Emergency Contact: National Poison Control Center, local emergency services
Product Description: Silvery-white, soft alkaline earth metal, can appear in solid chunks or granules
GHS Classification: Water-reactive, causes burns, serious eye damage
Primary Hazards: Reacts violently with water, generates hydrogen gas, risk of fire or explosion, causes severe skin and eye burns
Signal Word: Danger
Hazard Statements: Causes severe skin burns and eye damage. Contact with water liberates flammable gas. Hazardous if swallowed or inhaled.
Pictogram: Corrosive, Flammable, Health Hazard symbols
Potential Health Effects: Skin contact causes deep burns; eye contact rapidly damages tissue; ingestion leads to internal burns and possible systemic toxicity; inhalation causes respiratory tract irritation.
Chemical Identity: Calcium
Concentration: >99% for pure calcium product
Impurities: May contain trace levels of magnesium, sodium, barium, or potassium,
Common Additives: None unless specified by manufacturer
Molecular Weight: 40.08 g/mol
General Advice: Seek immediate medical attention in all cases of exposure
Inhalation: Remove to fresh air, monitor breathing, give artificial respiration if not breathing, get medical help
Skin Contact: Brush off dry particles, flush area with copious amounts of water; remove contaminated clothing; do not use ointments or creams before medical evaluation
Eye Contact: Rinse eyes cautiously with water for several minutes, remove contact lenses if easily possible, continue rinsing and seek medical treatment
Ingestion: Do not induce vomiting, rinse mouth, never give anything by mouth to an unconscious person, get immediate medical attention
Delayed Effects: Severe tissue damage, long-term eye injury risk
Special Note: Exposure to combustion byproducts or hydrogen gas requires medical monitoring for possible delayed respiratory symptoms
Suitable Extinguishing Media: Dry sand, Class D extinguishing agents for metal fires (do not use water, CO2 or foam)
Unsuitable Extinguishing Media: Water, halogenated agents, alcohol foam, dry chemical powder not rated for metal fires
Specific Hazards from Fire: Reacts with water releasing hydrogen gas; hydrogen gas forms explosive mixtures with air; highly flammable dust may form from fine particles
Protective Equipment: Wear self-contained breathing apparatus, full protective fire suit
Special Procedures: Cool containers with flooding quantities of dry sand; evacuate area in case of large fire
Decomposition Products: Hydrogen gas, calcium oxide fumes, corrosive and irritant fumes
Personal Precautions: Evacuate unnecessary personnel; wear protective equipment and respiratory protection
Environmental Precautions: Prevent material from entering drains, water systems, or soil
Clean-Up Methods: Sweep up dry calcium using non-sparking tools, collect in a dry, sealable metal container; cautiously sweep wet areas with dry sand; ventilate area
Control of Dust: Avoid generating and breathing dust; use local exhaust or wet method if necessary (never use water directly on spill)
Disposal: Treat as hazardous waste; consult disposal specialist
Safe Handling: Only trained personnel should handle; keep dry; avoid exposure to moisture, acids, and oxidizers
Measures to Prevent Fire and Explosion: Ground containers; avoid creation of dust; keep away from heat and open flames
Storage Conditions: Store in tightly closed containers, under dry inert atmosphere (e.g., argon); keep away from water sources
Incompatible Materials: Water, acids, strong oxidizing agents, halogens
Advice on General Occupational Hygiene: No eating, drinking, smoking in storage or handling area; practice strict personal hygiene
Special Storage Containers: Use non-reactive containers such as stainless steel or glass-lined steel; avoid plastic or containers that may leak air or moisture
Occupational Exposure Limits: ACGIH TLV—Not established for calcium metal; observe limits for nuisance dust if dust is generated
Engineering Controls: Use local ventilation or fume hoods
Personal Protection: Wear chemical resistant gloves (rubber or neoprene), flame-resistant laboratory coat or apron, and safety goggles with face shield
Respiratory Protection: In absence of adequate ventilation or during cleanup, use NIOSH-approved full-face respirator with particulate filter
Environmental Exposure Controls: Minimize release to environment
Hygiene Measures: Always wash hands before breaks and after handling; keep work clothes separate
Appearance: Silvery-white soft metal, can be granular or solid pieces

Boiling Point: 1484°C (2703°F)
Density: 1.54 g/cm³ at 20°C
Solubility in Water: Reacts violently
Vapor Pressure: Negligible at room temperature
Partition Coefficient (n-octanol/water): Not applicable
Decomposition Temperature: Not available
pH: Not applicable
Viscosity: Not applicable
Evaporation Rate: Not applicable
Flash Point: Not flammable as a bulk metal, but flammable as a powder
Autoignition Temperature: Data not available
Upper/Lower Flammability Limits: Data not available; finely divided dust can form explosive mixtures
Chemical Stability: Stable in dry air at room temperature, but surface turns yellow on exposure to air
Conditions to Avoid: Exposure to moisture, water, acids, open flames, and sources of ignition
Incompatible Materials: Water, acids, halogens, oxidizing agents, carbon dioxide, alcohols
Hazardous Decomposition Products: Hydrogen gas, calcium oxide (CaO), heat
Possibility of Hazardous Reactions: Highly reactive with water resulting in ignition and explosion hazard
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Effects: Causes severe burns, eye damage, pain, and blistering at contact points
Chronic Effects: Potential for delayed tissue damage, scarring from severe burns; no reported chronic systemic toxicity for metallic calcium
Symptoms of Exposure: Redness, blistering, pain (skin/eye); coughing, chest tightness (inhalation); burns to mouth, throat (ingestion)
Immediate Medical Attention: Required after significant exposure
Carcinogenicity: Not classified as a carcinogen by IARC, NTP, OSHA
Mutagenicity: No data
Reproductive Toxicity: No data
Aspiration Hazard: Not classified
Aquatic Toxicity: Reacts with water; forms calcium hydroxide resulting in elevated pH and hazard to aquatic life
Mobility in Soil: Limited by reactivity; reacts quickly in moist soils to form stable calcium compounds
Persistence and Degradability: Converts to environmentally persistent calcium salts (calcium hydroxide/carbonate)
Bioaccumulation: Not expected
Adverse Environmental Effects: Large releases may alter pH in aquatic or terrestrial environments, potentially harmful to plants, fish, and aquatic invertebrates
Further Information: Avoid unintentional release to environment; proper waste management is essential to prevent contamination
Waste Treatment Methods: React unneeded material with excess dry sand in a controlled environment, dispose of as hazardous material
Contaminated Packaging: Must be disposed of in accordance with local, regional, and national regulations
