Hazardous Combustion Products: Oxides of carbon and calcium, potentially irritating fumes
Personal Precautions: Avoid dust generation; use personal protective equipment as outlined; ensure adequate ventilation; avoid eye and skin contact
Environmental Precautions: Prevent further leakage or spillage if safe; avoid discharge to drains and waterways
Cleaning Methods: Sweep up and place in sealed, labeled container for reuse or disposal; wash area with water to remove residues
Handling: Minimize dust; use local exhaust ventilation; avoid breathing dust; wear suitable gloves and protective eyewear
Storage: Store in tightly closed containers in a cool, dry, well-ventilated area; protect from moisture, direct sunlight, incompatible chemicals (acids, strong bases); keep away from food and drink
Occupational Exposure Limits: Not established specifically for calcium gluconate; nuisance dust limits apply (ACGIH TLV for particulates not otherwise classified: 10 mg/m³, total dust; 3 mg/m³ respirable dust)
Engineering Controls: Local exhaust, general ventilation
Personal Protective Equipment: Safety glasses or goggles; lightweight gloves; dust mask (NIOSH N95) if airborne dust levels excessive; laboratory coat or apron
Hygienic Practices: Wash hands before breaks and after work; do not eat, drink or smoke during use
