First Aid Measures

Inhalation: Move person to fresh air, monitor breathing, seek medical attention for persistent symptoms such as coughing, tightness in chest, dizziness or headache
Skin Contact: Remove contaminated clothing and shoes, immediately wash skin with soap and plenty of water, medical attention recommended for persistent irritation
Eye Contact: Rinse eyes carefully for several minutes with running water, holding eyelids open, remove contact lenses if present and easy to do, obtain medical advice
Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical help due to risk of lead poisoning
Notes for Medical Providers: Symptoms may be delayed, monitor for signs of lead toxicity, chelation therapy may be required in cases of significant ingestion or absorption

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical powder, foam, carbon dioxide, do not use water streams directly on burning product
Specific Hazards: Product does not burn but hazardous decomposition products (toxic fumes of lead oxides, sulfur oxides) may form in a fire
Protective Equipment: Full protective suit with self-contained breathing apparatus is necessary for fire-fighters
Special Instructions: Evacuate area, prevent runoff from entering drains or watercourses, keep upwind of fire, control ventilation

Accidental Release Measures

Personal Precautions: Wear suitable respiratory protection, gloves, eye and face protection, use chem-resistant clothing
Environmental Precautions: Prevent contaminated runoff, do not let product enter drains or watercourses, notify environmental agencies
Methods of Cleaning Up: Absorb spill with inert material (sand, earth), sweep up and place in a suitable, labeled container for disposal, ventilate area, wash spill site thoroughly after material pickup

Handling and Storage

Handling: Use outdoors or in well-ventilated areas only, avoid contact with skin, eyes, and clothing, prevent formation of dusts, do not eat, drink or smoke while handling, use personal protective equipment
Storage: Keep in tightly sealed container in a cool, dry, well-ventilated place away from incompatible substances such as oxidizers, acids, food and animal feedstuffs, label storage containers clearly, store away from children and untrained personnel, maintain access to spill cleanup materials

Exposure Controls and Personal Protection

Occupational Exposure Limits: OSHA PEL for lead compounds (0.05 mg/m³ as Pb), ACGIH TLV (0.05 mg/m³ as Pb)
Engineering Controls: Chemical fume hood or local exhaust ventilation, prevent dust generation, isolated from incompatible materials
Personal Protective Equipment: Approved respirator (for lead dust/fume), chemical-resistant gloves (nitrile, neoprene), safety glasses with side-shields or goggles, lab coat or protective clothing, closed shoes
Hygiene: Wash hands thoroughly after use, remove contaminated clothing immediately, shower after handling, regular blood lead monitoring for long-term users

Toxicological Information

Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Toxicity: Highly toxic if ingested or inhaled; can be absorbed through skin
Symptoms: Abdominal pain, vomiting, headache, weakness, anemia, encephalopathy in severe cases
Chronic Effects: Prolonged exposure can cause lead poisoning, affecting the nervous system, reproductive system, kidney function, and cause developmental defects in children
Carcinogenicity: IARC: Group 2A (Probably carcinogenic to humans); NTP and OSHA also list lead compounds as probable carcinogens
Additional Information: Occupational exposure may require medical surveillance for lead levels in blood, fertility and prenatal toxic effects documented, more sensitive populations include pregnant women, children, and elderly

Ecological Information

Ecotoxicity: Very toxic to aquatic life, leads to long-lasting environmental effects; acute and chronic toxicity documented in fish, aquatic invertebrates, and algae
Persistence/Degradability: Not biodegradable, lead ions persist in soil and sediment, potential for bioaccumulation in aquatic ecosystems
Bioaccumulation Potential: High, lead bioaccumulates in fish, wildlife, and plants, enters food chain readily
Mobility in Soil: Can migrate through soil and reach groundwater in certain forms, particularly in acidic conditions
Other Negative Impacts: Harmful to birds and mammals, disrupts ecosystems, groundwater and drinking water can become contaminated near industrial sources

Disposal Considerations

Waste Treatment Methods: Dispose as hazardous waste according to local, state, and federal regulations
Waste Codes: US EPA Hazardous Waste: D008 (for lead compounds)
Disposal Containers: Use sealed, labeled drums designed for hazardous waste; do not mix with non-hazardous waste
Precautions: Do not discharge into drains, soil, or waterways; engage certified hazardous waste contractors for disposal
Decontamination: Wash tools and protective wear thoroughly after handling before reuse or disposal, avoid spreading lead contamination
