Impurities: May contain trace cadmium metal, chlorides, or less than 1% water
Inhalation: Remove to fresh air immediately, keep airway clear, provide oxygen if breathing is difficult, begin artificial respiration if not breathing and seek emergency medical attention
Skin Contact: Take off contaminated clothing, wash with plenty of water and soap, do not reuse clothing until properly cleaned, seek medical evaluation if irritation develops
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, seek immediate medical advice
Ingestion: Do not induce vomiting, rinse mouth, give water to dilute if person is conscious, get medical help without delay
Most Important Symptoms: Coughing, breathlessness, chest pain, nausea, abdominal pain, signs of kidney or liver stress, possible delayed symptoms
Medical Attention: Immediate response, consider risk of delayed pulmonary edema and kidney effects
Suitable Extinguishing Media: Dry chemical, foam, or carbon dioxide; avoid using water streams directly on product
Specific Hazards: May release toxic cadmium fumes and oxides during combustion
Protective Equipment: Self-contained breathing apparatus, full protective suit, respiratory protection
Firefighting Instructions: Move containers away from fire if safe, contain runoff to prevent contamination, keep unauthorized personnel away
Personal Precautions: Evacuate area, provide adequate ventilation, use appropriate PPE including respirator with approved filter for particulates
Environmental Precautions: Prevent further leakage or spillage if safe to do, avoid discharge into drains or waterways
Containment and Clean Up: Scoop or vacuum up using non-sparking tools, avoid dust generation, collect in labeled, sealed containers for hazardous waste disposal, thoroughly decontaminate affected area, confirm complete removal with wipe tests if possible
Handling: Use with local exhaust or enclosed systems, avoid skin and eye contact, prevent formation of dust, wash thoroughly after use, do not eat, drink, or smoke around product
Storage: Store in a tightly closed container, in a dry, cool, well-ventilated place, away from acids, strong oxidizers and reducing agents, label storage container clearly, restrict access to trained personnel only
Hygiene Measures: Separate from foodstuffs, avoid cross-contamination with personal items, ensure availability of emergency showers and eye-wash stations
Occupational Exposure Limits: OSHA PEL: 0.005 mg/m³ (as Cd), NIOSH REL: 0.002 mg/m³ (as Cd, fume or dust), ACGIH TLV: 0.01 mg/m³ (inhalable fraction, as Cd)
Engineering Controls: Fume hoods, glove boxes, local exhaust with HEPA filtration
Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), respirators (P100 or better for dust, supplied air for higher concentrations), approved safety goggles, full lab coat or suit

Acute Toxicity: Inhalation, oral, and dermal exposures can be fatal
Chronic Toxicity: Persistent inhalation or ingestion leads to kidney, bone, and lung damage
Carcinogenicity: IARC Group 1 (carcinogenic to humans), NTP listed human carcinogen, evidence for increased risks of lung cancer among exposed workers
Routes of Exposure: Inhalation of dust/fumes, ingestion, skin absorption (minor)
Symptoms of Exposure: Cough, chest pain, headache, nausea, vomiting, kidney/liver function loss over time
Sensitization: Not a known sensitizer
Target Organs: Lungs, kidneys, bones
Other Effects: Reproductive toxicity, possible teratogenic effects
Ecotoxicity: Highly toxic to aquatic organisms, persistent bioaccumulation in aquatic food chains
Mobility: Low mobility in soil, tends to bind tightly to particulate matter
Persistence and Degradability: Does not degrade naturally, remains in environment as metal/oxide
Bioaccumulative Potential: Readily accumulates in aquatic organisms, biomagnification up food webs
Other Environmental Effects: Toxic to algae, fish, invertebrates; risk of long-term ecosystem disruption
Waste Treatment Methods: Treat as hazardous waste using approved incineration or secure chemical landfill, handle according to local, state, and federal regulations
