Product Name: Sodium Standard Solution Chemical Name: Sodium Chloride Solution CAS Number: 7647-14-5 (for Sodium Chloride) Synonyms: NaCl Solution, Sodium Standard Reference Recommended Use: Analytical calibration standard for laboratory use Supplier Details: Company address, emergency phone number, and available contact person
GHS Classification: Not classified as hazardous according to OSHA Hazard Communication Standard Label Elements: No symbol required; precautionary phrases for laboratory safety practices Hazards: May cause irritation to eyes, skin, or mucous membranes on direct contact; ingestion of large volumes can affect electrolyte balance Precautionary Statement: Avoid unnecessary contact and ingestion; use basic lab hygiene Potential Health Effects: Eye redness, mild skin dryness, upset stomach if swallowed
Main Ingredient: Sodium Chloride Concentration: Typically 1000 mg/L (1 ppm to 10,000 ppm formats common) Solvent Used: Deionized Water Purity: Analytical Reagent Grade – Purity 99.5–100% for sodium chloride component Other Components: None intentionally added Impurities: Trace metals at sub-ppm levels possible
Eye Contact: Rinse under gently flowing water for at least 15 minutes, remove contacts if present, seek medical care with persistent irritation Skin Contact: Wash with soap and water, remove contaminated clothing, get medical attention for persistent irritation Inhalation: Move person to fresh air, supply oxygen or seek medical attention if symptoms like coughing or shortness of breath set in Ingestion: Rinse mouth, drink water, do not induce vomiting, consult physician for large volume ingestion or if symptoms develop Notes for Doctor: Treat symptomatically, monitor for electrolyte disturbances if swallowed in quantity
Suitable Extinguishing Media: Product solution itself is not flammable; use extinguishing media suitable for surrounding fire (CO2, water spray, foam, dry powder) Fire Hazards: Sodium chloride does not support combustion; containers may rupture at high temperatures Protective Equipment: Standard firefighter gear, self-contained breathing apparatus for chemical fumes Specific Hazards: Thermal decomposition may form small amounts of chlorine gas; avoid inhalation of smoke Advice for Firefighters: Prevent spillage and run-off from entering drains and waterways
Personal Precautions: Use gloves and eye protection, avoid splash or prolonged skin contact Spill Clean-Up: Absorb with inert material or non-combustible absorbent (sand, vermiculite); sweep up, place in labeled container for disposal Environmental Precautions: Avoid discharge to drains or watercourses; sodium ions can disrupt sensitive aquatic habitats Additional Measures: Wash contaminated area with plenty of water after clean-up is complete Incident Reporting: Follow facility protocol for reporting chemical spills, document quantity and circumstances
Handling: Open and handle containers carefully to avoid leaks or splashes; always use personal protection; avoid careless transfer between vessels Storage Conditions: Keep containers tightly closed in a cool, dry place away from incompatible materials (acids, strong oxidizers) Storage Temperature: Room temperature preferred; do not freeze; protect from direct sunlight Packaging Material: HDPE bottles, glass containers with non-corrosive lids Special Considerations: Store away from food and beverages to prevent contamination Incompatibilities: Avoid mixing with acidic reagents, silver nitrate solutions, or organic chemicals that may react with sodium ions
Engineering Controls: Use in ventilated laboratory spaces with accessible eyewash stations and sinks Personal Protective Equipment: Lab coat, safety glasses or goggles, chemical-resistant gloves (nitrile or latex) Respiratory Protection: Not required for normal laboratory use; use mask for mist or aerosol generation Hygiene Measures: Wash hands after handling, remove gloves and contaminated PPE promptly Exposure Guidelines: No specific OSHA exposure limits for sodium chloride; general dust and mist levels should not exceed nuisance dust threshold (15 mg/m3 total dust)
Appearance: Clear, colorless aqueous solution Odor: Odorless pH: Neutral to slightly alkaline (6.0–8.0 range depending on concentration) Melting Point: N/A for solution (pure NaCl: 801°C) Boiling Point: Approx. 100°C (water-based) Density (g/cm3): ~1.0 at 20°C, varies with sodium chloride concentration Solubility: Completely soluble in water Vapor Pressure: Similar to water; negligible at RT Other Properties: Non-flammable, not explosive, slight saline taste if tasted accidentally
Chemical Stability: Stable under recommended storage and handling conditions Hazardous Reactions: No dangerous reactions under normal laboratory conditions; vigorous reaction possible with strong acids (release of HCl) Conditions to Avoid: Mixing with concentrated acids, evaporation to dryness can leave solid deposits, extreme heat Incompatible Materials: Strong oxidizers, concentrated mineral acids Hazardous Decomposition: Thermal decomposition can produce chlorine-containing gases at very high temperatures Polymerization: Will not occur
Acute Toxicity: Low toxicity via oral, skin or inhalation exposure; LD50 (oral, rat): ~3000 mg/kg for NaCl Irritation: May cause transient eye and skin irritation Chronic Effects: High or prolonged ingestion can disrupt fluid and electrolyte balance, especially in those with kidney disorders Sensitization: No data suggests skin or respiratory sensitization Other Effects: Inhalation of mist or aerosol may cause mild respiratory tract irritation Carcinogenicity/Mutagenicity: Not classified as carcinogenic or genotoxic by regulatory agencies
Aquatic Toxicity: High concentrations toxic to freshwater species; EC50 (daphnia magna): ~1000 mg/L Persistence and Degradability: Sodium chloride dissociates in water; does not degrade but increases salinity Bioaccumulative Potential: No significant bioaccumulation; ions are essential to biological function in low amounts Mobility in Soil: Highly mobile, migrates rapidly in water and soil Other Harmful Effects: Large discharges can alter ecosystem osmoregulation, disrupt freshwater plant and animal populations Precaution: Avoid chronic releases to waterways, use containment to prevent environmental loading
Waste Treatment Methods: Neutral aqueous waste with low sodium chloride concentrations can often be discharged to municipal sewage with regulatory approval Larger Volumes: Contact local waste disposal authority for advice; landfill for solids, liquid collection for treatment Container Disposal: Triple rinse before recycling or disposal; puncture plastic bottles to prevent reuse Regulatory Restrictions: Follow regional and national rules for chemical waste disposal—documentation and labeling required Special Precautions: Avoid disposal via surface water or storm drains to limit environmental sodium load
UN Number: Not regulated as dangerous goods (solution form; check solid NaCl for bulk shipment) Proper Shipping Name: Not classified as hazardous for air, sea, or land transport Hazard Class: Not applicable Packing Group: Not assigned Special Notes: Standard laboratory mailing; pack to avoid leaks, follow facility procedures for internal shipments
OSHA Status: Not hazardous under OSHA Hazard Communication Standard TSCA Inventory: Listed SARA Title III: Not reportable CERCLA: Not regulated State Regulations: Commonly listed as non-hazardous, consult regional guidance Other Regulations: Sodium chloride present on most major chemical inventory lists; subject to regular workplace labeling and laboratory controls Worker Protection: Maintain records of staff exposure and training as per standard lab safety rules
