Notes for Medical Personnel: Treatment should address both local irritation and systemic absorption; supportive care recommended; monitor for signs of manganese poisoning
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Extinguishing Media: Do not use dry combustible materials (like sawdust) due to oxidizer risk
Specific Hazards: Product releases toxic nitrogen oxides under thermal decomposition; intensifies fire with organic materials and reducing agents
Protective Equipment: Use full protective gear including self-contained breathing apparatus
Special Precautions: Move containers away from fire area if safe; keep debris and spilled material away from combustibles; avoid breathing fumes
Firefighting Instructions: Use water to keep containers cool, prevent spread to nearby material; prevent runoff from contaminating waterways and drains
Decomposition Products: Toxic gases, including nitrogen oxides and possibly manganese oxides
Personal Precautions: Evacuate area, keep unprotected individuals away; utilize protective clothing, gloves, and safety goggles; ensure adequate ventilation
Environmental Precautions: Prevent entry into soil, drains, surface water, or groundwater; contain spill to minimize environmental impact
Clean-Up Methods: Sweep solid material carefully into suitable container for disposal; dilute residues with water and collect for authorized disposal; avoid dust formation
Disposal: Collected waste should be properly labeled and disposed through licensed chemical waste handler; use non-combustible absorbents if liquid present
Additional Instructions: Decontaminate affected area with copious water and monitor for surface residue
Handling Procedures: Work only in well-ventilated setting; avoid dust, contact with skin, eyes, and clothing; do not eat, drink, or smoke in work area; handle away from heat, organic materials, and ignition sources
Storage Conditions: Store locked up in original tightly closed container; segregate from acids, ammonium salts, combustibles, and reducing agents; keep in cool, dry, well-ventilated place
Incompatible Materials: Strong acids, alkalis, organic substances, flammable materials, reducing agents
Safe Transfer: Use dedicated tools and equipment to prevent contamination or accidental mixing with incompatible substances
Occupational Exposure Limit: Manganese compounds (as Mn): TLV 0.1 mg/m3 (ACGIH); STEL 3 mg/m3 (OSHA ceiling)
Engineering Controls: Local ventilation, fume hood for laboratory use, minimize dust generation, process enclosure where feasible
Personal Protective Equipment: Chemical splash goggles, gloves (nitrile or PVC recommended), protective laboratory coat or industrial apron, appropriate respiratory protection where exposure risk exists
Hygiene Measures: Wash hands, arms, and face after handling; maintain clean workspace
Environmental Exposure Control: Install suitable filters and containment methods to prevent environmental release; routine monitoring of airborne manganese in industrial workplaces recommended
