Firefighting Advice: Approach from upwind, contain runoff to prevent contamination
Personal Precautions: Avoid dust formation, ventilate area, wear gloves, goggles, and disposable mask
Environmental Precautions: Prevent release into surface water and soil, use proper disposal methods for spilled material
Clean-Up Methods: Sweep up material avoiding dust, collect in appropriate waste containers, wash area with water after removal
Waste Handling: Place in leak-proof containers for disposal by approved facility.
Handling: Handle with care to limit dust, keep containers closed, use only in ventilated spaces, wash hands after use
General Hygiene: No food, drink, or smoking in storage and preparation areas
Storage: Store in cool, dry, well-ventilated location, protect from moisture and incompatible substances
Packaging Materials: Use sealed containers, avoid metal storage for extended periods
Incompatible Materials: Strong oxidizers, acids, alkalis
Exposure Limits: OSHA, NIOSH, and ACGIH recommend manganese exposure below 0.2 mg/m³ (as Mn, respirable fraction)
Engineering Controls: Work in local exhaust or fume hood, minimize dust formation
Personal Protection: Wear safety goggles, gloves chemically resistant to manganese salts, dust mask or N95 respirator if airborne powder
Hygiene Measures: Wash hands thoroughly after handling, do not eat or drink while using
Environmental Controls: Air filtration and regular monitoring to limit exposure
Appearance: Light pink to pale brown powder or crystalline solid

Conditions to Avoid: Excess humidity, exposure to hot surfaces, strong acids, strong oxidizers
Incompatible Materials: Strong acids, bases, oxidizing agents
Hazardous Decomposition Products: Manganese oxides, carbon monoxide, carbon dioxide on thermal breakdown
Polymerization: Does not occur
Acute Toxicity: Low toxicity expected by oral, dermal or inhalation routes (LD50 oral rat > 2,000 mg/kg)
Skin Contact: May cause mild irritation on prolonged exposure
Eye Contact: Can cause redness and discomfort if dust or solution gets into eyes
Inhalation: Dust may cause cough, throat, or nasal irritation; not considered a respiratory sensitizer
Chronic Effects: Chronic manganese exposure (from dust or fumes) can impact neurological health (manganism), though risks are much lower with Manganese D-Gluconate compared to metallic manganese or welding fume
Carcinogenicity: Not classified as carcinogen by IARC, NTP, or OSHA
Mutagenicity: Negative in standard bacterial mutation assays
Sensitization: No known sensitizing effects reported
Ecotoxicity: Not highly toxic to aquatic or terrestrial organisms in diluted solutions, excessive or long-term release may impact aquatic environments due to manganese content
Persistence and Degradability: Readily biodegradable, D-Gluconate breaks down naturally, manganese integrates into soil minerals
Bioaccumulation Potential: Low potential due to solubility and natural cycling of manganese
Mobility in Soil: Highly soluble, can enter groundwater; avoid uncontrolled release
Other Adverse Effects: Use in accordance with local environmental guidelines reduces impact
Disposal Methods: Dispose through approved chemical waste system in accordance with local, regional, and national regulations
Contaminated Packaging: Clean completely for recycling or dispose as hazardous waste
Special Precautions: Do not pour into drains, bodies of water, or sewers
Regulatory Waste Code: Consult local waste authorities for classification
