Ingestion: Do not induce vomiting, rinse mouth with water, give nothing by mouth, call poison center or physician
Delayed Effects: Watch for mercury poisoning symptoms such as numbness, tremors, or visual disturbances; inform medical professionals immediately
Recommended Immediate Medical Attention: All routes of exposure may require specialist consultation for mercury toxicity
Suitable Extinguishing Media: Dry chemical powder, carbon dioxide, foam; avoid using water spray directly on material to reduce run-off
Specific Hazards: Decomposes generating corrosive, toxic fumes including chlorine, mercury vapor, and phosgene
Special Protective Equipment: Self-contained breathing apparatus, full protective suit, keep all nonessential personnel away
Fire-Fighting Advice: Dike fire-control water for later disposal, keep away from water sources, ventilate area post-fire
Explosion Data: Not expected to present explosion hazard under normal conditions
Personal Precautions: Evacuate unnecessary personnel, ventilate confined spaces, wear appropriate PPE including mercury vapor mask, impermeable gloves, and goggles
Methods for Containment: Avoid release to environment, use inert absorbent materials (sand, earth, vermiculite), do not allow entry into drains, surface water, or soil
Cleanup Methods: Collect spilled material using chemical vacuum or scoop into chemical waste container, double bag for transport, decontaminate area with dilute bleach solution
Environmental Precautions: Notify regulatory authorities if release contaminates water or soil; avoid actions increasing airborne dust
Precautions for Safe Handling: Work in chemical fume hood, avoid direct contact with skin or eyes, do not eat, drink, or smoke in work area, use tools to minimize handling, wash hands after use
Conditions for Safe Storage: Keep locked and away from incompatible substances in cool, dry, well-ventilated place with secondary containment, store in tightly closed original container
Storage Incompatibilities: Strong oxidizing agents, acids, bases, reducing agents; avoid proximity to food, feed, and potable water
Special Storage Requirements: Clearly label container, restrict access to authorized personnel only, keep storage records as per local regulation
Occupational Exposure Limits: OSHA PEL for mercury compounds: 0.1 mg/m³ (as Hg), ACGIH TLV: 0.025 mg/m³ (as Hg)
Engineering Controls: Use in chemical fume hood, provide adequate exhaust and general area ventilation, use closed systems for transfer
Personal Protective Equipment: Chemical-resistant gloves (nitrile, butyl rubber), body-covering protective clothing, goggles or full-face shield, respiratory protection (mercury vapor cartridge respirator or supplied-air apparatus for large-scale work)
Hygiene Measures: Wash hands, forearms, and exposed skin frequently, do not touch face or take contaminated materials outside controlled area, remove contaminated clothing and wash before reuse

Symptoms: Nausea, vomiting, abdominal pain, respiratory distress, skin or eye burns, neurological disturbances, tingling or numbness
Carcinogenicity: Not classified as carcinogenic by IARC, but classified as hazardous due to mercury content
Mutagenicity and Teratogenicity: Mercury compounds show evidence of reproductive and teratogenic toxicity
Sensitization: May cause allergic skin response in sensitive individuals
