SECTION 4: First aid measures

Inhalation If adverse effects occur, remove to uncontaminated area. Give artificial respiration if not breathing. If breathing is difficult, oxygen should be administered by qualified personnel. Get immediate medical attention. Skin contact Wash skin with soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get immediate medical attention. Thoroughly clean and dry contaminated clothing before reuse. Destroy contaminated shoes. Eye contact Immediately flush eyes with plenty of water for at least 60 minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Then get immediate medical attention. Ingestion If swallowed, do NOT induce vomiting. Rinse mouth. Get immediate medical attention. Most Important Symptoms/Effects Acute Fatal if inhaled, toxic if swallowed, respiratory tract burns, skin burns, eye burns, mucous membrane burns Delayed No information on significant adverse effects. Indication of any immediate medical attention and special treatment needed None known. Note to Physicians For inhalation, consider oxygen. Avoid gastric lavage or emesis.

SECTION 5: Firefighting measures

Flammable Properties Negligible fire hazard. Oxidizer. May ignite or explode on contact with combustible materials. Avoid generating dust; fine dust dispersed in air in sufficient concentrations, and in the presence of an ignition source is a potential dust explosion hazard. Suitable extinguishing media Water, Large fires: Flood with water. Apply water from a protected location or from a safe distance. Unsuitable Extinguishing Media Do not use dry chemicals or foams. Special Hazards Arising from the Chemical Negligible fire hazard. Oxidizer. May ignite or explode on contact with combustible materials. Avoid generating dust; fine dust dispersed in air in sufficient concentrations, and in the presence of an ignition source is a potential dust explosion hazard.

halogenated compounds Fire Fighting Measures Move container from fire area if it can be done without risk. Cool containers with water spray until well after the fire is out. Stay away from the ends of tanks. For fires in cargo or storage area: Cool containers with water from unmanned hose holder or monitor nozzles until well after fire is out. Flood with water. Apply water from a protected location or from a safe distance. Avoid inhalation of material or combustion by- products. Stay upwind and keep out of low areas. Evacuate if fire gets out of control or containers are directly exposed to fire. Evacuation radius: 800 meters (1/2 mile). Special Protective Equipment and Precautions for Firefighters Wear full protective fire fighting gear including self contained breathing apparatus (SCBA) for protection against possible exposure.

SECTION 6: Accidental release measures

Personal precautions, protective equipment and emergency procedures Wear personal protective clothing and equipment. Environmental precautions Avoid release to the environment. Methods and Materials for Containment and Cleaning Up In case of fire, use media appropriate for extinction. Stop leak if possible without personal risk. Keep unnecessary people away, isolate hazard area and deny entry. If sweeping of a contaminated area is necessary, use a dust suppressant agent. Avoid contact with combustible materials. Do not touch spilled material. Do not get water inside container. Collect spill using a vacuum cleaner with a HEPA filter or wet and scoop up dry spills. Avoid sweeping spilled dry material. Eliminate ignition sources including sources of electrical, static or frictional sparks. Small spills: Collect spilled material in appropriate container for disposal. Move containers away from spill to a safe area. Large spills: Dike for later disposal.

SECTION 7: Handling and storage

Precautions for safe handling Keep away from heat. Keep/store away from clothing and other combustible materials. Take any precaution to avoid mixing with combustibles. Do not breathe dust. Wear protective gloves/clothing and eye/face protection. Wear respiratory protection. Use only outdoors or in a well-ventilated area. Do not eat, drink, or smoke when using this product. Wash thoroughly after handling. Use methods to minimize dust. Avoid significant deposits of material, especially on horizontal surfaces, which may become airborne and form combustible dust clouds and may contribute to secondary explosions. Conditions for safe storage, including any incompatibilities Store in a well-ventilated place. Keep container tightly closed. Store locked up. Store and handle in accordance with all current regulations and standards. Store under an inert atmosphere. Avoid contact with water or moisture. Keep separated from incompatible substances. Incompatible Materials combustible materials, metals, oxidizing materials, reducing agents
