these actions can potentially cause an
                                           explosion that may lead to injury or death.
                                           Dust explosions can occur under conditions of high dust concentrations
                                           in the presence of an ignition source. Burning will produce irritating
                                           smoke.
                                           Water Reactive. Material will react with water and may release a
                                           flammable gas.

ACCIDENTAL RELEASE MEASURES

 Health Consideration for Spill No adverse health affects expected from the clean-up of spilled
 Response:                               material. Follow personal protective equipment recommendations
                                         found in Section VIII of this MSDS.


Spill Mitigation Procedures:
 General Methods:                                            No special spill clean-up considerations. Collect and
discard in
                                            regular trash.


VII. HANDLING AND STORAGE

 Handling:                                  No special handling instructions due to toxicity. As with all chemicals,
                                            good industrial hygiene practices should be followed when handling this
                                            material. Wash thoroughly after handling. Avoid contact with material.
                                            Use spark-proof tools and explosion-proof equipment. Ground and
                                            bond containers when transferring material. Avoid creating dusts as an
                                            explosive dust air mixture can be created at high concentrations. If
                                            dusts are created ensure no sources of ignition are present. Take
                                            precautionary measures to prevent electrostatic discharges. Minimize
                                            dust generation and accumulation. Remove contaminated clothing and
                                            wash before reuse. “Empty” containers retain product residue (liquid
                                            and/or vapor) and can be dangerous.

 Storage:                                   Store in a cool dry place. Isolate from incompatible
                                            materials. Keep away from heat, sparks, and flame.

 Engineering Controls:                        Local exhaust ventilation or other engineering controls are normally
                                              required when handling or using this product to avoid overexposure.
                                              Engineering controls must be designed to meet the OSHA chemical
                                              specific standard in 29 CFR 1910. Explosion proof exhaust ventilation
                                              should be used.

Protective Equipment:                         Respiratory protection may be required to avoid overexposure when
 Respiratory Tract:                           handling this product. General or local exhaust ventilation is the
                                              preferred means of protection. Use a respirator if general room
                                              ventilation is not available or sufficient to eliminate symptoms. Follow a
                                              respiratory protection program that meets 29 CFR 1910.134 and ANSI
                                              Z88.2 requirements whenever work place conditions warrant the use of
                                              a respirator. Wear a NIOSH approved respirator if any exposure is
                                              possible.

  Eyes:                                       Wear safety glasses when handling this product. Wear goggles and a
                                              Face shield . Wear goggles if dust can reach the exposure limit.

  Skin:                                       Avoid skin contact by wearing chemically resistant gloves, an apron
                                              and other protective equipment depending upon conditions of use.
                                              Inspect gloves for chemical break-through and replace at regular
                                              intervals. Clean protective equipment regularly. Wash hands and other
                                              exposed areas with mild soap and water before eating, drinking, and
                                              when leaving work.
