Product Name: Calcium Standard for IC
Primary Use: Laboratory calibration, usually for ion chromatography
Common Forms: Solution, frequently as calcium chloride in water
Appearance: Clear, colorless liquid
Potential Hazards: Direct contact with concentrated solution may cause mild eye or skin irritation, rarely burns or severe reactions; no fumes, but small splashes can create risk during handling; not classified as highly hazardous; not known for chronic toxicity but prolonged exposure should be avoided.
Pictograms: Many suppliers categorize this as low hazard; some labels show exclamation mark for irritant.
Signal Word: Warning, as a prompt to use basic protection
Major Component: Calcium chloride (CaCl₂), generally dissolved in deionized water
Concentration: Typically ranges from 100 mg/L to 1000 mg/L Ca²⁺ depending on intended use
Other Components: Water, possibly trace stabilizers depending on manufacturer; no known hazardous additives in most laboratory formulations
General Tips: Wash off accidentally exposed skin with running water; rinse eyes thoroughly if splashed; do not ingest; seek medical help if discomfort lasts.
Inhalation: Rarely an issue, though move to fresh air if vapors are suspected or if symptoms develop.
Ingestion: Rinse mouth, drink water; call for professional medical advice especially for large accidental intakes.
Skin Contact: Rinse thoroughly; remove contaminated clothing to avoid prolonged exposure.
Eye Contact: Use eye-wash station or clean water for several minutes; medical advice for lingering irritation.
Flammability: Not flammable; solution does not support combustion.
Extinguishing Media: Select for surroundings—water, CO₂, dry chemical, as situation calls for.
Hazardous Combustion Products: Calcium chloride decomposes to hydrogen chloride and calcium oxide under high temperatures, though rare in a lab context.
Special Equipment: Standard fire-fighting PPE suits, avoid inhaling smoke from heated material.
Spill Response: Wear gloves, safety goggles, lab coats; contain spill with absorbent material like paper towels; wipe, then wash area thoroughly.
Environmental Caution: Do not pour large quantities into drains; small, diluted spills pose minimal risk.
Cleanup: Use plenty of water, ventilate area if large spill occurs indoors.
Handling: Use gloves and goggles, especially with concentrated standards; work in well-ventilated lab; wash hands thoroughly after use.
Storage: Store at room temperature, away from incompatible substances like strong acids; keep containers sealed tightly to prevent contamination and evaporation.
Segregation: Keep away from food, drink, and other chemical standards to avoid cross-contamination.
Engineering Controls: Use fume hood for higher concentrations or bulk handling; keep eyewash and safety shower accessible.
Personal Protection: Wear chemical-resistant gloves (nitrile, latex), lab coat, closed footwear, and safety goggles; do not touch face during handling.
Exposure Limits: No specific occupational exposure limits for calcium chloride in laboratory settings; general chemical hygiene applies best here.
State: Liquid solution; solid for concentrated stocks before dilution
Color and Odor: Clear and odorless
Solubility: Dissolves completely in water
pH: Usually neutral to slightly alkaline depending on concentration
Melting/Boiling Point: Aqueous solution nearly matches water’s boiling and freezing points; solid calcium chloride exhibits significant melting point depression
Chemical Stability: Stable at room temperature in aqueous form; avoid mixing with strong acids, bases, or oxidizers
Reactivity: Releases heat when dissolved in water, especially when making concentrated stocks
Decomposition: Only at high temperature, producing calcium oxide and hydrogen chloride; not a typical lab concern
Acute Toxicity: Low; ingestion of small lab quantities unlikely to cause harm, but higher doses cause gastrointestinal irritation
Skin/Eye Contact: Mildly irritating; most issues resolve quickly with rinsing
Chronic Exposure: No evidence of chronic health effects in lab settings
Long-Term Risks: Unlikely from occasional lab exposure, but minimize contact as safety principle
Environmental Impact: Calcium ions are natural water constituents; high localized discharge may increase water hardness, harm some aquatic organisms
Persistence: No bioaccumulation; disperses and dilutes in most environmental settings
Disposal Precaution: Avoid large discharges into surface water or sewage systems without dilution or treatment
Recommended Disposal: Dilute and pour small volumes down drain with running water, according to local laboratory best practice and sewer regulations
Bulk Quantities: Treat as non-hazardous waste, but confirm with local authorities
Container Disposal: Rinse thoroughly before recycling or discarding in trash
Legal Guidance: Follow local and institutional protocols for any chemical waste
Transport Classification: Not regulated as dangerous goods by most transit authorities
Lab Transport: Use sealed containers, secondary containment to prevent leaks during movement
Personal Vehicle: Secure upright, avoid rough handling during transit
Review Required: Consult state and federal safety and environmental regulations
Hazard Classifications: Minimal hazard rating per GHS; not listed as a controlled substance
Label Requirements: Basic safety pictograms and precautionary statements for lab containers
Worker Safety: Aligns with OSHA laboratory standard for hazardous chemicals
