| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Corrosive hydrogen chloride gas and liquids released upon contact with moisture. Corrosive to skin, eyes and mucous membranes. May be harmful if swallowed. Inhalation of vapor or mists may be fatal. |
| Primary Routes of Exposure: | Ingestion, inhalation, skin, eyes. |
| Eye Contact: | Corrosive to eyes. Causes eye burns and corneal damage |
| Skin Contact: | Contact with moisture of skin produces corrosive hydrogen chloride. |
| Inhalation: | Inhalation causes inflammation of the respiratory tract, edema and chemical pneumonitis. Inhalation may be fatal. |
| Ingestion: | Corrosive to mouth throat and stomach. May cause dizziness, nausea, vomiting, pain and stomach upset. |
| Acute Health Effects: | Contact with skin, eyes and mucous membranes causes burns. Ingestion causes burns to the gastrointestinal tract. Inhalation may be fatal due to inflammation, edema and chemical pneumonitis. |
| Chronic Health Effects: | No information available on long-term chronic effects. |
| NTP: | No |
| IARC: | No |
| OSHA: | No |
| SECTION 4: First Aid Measures | |
|---|---|
| Eye Exposure: | Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention. |
| Skin Exposure: | Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if irritation persists. |
| Inhalation: | Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance. |
| Ingestion: | Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel. |

| Extinguishing Medium: | carbon dioxide or dry powder |
| Special Fire Fighting Procedures: | Fire fighters should be equipped with a NIOSH approved positive pressure self-contained breathing apparatus and full protective clothing. |
| Hazardous Combustion and Decomposion Products: | 'If involved in a fire this material may emit toxic organic fumes and silica dust particulate. |
| Unusual Fire or Explosion Hazards: | No unusual fire or explosion hazards. |
| SECTION 6: Accidental Release Measures | |
|---|---|
| Spill and Leak Procedures: | Small spills can be neutralized with powdered sodium bicarbonate, lime, or calcium carbonate and swept up. Spillage in areas not adequately ventilated will require an evacuation of area. Emergency response teams will require self-contained breathing apparatus. |
| SECTION 7: Handling and Storage | |
|---|---|
| Handling and Storage: | Handle and store the material under a dry atmosphere of nitrogen or argon. Keep in a cool well ventilated place away from sources of ignition. Periodically check bottle caps for cracks. |
