Serious Skin Contact: Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek medical attention.
Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
Serious Inhalation: Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt, or waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth resuscitation.
Ingestion: Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. If large quantities of this material are swallowed, call a physician immediately. Loosen tight clothing such as a collar, tie, belt, or waistband.
Section 5: Fire and Explosion Data
Flammability of the Product: Non-flammable.
Fire Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide. Use means suitable for extinguishing surrounding fire.
Explosion Hazards in Presence of Various Substances:
Risks of explosion of the product in presence of mechanical impact: Not available.
Risks of explosion of the product in presence of static discharge: Not available.
Special Remarks on Fire Hazards: Chlorine Trifluoride reacts violently with calcium oxide producing flame.
Extinguishing Media Not recommended: Avoid using water and specially solid water jet.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. At high temperatures under fire conditions, it may produce toxic or irritating fumes. Fire-extinguishing work is done from the windward and the suitable fire-extinguishing method according to the surrounding situation is used. Uninvolved persons should evacuate to a safe place.
Section 6: Accidental Release Measures
Personal precautions, protective equipment, and emergency procedures: Ventilate area of leak or spill. Avoid breathing dust/fumes/gas/mist/vapors/spray. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Restrict unprotected personnel from the area. Prevent any contact with hot surfaces. Do not approach facing the wind. Do not touch the spilled material.
Environmental precautions: Do not let the product enter drains, soil, or water sources.
Methods and materials used for containment cleanup procedures and Storage: Corrosive solid. Stop leak if without risk. Contain spilled material. Cover with an inert, non-combustible absorbent material, (e.g., sand, earth, diatomaceous earth, vermiculite). Vacuum or sweep-up and remove to an approved disposal container. Finish cleaning by spreading water on the contaminated surface and allow to evacuate as per law. Residues can be neutralized with a dilute solution of acetic acid.
Section 7: Handling and Storage
Precautions for safe handling: Never add water to this product. Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. In case of insufficient ventilation, wear suitable respiratory equipment. Wash thoroughly after handling. Do not drink, eat, or smoke while handling. Avoid contact with skin, eyes, and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Prevent any contact with hot surfaces.
Conditions for safe storage, including any incompatibilities: Store in cool, dry, and ventilated area away from heat sources and protected from sunlight in tightly closed original container. Keep air contact to a minimum. Store protected from heat, sparks and ignition sources and incompatible materials. Avoid contact with skin and eyes. Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like organic materials, acids, moisture.
Section 8: Exposure Controls/Personal Protection
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits. If user operations generate dust, fume, or mist, use ventilation to keep exposure to airborne contaminants below the exposure limit.
Exposure Limits:
TWA: 2 (mg/m3) from ACGIH (TLV) [United States]
TWA: 2 (mg/m3) [Canada]
TWA: 5 (mg/m3) from OSHA (PEL).
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator may be worn.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles and/or full-face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures: Maintain good housekeeping in work area. Dust deposits on floors and other surfaces may pick up moisture and cause the surfaces to become slippery and present safety hazards. Handle in accordance with good industrial hygiene and safety practice. Wash hands after handling.
