Chemical Product Product Name: Ammonium Chloride Chemical name: Ammonium Chloride Synonyms: Ammonium Chloratum; Ammonium Chloridum; Ammonium Muriate; Sal Ammonia; Salmiac Chemical Formula: NH 4 Cl 2. Composition and Information on Ingredients Composition: Ammonium Chloride Toxicological Data on Ingredients: ORAL (LD50): Acute: 1650 mg/kg [Rat.] 1300 mg/kg [Mouse] 3. Hazards Identification Potential Acute Health Effects: May cause eye and skin irritation, and is slightly hazardous in case of ingestion and inhalation. Potential Chronic Health Effects: CARCINOGENIC EFFECTS: Not Applicable MUTAGENIC EFFECTS: Not Applicable TERATOGENIC EFFECTS: Not Applicable DEVELOPMENTAL TOXICITY: Not Applicable 4. First Aid Measures General measures: Skin contact: Immediately flush skin with plenty of water and afterwards cover irritated skin with an emollient. Seek medical attention. Page 2 of 7

3 Serious skin contact: Wash contaminated area with disinfectant soap and cover with an antibacterial cream. Seek immediate medical attention. Eye contact: Remove any contact lenses and immediately flush eyes with plenty of water for at least 15 minutes. Seek medical attention. Ingestion: Loosen tight clothing such as a collar, tie, belt or waistband. Do not induce vomiting unless directed by medical personnel. Seek medical attention. Serious ingestion: Not Applicable Inhalation: Move victim to fresh air. If not breathing, give artificial respiration and if breathing is difficult, give oxygen. Seek medical attention. Serious inhalation: Not Applicable 5. Fire and Explosion Data Flammability of the Product: Non-flammable Auto-Ignition Temperature: Not Applicable Flash points: Not Applicable Flammable limits: Not Applicable Products of Combustion: Not Applicable Fire Hazards in Presence of Various Substances: Not Applicable Explosion Hazards in Presence of Various Substances: Not Applicable Fire fighting media and Instructions: Not Applicable Special Remarks on Fire Hazards: Reaction between Ammonium Chloride and Bromine pentafluoride at ambient or slightly elevated temperature is violent, and ignition often occurs. Page 3 of 7

4 Special Remarks on Explosion Hazards: Explosive reaction between bromine trifluoride and ammonium halides. 6. Accidental Release Measures NB: Wear appropriate protective equipment/clothing including gloves before removing any spills. Small Spill: Use appropriate tools to put the spilled solid in a convenient waste disposal container and afterwards clean the contaminated area with water. Large Spill: Use a shovel to put the material into a convenient waste disposal container. 7. Handling and Storage Precautions: Avoid contact with skin and eyes and do not breathe dust. Keep away from incompatibles such as oxidising agents, acids, alkalis. Storage: Keep in a tightly closed container which is stored in a cool, well-ventilated area. 8. Exposure Controls/Personal Protection Airborne Exposure Limits: Inhalation TWA: 10 STEL: 20 (mg/m3) [United Kingdom (UK)] Engineering Controls: Use process enclosures, local exhaust ventilation to keep airborne levels low. Personal Protection: Wear splash goggles, lab coat appropriate dust respirator and gloves. 9.
