2. HEALTH HAZARD INFORMATION
2.1 Health Effects - Acute Swallowed
POISON! The symptoms of lead poisoning include abdominal pain and spasms, nausea, vomiting, headache. Acute poisoning can lead to muscle weakness, "lead line" on the gums, metallic taste, definite loss of appetite, insomnia, dizziness, high lead levels in blood and urine with shock, coma and death in extreme cases. Eye
Absorption can occur through eye tissues but the more common hazards are local irritation or abrasion. Skin
Lead or lead compounds may be absorbed through the skin on prolonged exposure; the symptoms of lead poisoning described for ingestion exposure may occur. Contact over short periods may cause local irritation, redness and pain. Inhaled
Lead can be absorbed through the respiratory systems. Local irritation of bronchia and lungs can occur and, in cases of acute exosure, symptoms such as metallic taste, chest and abdominal pain, and increased lead blood levels may follow. 2.2 Health Effects - Chronic
Chronic overexposure to this product may affect the following target organs or body systems : blood, digestive, kidneys, nervous and reproductive. Chronic exposure to this product may produce following signs and symptoms : nausea, vomiting, abdominal crapms, diarrhea, constipation, confusion, convulsion, anemia, weakness, fatigue, muscle and joint pain, muscle weakness. Lead is listed as a carcinogen by IARC, NTP. Lead is listed as a teratogen and reproductive toxin. Risk of cumulative effects. May cause birth defects.
2.3 First Aid
Swallowed
Induce vomitng immediately as directed by medical personnel. Never give anything by mouth to an unconscious person. Get medical attention.
Eye
Treat as a foreign body. Flush thoroughly with water for 15 minutes lifting lower and upper eyelids. Seek immediate medical attention.
Skin
Quickly remove contaminated clothing. Wipe of excess from skin. Wash skin with soapy water for at least 15 minutes. Wash clothes promptly. Seek immediate medical attention. Thoroughly clean shoes before re-use.
Inhaled
Move victim away to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Seek immediate medical attention.
First Aid Facilities
Ensure an eye bath and safety shower are available and ready for use.
2.5 Advice to Doctor
Treat symptomatically based on judgement of doctor and individual reactions of patient. Workers with the following conditions warrant particular attention : anemia, pregnant women, breast feeding women and women of child-bearing age.
2.6 Toxicity Data
Oral LD50 = 200 - 2000 mg/kg (Rat) Dermal LD50 = 400 - 2000 mg/kg (Rat) Inhalation LC50 = 2 - 20 mg/L/4hr Investigated as a tumorigen, mutagen, reproductive effector.
3. PRECAUTIONS FOR USE
3.1 Exposure Standards
Threshold Limit Value (TLV-TWA) = 0.15 mg/m Permissible Exposure Limit (PEL) = 0.05 mg/m TLV & PEL are for lead, inorganic dusts and fumes, as Pb.
3.2 Engineering Controls
A system of local/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.
3.3 Personal Protection
Respiratory protection - none required where adequate ventilation conditions exist, If airborne concentration exceeds TLV, a high efficiency particulate respirator is recommended. If concentration exceeds capacity of respirator, a self-contained breathing apparatus is advised. Eye protection - wear safety goggles. Skin protection - wear uniform, apron, butyl rubber gloves.
3.4 Flammability
Strong oxidiser. In contact with easily oxidisable substances may cause ignition, violent combustion or explosion. Increases the flammability of combustible materials. SAFE HANDLING INFORMATION
4.1 Storage / Transport
Keep in a tightly closed container. Store in a cool, dry, ventilated area away from sources of heat or ignition. Protect against physical damage. Store separately from reactive or combustible materials, and out of direct sunlight. Isolate from incompatible substances. Areas in which exposure to lead metal or lead compounds may occur should be identified by signs or appropriate means, and access to the area should be limited to authorised persons. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
4.2 Packaging / Labelling UN No. 1469 Class 5.1 Sub Risk 61 Hazchem Code 2Y Pack Group II EPG No. 31 Shipping Name LEAD NITRATE Hazard OXIDIZING HARMFUL
Risk Phrases R8 Contact with combustible material may cause fire. R20/22 Harmful by inhalation and if swallowed. R33 Danger of cumulative effects.
Safety Phrases S13 Keep away from food, drink and animal foodstuffs. S20/21 When using do not eat, drink or smoke.
4.3 Spills and Disposal
Spills
Avoid generating dust. Remove all unnecessary people from spill area. Wear self-contained breathing apparatus and full protective clothing. Keep combustibles (wood, paper, oil, etc) away from spilled materials.
Collect material in appropriate closed containers and hold for waste disposal DO NOT wash untreated material to sewers, drains or other water courses.
Disposal
Dispose of in accordance with all Local, State and Federal regulations at an approved waste disposal facility or a primary or secondary lead producer for recycle.
4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Strong oxidiser. Lead nitrate must be handled with all the usual precautions for oxidising agents. Lead nitrate is a fire and explosion hazard and must be contained. Fire will generate toxic fumes containing lead and nitrogen oxide gases. Decomposition starts at 250 deg C emitting NO2 and O@, then from above 400 deg C decomposition intensifies and generates basic nitrates and oxides. Lead nitrate may react violently with acids.
Extinguishing Media
Fire-fighters should wear full protective clothing, including self-contained breathing apparatus. Use dry chemical type extinguishers. Use equipment/media appropriate to surrounding fire conditions. 5 OTHER INFORMATION
Other Information
This substance is toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. In the food chain important to humans, bioaccumulation takes place, specifically in marine and terrestrial organisms. It is strongly advised not to let the chemical enter into the environment because it persists in the environment.
