Inhalation: Remove person to fresh air. Seek medical attention if breathing difficulties or persistent symptoms appear. Loosen tight clothing if any discomfort.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present. Keep eyes open during rinsing.
Skin Contact: Wash thoroughly with mild soap and water. Remove contaminated clothing. Contact healthcare professional if irritation persists.
Ingestion: Rinse mouth with water. Do not induce vomiting. If significant amounts are swallowed or symptoms like nausea, vomiting, or abdominal pain develop, seek immediate medical attention.
Advice for First Responders: Provide symptomatic treatment. Use protective gloves and goggles when administering care to prevent cross-exposure.
Suitable Extinguishing Media: Water spray, foam, dry chemical, or carbon dioxide. Select extinguishing media based on surrounding fire.
Specific Hazards: Decomposition in fires may release irritating fumes of sodium oxides and organic acids. Dust accumulation can cause local combustion if exposed to open flames or high temperatures.
Special Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear.
Advice for Firefighters: Move containers from fire area if possible without risk. Keep area clear of unnecessary personnel.
Personal Precautions: Wear suitable protective equipment such as gloves, goggles, and masks to prevent dust inhalation. Ventilate area.
Environmental Precautions: Avoid release to the environment. Prevent powder from entering waterways or sewage systems.
Methods for Cleanup: Carefully sweep up and shovel spilled material. Place in a labeled container for proper disposal. Wash spill area with water to remove residues.
Reference to Other Sections: Refer to “Personal Protection” and “Disposal” sections for further specific actions and handling.
Safe Handling Procedures: Handle with adequate ventilation. Minimize dust generation and accumulation. Do not eat, drink, or smoke while using this product. Use personal protective equipment as needed.
Storage Conditions: Store in a tightly closed container in a cool, dry, well-ventilated area away from incompatible substances like strong bases or oxidizers. Keep away from moisture to prevent caking.
Incompatibilities: Avoid contact with strong bases, oxidizers, or reducing agents. These can cause decomposition or hazardous reactions.
Special Requirements: Use local exhaust for dusty operations. Label containers clearly with product identifier.
Occupational Exposure Limits: No established exposure limits for sodium hydrogen tartrate. Use general dust control limits (ACGIH TLV for particulates not otherwise classified: 10 mg/m³ (total), 3 mg/m³ (respirable)).
Engineering Controls: Use exhaust ventilation or process enclosure to minimize airborne dust levels. Maintain eyewash stations and safety showers in proximity.
Personal Protective Equipment: Wear chemical-resistant gloves, safety goggles, and dust masks or NIOSH-approved respirators during handling. Use lab coats or coveralls to protect skin.
Hygiene Measures: Always wash hands, forearms, and face after handling and before eating or drinking.
