Suitable Extinguishing Media: Dry chemical, CO2, foam, do not use water streams on burning powder
Specific Hazards: Toxic mercury vapors and oxides may release during combustion, salicylic acid decomposition may add irritating fumes
Protective Equipment for Firefighters: Full protective suit, self-contained breathing apparatus
Precautions: Evacuate surrounding area, avoid inhaling fumes, restrict runoff from entering water supplies or sewers
Personal Precautions: Evacuate unnecessary personnel, use chemical-resistant gloves, goggles, and respirators
Environmental Precautions: Prevent from entering soil, waterways, drains, or sewers
Cleanup Methods: Scoop spilled material into specialized hazardous waste containers, use moistened absorbent material to minimize dust, ventilate area thoroughly, decontaminate surfaces with appropriate mercury neutralizers
Disposal: Follow specialized mercury-contaminated waste regulations, ensure no dispersal of dust or vapors during collection
Safe Handling: Avoid generating dust, operate under fume hood where possible, handle only with trained personnel wearing specified PPE, wash hands thoroughly after use
Storage Instructions: Store in tightly closed, clearly labeled containers, keep in a dry, cool, well-ventilated area dedicated to toxic chemicals
Incompatibilities: Avoid contact with oxidizing agents, strong acids, or bases; store away from food and drink
Occupational Exposure Limits: Mercury exposure limit (OSHA PEL): 0.1 mg/m³ (ceiling), ACGIH TLV: 0.025 mg/m³ (TWA)
Engineering Controls: Local exhaust ventilation, physical containment devices such as glove boxes
PPE: Chemical-resistant gloves, lab coat, eye protection (goggles or face shield), approved respiratory protection when dust or vapor is generated
Hygiene Measures: Change contaminated clothing, do not eat, drink, or smoke during handling, shower after handling significant quantities

Chemical Stability: Stable under properly controlled storage, decomposes at high temperatures
Hazardous Reactions: Contact with strong acids can release toxic mercury and salicylic acid vapors
Materials to Avoid: Oxidizing agents, reducing agents, strong bases
Hazardous Decomposition Products: Mercury vapors, other toxic metal compounds, carbon oxides
Conditions to Avoid: High heat, humidity, moisture
Acute Toxicity: Extremely toxic by ingestion, inhalation, or skin absorption
Chronic Effects: Possible kidney damage, central nervous system impairment, tremor, personality changes, memory loss with repeated exposure
Carcinogenicity: Mercury compounds are classified as possible human carcinogens by some agencies
Reproductive Toxicity: Documented risk to fertility and fetal development in people and animal studies
Target Organs: Kidneys, nervous system, possibly liver
Routes of Exposure: Skin, eyes, inhalation, ingestion
Symptoms: Nausea, vomiting, abdominal pain, dizziness, tremors, hypersalivation, behavioral changes
Aquatic Toxicity: Acute and chronic toxicity to fish, aquatic invertebrates, and algae at very low concentrations
Persistence and Degradability: Mercury accumulates in sediments and biota
Bioaccumulative Potential: High, especially in aquatic food chains; biomagnification leads to amplified effects in predators
Mobility in Soil: Limited; mercury forms stable complexes, but runoff contamination can occur
Hazard to Wildlife: Highly toxic to birds, mammals, aquatic organisms, risk of secondary poisoning up the food chain
Waste Treatment Methods: Collect all waste, contaminated absorbents, PPE in sealed and labeled containers for hazardous waste disposal
Disposal Practices: Do not dispose in regular trash, drains, or local landfill; follow EPA, state, and local regulations for mercury waste
Special Precautions: Prevent release into environment at all stages, final treatment must comply with mercury waste incineration or secure chemical landfill procedures
